Chemical forms of Pb, Zn and Cu in the sediment profiles

The chemical forms of heavy metals (Pb, Zn and Cu) in sediment cores of the Pearl River Estuary were studied using a sequential chemical extraction method. The isotope ratios of 206Pb/207Pb in various chemical fractions were also measured to assess the potential Pb sources. Zinc and Cu were mainly a

Role of microbial inoculation and chitosan in

Compared with microbial inoculation alone, chitosan application did not affect plant growth but increased shoot Zn, Pb and Cd concentrations except Cu, which led to higher phytoextraction efficiencies and partitioning to shoots of Zn, Pb and Cd. These results indicated synergistic effects between microbial inocula and chitosan on Zn, Pb and Cd

因此,研究城市表层土壤重金属污染具有重要的现实意义。. 本论文以兰州城市表层土壤为研究对象,测定了其磁化率、重金属Cu、Zn、Pb的含量和TCLP (Toxicity characteristic leaching procedure)提取量,研究了兰州城市表层土壤重金属Cu、Zn、Pb的分布及磁化率特征。. 结果

Removal of Pb, Cu, Cd, and Zn Present in Aqueous

The removal kinetics for Pb, Cu, Cd, and Zn are presented in Table 1 and are fitted to a pseudo-first-order model, and the equation describing this is where is the rate of removal of heavy metal ions (mg l −1), is the electrocoagulation time in hours, and is the rate constant (h −1) . The removal results obtained by electrocoagulation in

Solubility control of Cu, Zn, Cd and Pb in contaminated soils

2005-8-10  An attempt was made from separate published data to correlate total soluble Cu, Zn, Cd and Pb in soils to soil pH, organic matter content and total metal content. For Cu, the total Cu content of the soil was most highly correlated with total soluble Cu. Similarly, total soluble Zn and Cd were correlated with total metal content, but were more

Pollution, fractionation, and mobility of Pb, Cd, Cu, and Zn

However, there were significant differences in fraction distributions of heavy metals in garden and paddy soils. The residual fractions of heavy metals were the predominant form with 43.0% for Pb, 32.3% for Cd, 33.5% for Cu, and 44.2% for Zn in garden soil, while 51.6% for Pb, 40.4% for Cd, 40.3% for Cu, and 40.9% for Zn in paddy soil.
