摘要
为了测定成膜剂中铝的含量,采用浓碱沉淀分离法,将成膜剂中大量的Ce4+、Zr4+干扰元素与Al3+分离,再用EDTA反滴定测定,测定结果准确、可靠。
In order to determine the content of main components of filmogen treating metal surface,using concentrated base to separate a large number of interfering elements such as Ce^4＋,Zr^4＋from Al^3＋,and through EDTA back titration to determine content of aluminum,the result is tested to be accurate and reliable.
