| 摘 要： | 本文针对电提取法时量曲线测量中存在的一些方法技术问题,通过理论与实验研究给出了补液取样和不补液取样的时量曲线浓度校正公式及校正方法;明确了电提取离子含量与供电电量Q＝I·t有关,即由供电电流强度(I)和供电时间(t)的乘积来决定;证实了采用间断供电方式时,只要累积电量与连续供电相等,则其提取结果和时量曲线变化特征将基本一致。

| Abstract: | In view of some technical problems that exist in the measurement of time-extracted quantity curves of the electric extraction method, this paper, based on theoretical and experi-mental research, has worked out formulae of concentration correction and methods of correction for time-extracted quantity curves of sampling with supplementary liquid and without supple mentary liquid, and made clear that the contents of electric extracted ions are related to electric quantity Q = I·t, i. e., determined by the product of intensity of electric current (I) and time of power supply(t). It has been confirmed that, when the style of discontinued power supply is adopted, the extraction results are basically consistent with variation characteristics of time-extracted quantity curves so long as the cumulative electric quantity is equal to the quantity of continuous power supply. |
