2 Method summary

The sample is dissolved in nitric acid, at a pH of 4.8 to 5.1 in acetic acid - sodium acetate medium, zinc and dithizone can generate red complex Wash was extracted benzene, excess dithizone a dilute sodium sulfide solution was removed, the organic phase was measured at a wavelength of 540nm at its absorption spectrophotometer Luminosity.

3 Reagents

3.1 nitric acid (ρ = 1.42g/mL), of high purity. 3.2 hydrochloric acid (ρ = 1.19g/mL), of high purity. 3.3 sulfate (ρ = 1.84g/mL), of high purity. Aqueous ammonia 3.4 (ρ = 0.90g/mL), of high purity. 3.5 Hydrogen peroxide (30%), pure class distinctions. 3.6 isopropyl ether. 3.7 benzene. 3.8 thiourea saturated solution. 3.9 sulfuric acid - nitric acid mixture (11). 3.10 nitric acid (11). 3.11 hydrochloric acid (11). 3.12 ammonia (11). 3.13 potassium iodide solution (200g/L). stored in a plastic bottle. 3.14 sodium thiosulfate solution (200g/L). Weigh 20g sodium thiosulfate, dissolved in water and diluted to 100mL, transferred to a separatory funnel In with 0.05g/L Diphenylthiocarbazone solution was extracted, the organic phase was extracted until after the green. The aqueous phase was washed with chloroform oscillation The organic phase was obviously not to the green, and then 10mL of carbon tetrachloride oscillation washed once with filtered water in plastic bottles. 3.15 acetic acid - sodium acetate buffer (pH value of 4.8 to 5.1). Weigh 20g of sodium acetate were dissolved in 100mL of water, ice was added 7mL B Dilute acid, add water to 200mL, press thiosulfate (3.14) purification method of purification. 3.16 sodium sulfide solution (0.4g/L). Weigh 1g sodium sulfide, dissolved in water and diluted to 100mL. Pipette solution 4mL, added 96mL of water and shake. The time is now equipped with. 3.17 bromophenol blue ethanol solution (1g/L). 3.18 pairs Diphenylthiocarbazone benzene solution (0.05g/L).
