%X The traditional measurement methods of 3 aluminum species and its total aluminum content in polyaluminum solutions are Al-Ferron timed complex spectrophotometry and EDTA chelatometry respectively. But each of these methods has different deficiencies. Microwave digesting technical had been applied to radiate the ferron mixed chromogenic solutions and to mensurate the concentration of total aluminum Al_T at the same time. Test results show that, (1) it has a very great influence on the measured value whether or not the ferron mixed chromogenic solutions after deploys different time, but it can been put into use immediately after microwave digested 30 s, which overcomes the weakness that must set 5 days at the traditional method. (2) It is proved at the same time, that it can assay quantitatively the total aluminum content in some water treatment reagents of aluminum salt solutions conveniently, by microwave digesting 2 min for the mixed solutions of the ferron mixed chromogenic solutions and the polyaluminum solutions. The feasibility of this method has been verified by modified Al-Ferron timed complex spectrophotometry at the same time.
