摘　　要：用振荡平衡法研究了西宁地区栗钙土对Cr(VI)的吸附。结果表明:栗钙土对Cr(VI)有明显的吸附作用,酸度和交换剂对栗钙土吸附Cr(VI)均有影响。随着pH值升高,吸附量下降,pH升高到一定时,吸附量不在有所变化。在吸附铬中,残渣态铬占吸附铬的含量最高,碳酸盐态铬占吸附铬的含量次之,有机态铬占吸附铬的含量较低,离子交换态铬占吸附铬的含量最低。The absorption behavior of chestnut soil in X.ining area to Cr（VI） was studied with the vibration zero-method.The result showed that the chestnut soil had the obvious absorption to Cr（VI）, the acidity and the exchange medicinal preparation influenced greatly this absorption. The grality of absorption was descended along with the increase of pH, and that won not change when pH reached to certain extent, Among absorption Cr（VI）, the residual condition content was the highest, the carbonate condition content was second,the organic condition was lower, and the ionic exchange condition was the lowest.
