摘要
采用溴酸钾法测定阻燃聚氨酯泡沫配方中聚醚组分中锑含量时,外加少量还原剂碳,能使样品消化液中少量高价锑完全转化为三价锑,并且提高滴定温度,能减少分析误差,使测定数据精确度提高。
Atimony contents of polyether component in flame retardant foam polyurethane formulations were determined by potassium bromate method. The results show that addition of a few carbon as a reductant can convert Sb' in samples into Sb completely, and increase measurement accuracy, and increase titration temperature and decrease analytical error.
