화학반응 공정에서 발생된 폐자원의 유해특성 및 재활용 적정성 평가 = Assessment of Hazardous Properties and Adequate Recycling of Waste in Chemical Reaction Process

다국어 초록 (Multilingual Abstract)

This study seeks to establish the appropriateness of recycling for waste that includes catalysts and bauxite-treatedresidue. Samples of these wastes were subjected to chemical composition, elution, and contents analyses as well asexperiments to identify hazardous properties. Waste that included catalysts had concentrations of Hg that exceeded theregulated limits stated of the Waste Management Act in Korea. Moreover, analyses revealed that catalyst waste had oilcontents of 3.7% and thus was flammable. Elemental analyses of samples of bauxite-treated residue revealedconcentrations of Cd, Pb, Cu, As, and Hg that met the criteria for area 1 of soil contamination. However, pH of the eluatewas 10.1, which is relatively high, and so was judged to be corrosive. These results necessitated that bauxite-treated residuewith high Na, Mg, and Al contents be assayed for reactivity with water. If metal content exceeds 5% in bauxite-treatedresidues, then our study suggests that the waste be assessed for flammability and spontaneous combustion.
