| Abstract: | A method for the determination of Ca,Fe,Cu and Pb in sphalerite sample by Inductively Coupled Plasma-Atomic Emission Spectrometry（ICP-AES） was developed.Under the optinum condition,the detection limits of Ca,Fe,Cu and Pb were 6.1,8.6,2.2 and 1.5 ng/mL respectively.The recoveries of the method were 95.4%~108.0%,RSD1.6%~3.4%.This method was accurate,quick-acquired and convenient.It was used in the determination of sphalerite and the result was satisfactory. |
