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 ,并研究了不同比活度95Zr对土壤吸附比的影响 ,测定了吸附等温线。结果表明 ,95Zr进入淹水土壤后迅速被土壤吸附达到吸附平衡。不同土壤有不同的饱和吸附率 ,海泥 >青紫泥 >小粉土 >黄红壤

摘  要:
The isotopic tracer techniques were used to study the adsorption of 95 Zr in paddy soil on powdery loam,red yellow earth, blue purple clay and sea clay.The results showed that after 95 Zr entered into the flood soil,it was quickly adsorped by soil and reached the adsorption equilibrum.The saturate values of adsorption rate were different with various soils.The order of ability of 95 Zr adsorption was sea clay>blue purple clay>powdery loam>red yellow earth.The different specific activity of 95 Zr on the Zr adsorption ratio with soils and adsorption isotherms of Zr were determined.
