Abstract�� The organic precipitating agent A was used to eliminate iron from liquid sulfuric acid aluminum by precipitation in order to improve the purity of liquid sulfuric acid aluminum.The experiment was done on the factors such as amount of precipitating agent,the operating temperature and time.When the amount of the precipitating agent was 8%,the operation was at 25 �� for 60��70 min,the content of iron contained in the liquid sulfuric acid aluminum was less than 30.0��10~6.
