摘　　要：It is reported in this paper that trace chlorion in synthetic o benzene dimethanol can be determined directly and accurately by the turbidimetric method (as AgCl).The optimum conditions are also studied.Beer’s law is applicable for the determination of trace concentration of chlordeion in the range of 0～5.0μg/mL.The recoveries of the method are found to be in the range 98.30%～101.13% with RSD smaller than 5.0%.The method is simple and rapid.It is reported in this paper that trace chlorion in synthetic o benzene dimethanol can be determined directly and accurately by the turbidimetric method (as AgCl).The optimum conditions are also studied.Beer's law is applicable for the determination of trace concentration of chlordeion in the range of 0～5.0μg/mL.The recoveries of the method are found to be in the range 98.30%～101.13% with RSD smaller than 5.0%.The method is simple and rapid.
