摘　　要：通过胶体滴定法对固体和液体PAC产品进行实验，研究了PAC浓度、pH、盐基度等因素对电荷密度测定的影响规律；当实验pH为5.5左右，混凝剂质量浓度为10~25 mg/L，采用返滴定法可测定PAC的电荷密度。通过对湖水和染料水溶液的混凝脱色实验，表明电荷密度高的PAC产品浊度去除率、脱色率高。Solid and liquid PAC products are te sted by colloid titration. The rules of influences of PAC concentra-tion,pH,basicity and other factors on the determination of electric charge density are studied. When the pH tested is about 5.5,and coagulant mass concentration 10-25 mg/L,the back titration method could be adopted to determine the charge density of PAC. The coagulation and decolorization experiments of the lake water and the dye aqueous so-lution illustrate that the higher charge density of the PAC products is ,the higher the turbidity removing rate and the decolorization rate are.
