Study on the Detection of Multiple Heavy Metal Elements and Selenium Content in Broken Ganoderma lucidum Spore Powder
Microwave digestion was used for pre-treatment,and the content of lead,arsenic,mercury,cadmium,chromium,nickel,and selenium elements in broken Ganoderma lucidum spore powder was determined by triple four stage rod inductively coupled plasma mass spectrometry.The method conditions were optimized and discussed,and 20 batches of broken Ganoderma lucidum spore powder were determined.Experiments have shown that lead,arsenic,mercury,cadmium,chromium,and nickel elements can achieve good measurement results using internal standard calibration quantification in helium collision reaction mode and selenium element in oxygen reaction mode.Under optimized conditions,the linear relationship of each element is good,and the detection limit can all reach μg·kg-1 level.The recovery rates of lead,arsenic,cadmium,chromium,nickel,and selenium with added standards range from 90.3%to 105.0%,while the recovery rates of mercury with added standards range from 82.1%to 92.5%.The precision of the method is within 5%.This method has simple pre-treatment operation,high detection sensitivity,and good stability,providing good technical support for the determination of multiple elements in Ganoderma lucidum spore powder.
