电感耦合等离子体质谱法测定松潘地产大黄药材中重金属元素
Content Determination of Heavy Metal Elements in Rhubarb from Songpan County of Sichuan Province Using Inductively Coupled Plasma-Mass Spectra
摘要
Abstract
Objective To determine the contents of plumbum (Pb) , cadmium (Cd) , hydrargyri ( Hg) , cuprum (Cu) and arsenic (As) in thubarb from Songpan county of Sichuan province,in an attempt to evaluate the safety of thubarb based on whether or not the contents of heavy metal elements are out of limits.Methods Rhubarb samples were processed by microwave digestion (MVD). The contents of five heavy mental elements in thubarb from different areas and cultivations were detected by inductively coupled plasma-mass spectra (ICP-MS). Results The detection limits of five heavy metal elements ranged from 0. 02 to 0. 30 ng/ml. This method had good linear correlation for each element (r>0. 999 1). The contents of five heavy metal elements from 20 samples of thubarb were within the limits of national standards. Conclusion Based on the contents of heavy metal elements being within the limits,it can be concluded that thubarbs from Songpan county are safe for medicine,and Songpan area is suitable for the cultivation of thubarbs.关键词
