| Abstract: | The selective sequential extraction method developed by Tessier was used to analyze the chemical speciation of heavy metals(Cu,Zn,Pb,Cd,) in sludge of Qidaowan Wastewater Treatment Plant in Urumqi,and the bioavailability of heavy metals was studied.The results showed that the concentration sequence of heavy metals in sludge samples is Zn>Cu>Pb>Cd,Which were all in the range of farming standards.Zn,Cu,and Pb existed mainly in the form of residues and organic.Cd existed mainly residues,iron-manganese oxidatio... |
