Determination of 9 kinds of metal elements in fertilizers by super microwave digestion and ICP-MS
A method for the determination of nine pollutant elements,namely V,Cr,Co,Ni,As,Cd,Hg,Tl and Pb in various types of fertilizers was established by using inductively coupled plasma mass spectrometry(ICP-MS),super microwave digestion and optimization of the digestion conditions for different types of fertilizers.The linear correlation coefficients of this method were all greater than 0.9999,and the limits of detection of the method were in the range of 0.000500-0.0293 mg/kg.The recoveries of the spiked elements were 85.0%-110%,and the method is sensitive and accurate,which can realize the accurate determination of the multiple elements in different types of fertilizer samples.
