Abstract

A rapid method for indirect assessment of heavy metal mobility based on measurements of specific electric conductivity of soil in model experiments with predefined parameters and a homogeneous medium has been proposed. A strong correlation between the specific electric conductivity values obtained by direct measurements of the soil’s electric resistance and the values obtained with an instrumental method of quantitative element analysis was established. The sorbent showed the highest efficiency towards cadmium; the degree of cadmium sorption being as high as 61.6% at a component ratio of 1 : 3 (sapropel to lime). An efficient sorbent for lead contained the same components at a 1 : 1 ratio and absorbed 14.3% of the ions, and the best ratio for zinc sorption was 1 : 5 (6.4% of ions sorbed).

研究重金属污染土壤中吸附剂的新方法学方法

摘要

提出了一种基于模型中具有预定参数和均质介质的土壤比电导率测量方法来间接评估重金属迁移率的快速方法。在通过直接测量土壤电阻获得的比电导率值与通过定量元素分析的仪器方法获得的值之间建立了很强的相关性。吸附剂显示出最高的镉吸附效率；组分比例为1：3（腐殖酸与石灰）时，镉的吸附度高达61.6％。铅的有效吸附剂以1：1的比例包含相同的成分，并吸收了14.3％的离子，锌的最佳吸附比例为1：5（吸附的离子为6.4％）。
