以某市为例,在野外采样和实验室分析的基础上,探讨 pH 对土壤吸附重金属镉的影响.结果表明,不同土壤对镉的吸附能力不同(水稻土>紫色土>红壤),改变土壤的 pH 可以降低土壤对镉的吸附.研究土壤中的重金属对农业生产非常重要.

With the example of a city, we study the effect of pH on adsorption of heavy metal Cadmium in the soil based on the outside investigation and laboratory analysis. The results show that the different soil has the different adsorption capacity(Paddy soil>Purple soil>Red soil), and it can reduce the adsorption of cadmium by changing the soil pH. It is important for the agricultural production to study the heavy metal in the soil.
