Open publisher page 0 citations

Abstract

The content of Manganese in Milk tea powder samples was digested by Microwave technique,and determined by flame atomic absorption spectrometry.Under selected Experimental conditions,the characteristic mass concentration for Mn is 0.059μg/mL/1% with the recoveries of 89.1%—110.4%,and RSD(%)was less than 1.36%.The method is simple and the results are satisfactory.
