在醋酸盐缓冲液存在下,用二乙基二硫代氨基甲酸银(Ag-DDTC)-氯仿交换反应生成汞螯合物,用Hitachi型635A高压液相色谱仪(HPLC)选用μ-Bondapak C_(18)柱(3.9×300mm)分离无机汞和有机汞螯合物的提取
In the presence of acetate buffer, silver chelate was generated by exchange reaction with silver diethyldithiocarbamate (Ag-DDTC) -chloroform. Μ-Bondapak was selected by Hitachi type 635A high pressure liquid chromatography (HPLC) C_ (18) column (3.9 × 300mm) separation of inorganic mercury and organic mercury chelate extraction
