元素提取器周围土壤的pH值变化

电提取过程依赖直流电场的作用,直流电场持续作用导致土壤介质pH值的变化,当这种变化达到一定程度,又将对电提取过程产生不利影响。因此,它们之间相互关系的研究是电提取方法应该面对的课题。本文通过实际试验数据,揭示和反映了电提取过程中元素提取器周围土壤pH值变化的强度和范围,为上述问题研究提供了初步资料依据。

VARIATION OF pH VALUES IN SOILS AROUND THE ELEMENT EXTRACTORIVER

The process of element extraction depends on the action of the direct current field. The continuous action of the direct current field leads to the variation of pH values of soil media. When such variation reaches a certain degree, it will unfavorably affect the electric extraction process. Therefore, the relationship between them is a subject which ought to be dealt with in future. Based on experimental data obtained, this paper has revealed the intensity and range of pH variation in soil media around the element extractor in the process of electric extraction, thus providing preliminary data for the study of the above problem.
