【摘要】：为探究无机盐离子对长焰煤吸附苯胺效果的影响,分别在去离子水、添加氯化钠和添加氯化钙环境中进行了吸附条件实验,并对吸附过程进行了热力学和动力学研究。吸附试验表明添加无机盐可以明显提高长焰煤对苯胺的吸附,且添加Ca Cl2时效果更好。在3种不同环境中长焰煤对苯胺的吸附过程均符合拟二级动力学模型。最后,通过动电位试验和溶液化学分析探讨了无机盐促进长焰煤对苯胺吸附的影响机理。
[Abstract]:In order to investigate the effect of inorganic salt ions on the adsorption of aniline by long flame coal, the adsorption conditions of aniline were studied in deionized water, sodium chloride and calcium chloride, respectively. The adsorption process of aniline was studied by thermodynamics and kinetics. The adsorption test showed that the addition of inorganic salt could obviously improve the adsorption of aniline to long flame coal. The adsorption process of aniline by long flame coal in three different environments is in accordance with the pseudo-second-order kinetic model. The effect of inorganic salts on the adsorption of aniline by long flame coal was studied by potentiodynamic test and solution chemical analysis.
