| 摘 要： | 本文研究了Ｃｏ－５－Ｃｌ－ＰＡＤＡＢ间接测汞的方法。用汞定量将Ｃｏ（ＤＤＴＣ）＿２／ＣＨＣｌ＿３溶液解析，Ｃｏ￣（２＋）进入水相与钴试剂反应生成水溶性紫红色络合物，以加入钴试剂的水样为参比，在５７ｎｍ处测定水溶液的吸光度。汞含量在０～５×１０￣（－３）ｇ／Ｌ之间遵守比尔定律，最低检出限为６．４×１０￣（－５）ｇ／Ｌ，该方法操作简单快速，选择性好。

| Abstract: | A method of indirect determination of mercury by cobalt-5-Cl-PADABwas reported.Mercury replaced cobalt of Co(DDTC)_2 in chloroform solutionquttntitatively,then cobalt ion was transferred to aqueous solution,and reacted with5-Cl-PADAB to form Durplish red complex compound.The complex was determined at570nm employing spectrophotometer mode1 721.The calibration curve exhibits linear inthe range of 0 to 5×10￣(-3)g/L for mercury.the detection limit of the method is 6.4×10￣(-5)g/L.This method displayed rapidity,simplicity and distinctive selectivity. |
