摘　　要：垃圾渗滤液中的高浓度重金属离子严重抑止了废水生化处理过程中微生物的生长与代谢。通过建立多元线性回归模型,结合pH络合滴定方法,实现了同时测定垃圾渗滤液中络合稳定常数极为接近的多种重金属离子浓度。该方法操作简便,准确可靠,适用于大批量相同组成试样的分析。The high concentration of heavy metal ion from landfill leachate restrains the growth and metabolize of microorganism badly in bio-chemical treatment of wastewater. This article combines regression equation with the method of pH complexometric titration through the building of multiple linear regression method principle model. The method realizes the determination of multi-component heavy metal concentration which have very similar stability constants simultaneously from landfill leachate. This method is simple and credibility.
