摘　　要：用滴定法测定碱锰扣式电池锌膏中的汞含量。该方法用CuCl2作为显色剂,用二乙氨基二硫代甲酸钠标准溶液进行滴定,滴定后用CCl4萃取,使溶液中显色的Cu(C4H10NaS2)2指示滴定终点。在pH>8时,汞的回收率接近100%,滴定的相对标准偏差≤3.6%,干扰离子少。The titration method was used to determine the mercury content in zinc gel of alkaline Zn/MnO2 button cell. In this titration method, CuCl2 was used as color developing reagent and （C2H5）2NCS2Na standard solution was used as titrant. Cu（C4H10NaS2）2 was extracted by CCl4 during the process of titration to indicate end-points of titrations. When pH 〉 8, the recovery of Hg was about 100%, relative normal titration error≤ 3.6 % and interfering ions were very few.
