Abstract: A method for determination of eight heavy metal elements including chromium,nickel,cobalt,vanadium,molybdenum,antimony,thallium and lead in various cosmetics was established by using super microwave digestion and inductively coupled plasma-mass spectrometry (ICP-MS).The samples were digested with nitric acid-water system under assistance of super microwave irradiation,detected by ICP-MS and quantified by external standard method.Under the optimized conditions,good linear relationships of eight heavy metals are showed within the mass concentration range of 0-100 μg/L with the correlation coefficient larger than 0.999.The detection limits of the method are not higher than 0.012 mg/kg.This method has been successfully applied to the detection and analysis of eight heavy metal elements in various kinds of cosmetics.The recoveries of the spiked samples are between 88.5%-108.5% with the relative standard deviation not more than 3.89%.This method is simple,accurate and precision,which provides an effective method for the rapid determination of eigth heavy metals in various cosmetics.
