Determination of multiple metal elements in garbage leachate by ICP-OES
In this experiment,an electric heating plate-nitric acid-perchloric acid was used for pre-treatment of landfill leachate,and an ICP-OES analysis method was established for simultaneous determination of copper,zinc,lead,cadmium,chromium,nickel,iron,manganese,tin,and antimony elements in landfill leachate.The results showed that the linear correlation coefficients of 10 elements determined by this method ranged from 0.9993 to 1.0000,and the detection limit of the method was 0.0004～0.0070mg·L-1.The method has good precision and high accuracy.The established method was used to determine the leachate of a landfill site in Guangxi.The SD of 10 elements was 0.01％～6.87％,and the recovery rate was greater than 100％.The method is accurate,reliable,convenient and fast,and suitable for the determination of copper,zinc,lead,cadmium,chromium,nickel,iron,manganese,tin,and antimony elements in different concentrations of landfill leachate.
