土壤中游离重金属离子的测定——唐南膜平衡法

MEASURING OF THE CONCENTRATIONS OF FREE HEAVY METAL IONS IN THE SOIL-DONNAN MEMBRANE TECHNIQUE

对比了最近几十年来国内外土壤溶液中游离重金属离子浓度的测定方法,在此基础上建立了一种新的测量方法———唐南膜平衡法(DMT)。研究表明,该实验方法可以在不影响反应体系平衡的基础上同时测定多金属元素,而且彼此之间不会发生干扰。

Some methods of measuring the concentrations of free heavy metal ions were compared, and a new method, Donnan Membrane Technique (DMT), was established. By this method, many metals could be measured at the same time without disturbing the balance of the reaction. Furthermore, all the metals did not interfere each other.
