青海黄土母质发育的土壤对铬(III)吸附量的初步研究

研究了青海地区黄土母质发育的6类土壤对不同铬(III)标准溶液的吸附特性,并探讨了土壤有机质、阳离子交换量(CEC)、物理性黏粒对铬(III)吸附量的影响。结果表明:6类土壤对铬(III)的吸附率均在90%以上,吸附率最大为99.95%。其吸附率与土壤有机质、CEC呈正相关。

Preliminary studies of Cr(III) absorbing capacity in Qinghai soil of development from loess

The absorbing capacity of six kinds of soil development from loess parent material in Qinghai was studied by using of Cr(III) stardard solution and the effects of soil organic matter,cation exchange capacity(CEC) and physical clay on the absorbing capacity of Cr(III).Results showed:all the soil absorbing capacity was above 90 percent,the maximum absorbing capacity was 99.95 percent.It had positive correlation with soil organic matter and CEC.
