| Abstract: | A new method of simultaneous determining of Si,Fe,Cu,Ga and Ti in aluminium with one dose of solution is put forward. The samples are decomposed with sodium hydroxide and acidized with hydrochloric acid. And then, use the silicomolybdic blue photometric method for determination of Si content, the orthophenanthrolene photometric method for determination of Fe content,the biscyclohexanon oxalyldihydrazone photometric method for determination of Cu content,the butylrhodamine B photometric method for determination of Ga content,and the diantipyrylmethane photometric method for determination of Ti content. The results obtained by this simple,rapid and accurate method for analysis of Al sample comply with the theoretical value. |
