【摘要】 本文研究了亚硫酸根和硫代硫酸根在酸性缓冲液中的导数脉冲极谱。含0.5M Na₂B₄O₇和0.02N NaOH的溶液作为底液测定了纸浆废液中硫离子,柠檬酸钠-HCl酸性缓冲液（pH2.5）作为底液同时测定了纸浆废液中硫代硫酸根和亚硫酸根。更多还原

【Abstract】 Derivative pulse polarographic determination of sulfide, sulfite and thiosulfate with hanging mercury drop electrode has been studied. In waste pulp solution, sulfide can be determined in a solution of 0.5M Na₂B₄O₇ with 0.02M-NaOH, while sulfite and thiosulfate can be determined simultaneously in a buffer solution of sodium citrate with hydrochloric acid at pH 2.5.更多还原
