| Abstract: | The optimal experiment conditions for the simultaneous determination of Co,Nb,Fe,B in Ni-Mn-Co-Si-Fe-Nb-B alloy steel by whole-spectrum ICP-AES were studied.The experiment factors including the method for dissolving sample,spectra of analyzed element,interfence of coexisting elements,the background correction and instrument parameters were investigated.The sample is prepaved by fuming the HNO3 and HF.The range of determination is Co 0.5%—12%,Fe 0.1%—3%,Nb 0.1%—5%,B 0.05%—1.0%.The standard recoveries are from 96.6% to 103.7%.The relative standard derivation is from 0.37% to 4.56%.The method is simple,accurate and rapid. |
