摘要
通过对测定硫化物标准曲线的质量保证及不同污染程度水样的前处理方法的探讨 ,得出硫化物标准溶液需现用现配及针对污染程度不同的水样分别采取直接测定、抽滤测定和酸化
By studying on determining the quality factors of the sulfide standard curve and on the pre-treament methods for different water samples, the conclusions are obtained that the standard liquid of sulfide has to be prepared for using immediately, and the direct determination method, the extract filter determination method and the acidization-air injection determination method should be used separately for samples with different pollution degree.
