【Abstract】 The quantitative analysis of S in sulfide ore,pre-treated by mixed acids ,was performed using inductively coupled plasma-atomic emission spectrometry(ICP-AES). The analytical spectral line was screened and the standing time was optimized. The RSD was lower than 1.50% which matched with the national standard value well.更多还原
