| Abstract: | A method for the simultaneous determination of six heavy metal elements, Cu, Zn, Ni, Cr, Pb and Co, in stream sediment was established using ICP-OES together with automated sample digestion system. The correlation coefficients of calibration curves were over 0.999 and the limits of detection were from 0.000 2 to 0.02 mg/L for the six elements. The national standard soil reference material (GBW07361) was analyzed by the described method and the results indicated that the precision and accuracy of the method met the environment monitoring requirements. The results indicated that the method is easy and reliable for determining heavy metal elements in stream sediment. |
