摘要：Theconversion of solid waste into condary resources has becomea prerequisite for the sustainable development of the industry. Thisstudy focud on the development of the detoxification process forspent carbon cathode (SCC) without environmental pollution risks andthe exploration of t小女孩可爱头像
he recycling direction of recovered carbonaceousmaterials. First, the mechanism of thermodynamic conversion and decompositionof toxic substances was explored. Parameters of NaOH–Na 2 CO 3 binary molten salt roasting were optimizedthrough an orthogonal design and a single-factor experiment, and gasrelea behavior during detoxification treatment was investigated.Results showed that most of the fluoride and cyanide were dissociatedand decompod, and the leaching concentration of fluoride and cyanidewas as low as 7.58 and 0.12 mg/L
