摘要
目前分离提纯碲的方法主要有苏打粉焙烧法、碱性高压浸出法、硫酸化焙烧法、氧化酸浸法、萃取法、液膜法、微生物法、电解精炼法、真空蒸馏法、区熔精炼法等,其中电解精炼法得到的碲的纯度达到99.99%,真空蒸馏碲的纯度达到99.999%,区熔精炼碲的纯度可达99.999995%,本文综述了以上分离提纯碲的方法。
The methods of extracting and refining tellurium presently were mainly soda roasting,autoclaving in general basic solution,sulfating roasting,oxidative leaching in acid solution,solvent extraction,emulsion liquid membrane,microbial method,electrorefining,vacuum distillation and zone melting etc.The tellurium using electrorefining was 99.99% and the vacuum distillation refining was 99.999%,but the tellurium of zone melting refining can reach 99.999995%.In the paper the methods of extracting and refining tellurium were summarized respectively.
