The toxicity of spent potliner is discussed in this paper according to the research on main constitutes,microstructure,tiny section components,ash content and hydrating reactivity of SPL. The result indicates that the toxicity of SPL mostly rests with its leaching toxicity,contaminates in SPL are mainly dissolving fluorides and cyanides,these contaminates mostly come from electrolyze which infiltrate into the potliner and cause erosion,contents of dissolving F— and CN— in SPL are far more than the permitted discharge in national standard. SPL, which seriously does harm to eco-environment is classified as hazardous solid waste and should be detoxified as soon as possible.

本文从废槽内衬的物相组成、微观形貌、微区成分、灰分、水化反应性五方面研究了废槽内衬的危害性，结果表明，废槽内衬的危害性主要在于其浸出毒性，毒害物质主要是可溶氟化物和氰化物，毒害物质主要来自于电解质对内衬的渗透、侵蚀，废槽内衬中可溶F—和CN—的浓度远远高于国家标准规定的允许排放量，因此废槽内衬被认定为固体危险废弃物，严重危害生态环境，必须进行无害化处理。
