摘要
本文以典型含氰固废样品为研究对象,采用碱溶浸提的前处理方法,通过一系列对比试验,探讨了提取剂p H值、液固比、提取时间和提取次数等因素对固体废物中氰化物碱溶浸出效率的影响,为固废中氰化物的准确测定提供了科学有效的支持。
In this article,by using the typical solid wastes containing cyanides as the research samples and alkali dissolution as pre-treatment method, via a series of contrast experiments, the factors affecting leaching efficiency such as pH of extracting fluid, liquid-to-solid ratio, leaching time and extracting times were discussed,which provides scientific and effective support to the detemnination of cyanides in sohd wastes.
