【摘要】 本文以黄棕壤为对象,探讨了植酸对土壤被镉污染的解吸影响及解吸过程。结果表明,在植酸的作用下,黄棕壤中镉的解吸量明显增加,对镉的吸附-解吸过程较易发生,镉在自然环境中的可流动性加快。植酸的添加,为研究土壤中加速重金属的去除,为镉在环境中的迁移转化和治理技术等方面的实际应用提供了有价值的参考。更多还原

【Abstract】 In this paper,yellow brown soil is used to research the effect and process of phytic acid on desorption to soils contaminated by cadmium.The result shows that in yellow brown soil,the existence of phytic acid increases desorption of cadmium significantly,turns the process of absorption and desorption easier,and speeds up the flowability of cadmium in natural environment.Adding phytic acid to soil provides a valuable reference for research of heavy metals removal from soil and practical application of cadmium migration in the environment as well as its control technology.更多还原
