主　　题：analytical method for sphalerite CIELAB colorimetry no secondary pollution original state detection 

摘      要：Currently,most of the methods formineral materials analysis generate secondary pollution,which is detrimental to human *** instance,traditionalmethods for sphalerite analysis in the zinc(Zn)smelting industry including chemical titration,atomic absorption spectrometry,and inductively coupled atomic emission *** indicators and toxic heavy metals are used in the analytical processes,causing severe *** some methods,liquid is transformed into gaseous plasma,which is more dangerous to human *** to large quantities of sphalerite being used,secondary pollution cannot be *** study proposes a green analysis method for the detection of sphalerite based on colorimetry,which does not generate secondary *** results show that the strong substitution ability of iron(Fe)for Zn contributes to their inverse correlation in *** lattice parameters decrease with the increasing Fe content,resulting in a darker ***,key colorimetry parameters of L*,a*,and b*show clear linear correlations with the Zn and Fe *** with traditional approaches,this new method is environmental friendly with high sensitivity and *** relative error and relative standard deviation were less than 10%and 5%,*** study provides a significant reference for nonpollution determination of other mineral materials.
