安徽凤阳几种土壤对锌的吸附

研究了凤阳县几种土壤吸附锌的性能,讨论了这几种土壤对锌的吸附性能与它们的理化性质的关系。结果表明:供试土壤吸附锌的能力比较接近,土壤吸附锌的量随平衡液浓度的增加而增加,吸附符合Freund lich吸附、Langmu ir吸附和Temk in吸附关系;在土壤质地比较接近的情况下,土壤对锌的最大吸附量与土壤的酸碱度、有机质含量、质地等因素有关。

Zinc Adsorption Properties on Some Soils in Fengyang County

We studied the zinc adsorption properties on some soils sampled from Fengyang county,and discussed the relationship between the adsorption character and soil basic properties.The results showed that the Zn adsorption oapability of soil samples were close to each other,i.e.with the increase of zinc content,the quantity of zinc adsorbed increased.The adsorption fits with the Freundlich equation,Langmuir equation and Temkin equation.When the soils had similar texture,the maximum adsorption amounts of zinc was related to soil pH value,organic matter and clay.
