摘要
建立使用电感耦合等离子体原子发射光谱法测定黄金工业废水中的硫酸根含量的方法。针对硫以不同形式存在的样品,采用不同的前处理方法,后使用仪器进行测定,检出限为6.67～11.12μg/m L,加标回收率达99%～101%,重复性实验的相对标准偏差低于3%,结果与国标法一致。
The paper sets up and uses the atom emission spectrometry of the inductance coupling plasma to determine the method of the contents of sulfate radical in the gold industrial wastewater. Aimed at the sample of the sulfur existed in the different forms, the paper adopts the different front treatment methods and behind use of instrument to carry through the measuration and check out the limit as 6.67~11.12μg/mL and the addition standard recovery rate reaches at 99%~101%, the relative standard deviations of the repetition experiment is less 3%. The result and the national standard law are consistent.
