This is' Description[7]='the phosphorus stock solution.' Description[8]='' Description[9]='Preparation of the Calibration Line' Description[10]='' Description[11]='From the stock solution standard solutions were made to 100.0 ± 0.3 ml' Description[12]='volumetric flasks. To these flasks 0.500, 1.000, 2.000, 3.000 and 4.000 ml of' Description[13]='the stock solution was pipetted and the flasks were filled to the mark. The' Description[14]='pipetting operations were carried out using graduated pipettes. From the data' Description[15]='in the manufacturer''s catalogue it appears that for ± 0.5% of the pipetted' Description[16]='volume can be used as the estimate of the calibration uncertainty. For' Description[17]='obtaining the calibration line one measurement was made with each of these' Description[18]='solutions. For the measurement 10.00 ml of the solution was pipetted' Description[19]='(calibration uncertainty of the pipette ± 0.03 ml) into a small stoppered' Description[20]='reaction flask. The same pipette was used for pipetting all the standard' Description[21]='solutions and the sample solution. To eliminate the carryover effect the' Description[22]='pipette was rinsed two times with the respective solution before pipetting.' Description[23]='10.00 ml of molybdatovanadate reagent was added (calibration uncertainty of the' Description[24]='pipette ± 0.03 ml). The same pipette was used for adding the reagent both for' Description[25]='the calibration solutions and the sample solution. The solution was mixed and' Description[26]='let stand for 10 minutes. The solution was then transferred to' Description[27]='spectrophotometric cell (the cell was twice rinsed with the solution before the' Description[28]='measurement) and the absorbance was measured against blank. The absorbance' Description[29]='values obtained were: 0.086, 0.173, 0.341, 0.518 and 0.686 AU, respectively for' Description[30]='the five solutions.' Description[31]='' Description[32]='Preparation of the Sample' Description[33]='' Description[34]='The amount of sample (that had been thoroughly mixed and sieved) taken for the' Description[35]='analysis was 2542.1 g. The sample was carefully mixed with 1 g of calcium' Description[36]='carbonate and ashed in a muffle furnace at 550 °C. The ash was transferred to a' Description[37]='250 ml beaker with 50 ml of water. 6M HCl solution was added in small batches' Description[38]='until the bubbling stopped. Then additional 10 ml of 6M HCl was added and the' Description[39]='contents of the beaker were evaporated to dryness. 10 ml of 1M HNO3 was added' Description[40]='to the residue and boiled on sand-bath. The resulting liquid was quantitatively' Description[41]='transferred to 500.0 ± 0.4 ml volumetric flask and filled to the mark with' Description[42]='water.' Description[43]='' Description[44]='Measurement of the Sample Solution' Description[45]='' Description[46]='The same method was used for measurement as in the case of the calibration' Description[47]='standard solutions with the only difference was that before measurement a small' Description[48]='part of the solution was filtrated and 10 ml taken from the filtrate. The' Description[49]='reading obtained was 0.474 AU. The same photometer was used for all' Description[50]='measurements. It has digital display with 3 digits after the comma. From the' Description[51]='documentation of the photometer the following data were found: "photometric' Description[52]='reproducibility ± 0.002 AU; stability ± 0.0003 AU/h; baseline stability ± 0.001' Description[53]='AU/h". These data correspond to a new instrument, but the used photometer was 8' Description[54]='years old. In addition, with the current method there is the additional source' Description[55]='of uncertainty, which is far bigger than the purely instrumental repeatability' Description[56]='- the chemical reaction. Therefore the data on drift and reproducibility were' Description[57]='determined experimentally in the laboratory (see below).' Description[58]='' Description[59]='Parameters Determined Earlier at the Same Laboratory or Obtained from Other' Description[60]='Sources' Description[61]='' Description[62]='1. Repeatability of weighing. By repeated weighing (10 times) of a sample that' Description[63]='had similar mass to the sample of this work it was found that the repeatability' Description[64]='standard uncertainty of weighing was u(m, rep) = 0.00017 g (found as standard' Description[65]='deviation of the masses). The weighing was done as tared weighing, so the' Description[66]='uncertainty originating from taring operation is included in the uncertainty' Description[67]='estimate. The repeatability is essentially independent of the mass.' Description[68]='' Description[69]='2. Drift of weighing. Drift is more difficult to determine than repeatability.' Description[70]='The drift is not necessarily the same on different days and if the laboratory' Description[71]='is not air-conditioned (as is the case in this example) then it depends on the' Description[72]='season. Based on long-time observations it was found that during 4-5 hours the' Description[73]='balance drift is no more than ± 0.0002 g.' Description[74]='' Description[75]='3. Repeatability of pipetting. For those cases when the repeatability is not' Description[76]='determined directly at the laboratory, it is safe to assume that the' Description[77]='repeatability standard uncertainty of pipetting is 0.4% of the pipetted volume.' Description[78]='' Description[79]='4. Repeatability of filling volumetric flasks. With all volumetric flasks it is' Description[80]='assumed that the flask is filled dropwise and the uncertainty is ± 1drop, that' Description[81]='is ± 0.03 ml.' Description[82]='' Description[83]='5. Sample preparation recovery R. Extraction recovery was determined using a' Description[84]='CRM with similar composition and phosphorus content. (6.8 g/kg). It was found' Description[85]='that R = 0.95, u(R) = 0.04. The recovery determined this way takes also to some' Description[86]='extent into account the uncertainty due to the inhomogeneity of the sample (be' Description[87]='careful, however, because CRM-s tend to be more homogenous than the usual' Description[88]='samples).' Description[89]='' Description[90]='6. Repeatability of the standard solution measurement. The repeatability was' Description[91]='determined at two different concentration levels: one near 0.0 AU and the other' Description[92]='near 1.0 AU. Every time new amount of the sample solution was used and the' Description[93]='photometric reaction was carried out. This way the determined repeatability' Description[94]='includes not only the effects coming from the photometer but also the possible' Description[95]='variations of the chemical reaction (that are far bigger, in fact). It was' Description[96]='found that the standard uncertainty of repeatability was 0.0012 AU and 0.0021' Description[97]='AU at absorbances 0.0 and 1.0 AU, respectively.' Description[98]='' Description[99]='7. Repeatability of the sample measurement. The repeatability uncertainty of' Description[100]='the sample measurement is expected to be somewhat higher than the repeatability' Description[101]='of the standard solution measurement, because various extraneous ions are' Description[102]='present in the solution. It was found that at 0.5 AU level the repeatability' Description[103]='uncertainty was 0.0030 AU.' Description[104]='' Description[105]='8. Drift of the photometer reading. Drift is more difficult to determine than' Description[106]='repeatability. The drift is not necessarily the same on different days and if' Description[107]='the laboratory is not air-conditioned (as is the case in this example) then it' Description[108]='depends on the season. Based on long-time observations it was concluded that' Description[109]='the drift of the photometer during 4-5 hours is not ore than 0.002 and 0.003 AU' Description[110]='at absorbance values 0.0 and 1.0 AU, respectively.' Description[111]='' Description[112]='9. Linearity of the calibration graph. It was found that in the concentration' Description[113]='range 5 .. 40 mg/ml the calibration graph is linear.' Description[114]='' Description[115]='10. Temperature in the laboratory. It was found that the temperature in the' Description[116]='laboratory during the measurement differed from 20 °C not more than ± 3 °C,' Description[117]='also all solutions and volumetric ware were at that temperature during the' Description[118]='work.
