| Abstract: | Samples were digested by wet method,and eliminated interference with lanthanum nitrate,the amounts of Mg,Ca in purslane leaves were determined by FAAS.The purslane leaves are rich in Mg,Ca,1707.9μg/g,2992.8μg/g average levels,respectively.Recovery of method is 88.2%—105.2%,the relative standard deviation is in the range of 0.56—0.93.The method is accurate and reliable. |
