摘要:
采用醋酸缓冲溶液法和HNO3/H2SO4溶液法对磷泥残渣做浸出实验,用火焰原子吸收光度法测定浸出液中铅、镉、铜、锌、铬和镍6种重金属的含量,用可见分光光度法测定其中的砷含量,并讨论了不同方法对重金属浸出的影响.结果表明:残渣中Cu、Cd、Pb、Zn、Ni、As含量较高,而Cr含量较低;在醋酸缓冲溶液浸出体系中,磷泥残渣具有浸出毒性;醋酸缓冲溶液法的提取效果优于HNO3/H2SO4溶液法.
Abstract:
Leaching\|out experiments were carried out on phosphorus sludge residue with acetic acid buffer solution and HNO3/H2SO4 methods. The content of Pb,Cd,Cu,Zn,Cr,Ni and As was determined respectively by flame atomic absorption spectrophotometry and visible spectrophotometry. Then the impact of different methods on the leaching was discussed. The results show that the content of Cu, Cd, Pb, Zn, Ni and As is higher in the residue, and Cr lower, phosphorus sludge residue has leaching toxicity in the leaching system of acetic acid buffer solution, and the extraction of acetic acid buffer solution is better than that of HNO3/H2SO4.
