摘　　要：针对废塑料聚氯乙烯样品,以氧瓶燃烧分解试样,碱液吸收,佛尔哈德法滴定。详细考查了有关的样品分解、气体吸收、试液滴定条件。方法应用于多种废弃塑料中氯的测定,与同类方法相比简便、快速。对大量含氯5％～50％的塑料样品分析结果令人满意。The determination of chlorine in waste plastics has been developed. The method was base on an oxygen -flask combustion then alkali solution absorption and titrated analysis of Volhard. The optimum conditions of sample decompose , absorption of chlorine and titrated operation has been investigated. The method is rapid, accurate and convenient applied to determination of chlorine 5 - 50% in the waste plastics, with satisfactory results.
