Open publisher page 0 citations

Abstract

Chrome azurol S coloured system is used to determine Al(III) in the silicon-aluminum residue.The measuring condition of this method is studied.In pH4.7 Hac-NaAc duffer solution,the maximum absorptio is at 558nm.Beer's law is obeyed up to 15μg of aluminum in 1mL and linear correlation is better. The result indicated that the method has been satisfactorily applied to the determination of low content of Aluminum.
