摘　　要：在酸性条件下,硫化物通过酸化吸收装置转化为H2S,在乙酸锌-乙酸钠吸收液中,与二甲基对苯二胺,硫酸铁胺溶液反应生成蓝色的络合物,用分光光度比色定量分析。Under acidic conditions, the sulfide is converted to H2S by an acidification absorption device. In a zinc acetate-sodium acetate absorption solution, reacting with dimethyl p-phenylenediamine and ferric sulfate solution to form a blue complex. Quantitative analysis by spectrophotometric colorimetry.
