摘　　要：氢氧化锂在特殊环境中用作空气净化剂,吸收人体呼吸排出的二氧化碳。本文对孤立作业体系使用的氢氧化锂的再生进行了研究,测定了氢氧化锂吸附后的主要成分,采用苛化法制备一水氢氧化锂,产品纯度符合GB/T 8766-2002工业级标准。Lithium hydroxide is used as purificant in special environment to adsorb CO2 breathed out by person. The regeneration of lithium hydroxide used in isolated system has been studied. The primary components of spent lithium hydroxide are determined. Causticization is adopted to prepare LiOH · H2O and the purity of the product can meet the GB/T 8766 -2002 industrial grade standard.
