摘　　要：由于砷及其化合物为剧毒物质 ,固体含砷废料的稳定性及处理方法对环境保护至关重要。本文介绍了固体含砷废料稳定性的测定技术 ,综述了三氧化二砷、砷酸钙、硫化砷。The stability and disposal methods of solid arsenic bearing wastes are important for environment pollution due to the toxicity of arsenic compounds. Determination technology for stability of the solid arsenic wastes was introduced.Common solid arsenic bearing wastes include arsenic trioxide, calcium arsenate, arsenic sulphide, arsenic ferrihydrite and scordite residues. Stability and disposal methods of the arsenic wastes were reviewed.
