| Abstract: | Two practical methods for the determination of aluminium content in pastry were introduced. Aluminium content in pastry was determined with dry digestion by UV,taking the determination of aluminium content by ICP- OES.These two methods avoided the perchloric acid＇s effect on the color reaction,the recovery of rate and precision were meetting the requirements. Dry ashing digestion method by UV was convenient and low detection cost,ICP- OES stability was good,but the cost of detection was high. |
