摘　　要：研究了氧瓶燃烧-分光光度法测定聚氨酯泡沫塑料中氯含量的方法.采用氧瓶燃烧法分解聚氨酯泡沫塑料,然后用硫氰酸汞分光光度法测定其中氯含量.实验结果表明,氧瓶燃烧-分光光度法能有效地测定聚氨酯泡沫塑料中氯元素的含量,该方法简便、准确、实用性强、灵敏度高,适合快速分析.This article studied on the oxygen flask combustion spectrophotometry for determining the chloride content in polyurethane foam. Polyurethane foam was decomposed firt by oxygen flask combustion method, then the chloride content was determined with mercury thiocyanate spectrophotometry. The experimental results indicated that the oxygen flask combustion methodspectrophptometry can determine the chloride content in polyurethane foam effectively. This method was simple, accurate and highly practical, it sensitivity is high, and suitable for the rapid analysis.
