摘要: 固体废物焚烧炉飞灰中重金属是造成自然环境空气污染的重要因素。通过对城市废物焚烧炉处理的调查研究，寻找到两种行之有效的固体废物焚烧炉飞灰中重金属萃取络合剂。进一步分析研究，给出此类萃取剂的萃取最佳时间为飞灰溶解处理之后20 h；萃取液最佳酸度为pH 3~10；萃取液最佳浓度为1.5%，使固体废物焚烧炉飞灰中重金属的萃取达到最佳效果。

Abstract: The heavy metals from municipal solid waste(MSW)incinerator fly ashes are important factors to lead environmental pollution.Through investigation on the treatment by MSW incinerators,two effective chelating agents for extraction of heavy metals in fly ashes from MSW incinerators were found.The further analytical studies found that the optimum extraction time for the chelating agents was 20 hours after the fly ashes melted；the optimum pH values were 3～10；the optimum concentration of solution was 1.5%.
