- 实验结果表明,PSN树脂对 (NH4)2SO4的吸附是以分子吸附形式进行,常温下PSN树脂对与自身结构相似的 (NH4)2SO4饱和吸附量可达3.16mmol/g干树脂,吸附等温线符合Langmuir等温方程。The results showed that the inorganic electrolyte molecules were adsorbed by PSN resin and the saturated adsorption capacity was 3.16mmol/g dry resin. The adsorption equilibrium of (NH4)2SO4 by PSN was corresponded to Langmuir equation.
