摘要
磷泥是电炉法生产黄磷过程中产生的主要副产物之一,针对磷泥中黄磷回收的方法和研究现状,介绍了水煮法、蒸馏法、电场法、溶剂萃取法、盐酸-硝酸法、纯碱法、氨解法、碳铵-烧碱-双氧水法等,讨论了各种方法的特点,指出存在的问题和今后的研究重点。
Electric furnace produc tion of phosphorus yellow phosphorus sludge is generated during one of the main by-products.This paper analyzed the recovery methods and research status,introduced water boiling method,distillation method,electrical field method,solvent extraction method,hydrochloric acid-nitric acid method,soda ash method,ammonia analytical method,ammonium carbonate-caustic soda-hydrogen peroxide method and so on,and discussed the characteristics of every method,then pointed out the existed problem and the research emphases in the future.
