摘要
建立了一种采用氮吹-碘量滴定测定化妆品中碱金属硫化物和碱土金属硫化物含量的方法。经过对试刺和吸收条件的优化,结果表明,方法检出限可达0.2%,加标回收率达到80%以上,可简便、快捷地检测化妆品中碱金属及碱土金属硫化物的含量。
The iodometric method for the determination of content of alkali metals and alkaline earth sulfides in cosmetics was established in this paper. By optimizing the conditions of reagents used and absorption, using nitrogen blowing - iodometric ti tration, the contents of alkali metals and alkaline earth sulfides in cosmetics were measured. The results showed that the detection limit of the method was 0.20%, the recovery was higher than 80%. It is a simple and quick method for determining the contents of alkali metals and alkaline earth sulfides in cosmetics.
