汞相的化学分析方法,目前仅分析金属汞和硫化汞两相。本文研究了汞精矿矿浆悬浮电解渣中氯化汞、氧化汞,金属汞和硫化汞四相的分离条件及简捷准确的测定方法。此法基于用无水乙醇浸取氯化汞,离心分离,不溶物用10%硫酸溶液浸取氧化汞,离心分离;不溶物用硝酸(2+1)溶液浸取金属汞,离心分离;不溶物转入50毫升锥形瓶中,用逆王水(1+1)溶液,在电热板上微沸10分钟溶浸硫化汞。分离后所得的含汞溶液均用铜试剂容量法
The method of chemical analysis of mercury phases, currently only analyzes the two phases of metallic mercury and mercuric sulfide. In this paper, the separation conditions of mercury chloride, mercuric oxide, metallic mercury and mercuric sulfide four phases in the slurry of mercury concentrate pulp suspension electrolysis were studied and the determination method was simple and accurate. The method is based on leaching mercuric chloride from absolute ethanol, centrifuging, insolubilizing the mercuric oxide by 10% sulfuric acid solution and centrifuging; Insolubles leaching of metallic mercury with nitric acid (2 + 1) solution, centrifugation; Insoluble The material was transferred to a 50 ml Erlenmeyer flask and dissolved with mercuric (1 + 1) solution on a hot plate for 10 min. After separation, the resulting mercury-containing solution uses the copper reagent capacity method
