Due to only the acidity of gastric juice was considered for the determination of soluble elements in toys and pencils by the standard method, the simulant conditions for the determination of soluble elements As, Ba, Cd, Cr, Hg, Pb, Sb, Se were studied, which included not only the aciditiy of gastric juice but also the influence of saliva.
国内外标准中关于玩具、铅笔中可溶性有害元素砷、钡、镉、铬、汞、铅、锑、硒的测定只考虑了胃液酸度的影响这一不足,在充分考虑唾液、胃液两种介质的影响下,建立了新的模拟溶出条件,将改进后的方法用于检测玩具、铅笔中8种有害元素,测定结果更切合实际。
Simultaneous determination of eight hazard elements was studied in toys and pencils with microwave digestion and ICP-AES.
