内江市生活垃圾填埋场垃圾渗滤液中Pb和Cd的测定

Mensuration and Research of Heavy Metal Pb and Cd in the Landfill Leachate in Neijiang City

采用石墨炉原子吸收分光光度法对内江市高桥镇垃圾填埋场垃圾渗滤液中的重金属进行分析,测定了距垃圾填埋场不同距离地方的渗滤液中Pb和Cd的含量.结果表明:第一测定现场Pb和Cd的含量为第二、三测定现场的4倍左右,通过对垃圾填埋场附近不同地方的重金属Pb和Cd的含量测定并分析垃圾渗滤液中Pb和Cd的来源,确定土壤对重金属Pb和Cd的吸附作用.

Adopt the graphite furnace atomic absorption spectrophotometer to analyze the heavy metal inlandfill leachatein sanitary land fill of Neijiangcity, Menstruate concentration of Pb and Cd in leachate which collect from different places of the sanitary landfill in the city of Neijiang. The content of Pb and Cd in the first measurement locale is about four times of the second and the third measurement locales. By measure different places around the landfill and analyze Pb and Cd sources in leachate, the adsorption of soil to heavy metal Pb and Cd was proved. It can offer basis for wipingoff the heavy mental and studying accumulation of henvy metal in soil.
