Except for the established ones, the standard titration solutions, standard starting liquid preparations and finished products in this inspection are all made from hot-drying materials of GT/T601 Ti02GT/T3, and the laboratory water used is in accordance with the third grade specification of 3/TGH2. The test pressing is refined to C.9 and weighed. 5.1 Weigh 0.4% or 0.6% potassium chloride in 1cc ml of water, add 5% ethyl acetate and 5g/mL sodium chloride, and titrate in a cup [c(AgVC) = u, ml/L protected from light until a milky white color appears. The total amount of potassium chloride is calculated as follows: Where: x is the mass fraction of potassium chloride, mX10Q0 is the volume of the effective titration with silver iodide standard, m1/mL is the volume of the effective titration with silver iodide standard, m1/mL is the volume of the effective titration with silver iodide standard, m2/mL is the concentration of the diluted solution, m3/mL is the mass fraction of the solution, and the titration rate is 11rm1 The content of carbon dioxide in the sample is not less than 1.5-1.5 when measured by a chromatometer. 5.3 Determination of turbidity test Weigh 20 test pieces and collect 100 L of water. The turbidity shall not exceed 440 °C. Photograph the secondary sample. 5.4 Determination of turbidity of water: In the water sample, keep it warm for 1 h and pass it through a constant weight pot. Wash the solution by heat to remove the ions. The filtration mass calibrator is as follows: 5.5 Mixed salt HG/T3570-2001 Weigh 2 test pieces and dissolve them in 21 μl.

Add 1% acetic acid to adjust the pH value to 5, then add 4 mL of isobutylbenzene (MEBK), plug the lid, add 1 mL of MEBK for 2 min, and let stand for 2 min. After separation, collect the organic phase: add 1 mL of MEBK to the aqueous phase for the second extraction. Combine the two extractions and determine according to G/T1072419496.2. 5.10.2.2 Determination of the selected extractions: Weigh 125 mL of sample, add water to a volume of 0.5 mL, and freshly dilute the extract. Add 10 mL of water to each of the four 125 mL separation funnels, accurately add 20 μL of the sample solution, one portion as the final sample, and the other three portions as standard 1.( , chain 0.5J + and then make the complexation according to the steps of making the standard curve. The organic rate is determined according to the provisions of 6.2.1 in G/T10721--1589. The lead content of the test sample is one or two times higher than that of the oxygen, so the amount of standard liquid added is also large. The staggered time should be reduced as much as possible. MIBK should be diluted 1I times.
