土壤中无机钠盐对不同形态锌离子浓度的影响
Effects of Inorganic Sodium Salt in Soil on Concentration of Zinc Ion in Different Patterns
摘要
Abstract
[Objective]The aim was to study on effects of inorganic sodium salt in soil on concentration of zinc ion in different patterns. [ Method ] Tessier sequential extraction was used to study on effects of inorganic sodium salts which were in different species and different concentrations on concentration of zinc ion in different patterns. [ Result] Different inorganic sodium salts had different effects on zinc form. Content of exchangeable Zn would reduce if Na2CO3 or Na2S04 were added and the content would increase if NaCI was added. Contenl of carbonate line, which was significantly influenced by Na2SO4, would increase if NaCl or Na2S04 was added, and would decrease if Na2CO3 was added. For Zn bound to Fe-Mn oxides and organic matters, and residual Zn, the contents would decrease if NaCl or Na2S04 was added and the decrease showed much more significantly if high concentration sodium salts were added. In addition, content of Zn bound to Fe-Mn oxides decreased if Na2CO3 was added. If low concentration Na2CO3 was added, Zn bound to organic matters and residual would increase in contenl but would lower if high concentration one was added. [ Conclusion] The research provided references for measurement of heavy metal ion contenl in soil in different places.关键词
