Abstract: |
Through a series tests of corrosion behavior, acute toxicity and leaching toxicity for chemical industry solid waste in a chemical plant in Chongqing, China, a corresponding method of sample collection, preparation and toxicity analysis were established in the laboratory. The cyanide compound and pH value of the solid waste were determined by using this method. The results show that those cyanide waste can be defined as hazardous and corrosive waste according to China standard GB5085.1~GB5085.3-2007. By the discussion on the changes of these indicators, the researches of this paper provide a basis for cyanide slag disposal and utilization, and can be used as the guideline.
