[Simultaneous determination of 16 elements in decoction solution of Chinese herbal medicine by ICP-AES].
A new method has been developed for simultaneous derermination of 16 elements in decoction solution of Chinese herbal medicine by ICP-AES after pretreatrment the solution with HNO3-H2O2. This method has low and stable blank value. The detection limits of 0.1-5ng/ml for most elements and recoveries of 85-103% were obtained. This method has been applied to the determination of 16 elements in decoction solution of chinese herbal medicine with satisfactory reswls.
