从无机实验废水中提取银、钴、碘的研究

A Study of Extracting Silver,Cobalt and Iodine from Inorganic Experimental Wastewater

随着经济的发展、科研实验的剧增和高校的扩招,实验室产生的三废越来越多。因此,将各种实验废水进行回收处理,变废为宝,这对保护环境、节约资源具有重大意义。设计不同方案从"三氯六氨合钴(Ⅲ)的合成和组成的测定"的实验废水中分别提取银、钴、碘等元素并对所得物质进行了定性定量分析。

With the development of economy, the rapid increase in scientific experiments and the expan- sion of the universities, there are more and more ＂three wastes＂ from the labs. Therefore, if various experimental wastewater are processed and recycled, they may be turned into useful substances, which is of great significance for protecting the environment and saving resources. In this paper, silver, cobalt and iodine are extracted from the ex- perimental wastewater produced by the experiment the synthesis of [ Co（ NH3 ） 6 ] Cl3 and the determination of Cobalt content. Different programs are designed to extract the precious metal silver. From the study, it is found that the best program is using Zinc as reductant. Finally, the substances obtained are analysed qualitatively and quantita- tively.
