Determination of releasing values of heavy metals from tailings leached by beneficiation reagents by ICP- AES
2013
A method for the determination of releasing values of heavy metals Cd,Cu,Pb and Zn from tailings leached by sulfur bearing beneficiation reagents by ICP-AES( inductively coupled plasma-atomic emission spectroscopy) has been developed in this study. The selection of instrumental parameters,the analytical wavelengths and interferences were discussed. The results showed that the correlation coefficients,relative standard deviations and recoveries of the method were 0. 9999 ~ 1. 0000,1. 1% ~ 4. 1% and 80. 0% ~ 106. 6%,respectively. This method is sensitive,accurate and simple for analysis of Cd,Cu,Pb and Zn.
