| Abstract: | The heavy metals including Cr,As,Hg,Cd and Pb in sheep manure board were determined by inductively coupled plasma mass spectrometry(ICP-MS),and the determining conditions of instrument were optimized.The detection limits of method were as follows:Cr 0.39ng/mL,As 0.12ng/mL,Hg 0.24ng/mL,Cd 0.090ng/mL,Pb 0.49ng/mL.The RSDs of the method were in the range of 4.9%—14.3%,and the recoveries ranged from 92.0%—110.0%.The method is applied to the detection of heavy metal elements in the similar organic samples. |
