| 摘 要： | 应用同位素示踪技术,研究了95Zr在小粉土、黄红壤、青紫泥和海泥中的吸附。结果表明,95Zr进入淹水土壤之后,将迅速地被土壤吸附而达到吸附平衡。不同土壤有不同的饱和吸附率,就它们吸附95Zr能力来说,海泥>青紫泥>小粉土>黄红壤。还测定了吸附等温线。

| Abstract: | Isotopic tracer techniques were applied to study adsorption of zirconium-95 in different soils including paddy soil on powdery loam, red-yellow earth, paddy soil on blue purple clay and sea clay. The results showed that after zirconium-95 entered into the flood soil, the metal was quickly adsorbed by soil particles and reached the adsorption equilibrium. The saturate degrees of adsorption rate were different with various soils studied. Thus, the rank of the ability of zirconium-95 adsorbed, was found to be: sea clay, paddy soil on blue purple clay, paddy soil on powdery loam, red-yellow earth. The sorption isotherms of zirconium were determined in the present investigation. |
