Abstract

Oxidizing and/or reducing agents inversely influence the alterations in the speed of mass changes (dw/dt) due to osmotic perturbations: an oxidizing agent increases while a reducing agent decreases it. The values for isotonic concentration (Ciso) increased for all of the tested non-electrolytes in the presence of an oxidizing agent, while decreased in the presence of a reducing one. The Staverman's reflection coefficient values (sigma) showed changes opposite in direction, so that the direct correlation between the size of test molecules and sigma values remained unchanged. An oxidizing agent increases and a reducing agent decreases the equivalent pore radius (EPR).

摘要

氧化和/或还原剂会对因渗透扰动引起的质量变化速度(dw/dt)的改变产生相反影响:氧化剂会使其增加,而还原剂会使其降低。在有氧化剂存在的情况下,所有测试的非电解质的等渗浓度(Ciso)值都增加了,而在有还原剂存在的情况下则降低了。施塔弗曼反射系数值(sigma)显示出方向相反的变化,因此测试分子大小与sigma值之间的直接相关性保持不变。氧化剂会增加而还原剂会减小等效孔径半径(EPR)。
