【摘要】：為探究無機鹽離子對長焰煤吸附苯胺效果的影響,分別在去離子水、添加氯化鈉和添加氯化鈣環(huán)境中進行了吸附條件實驗,并對吸附過程進行了熱力學(xué)和動力學(xué)研究。吸附試驗表明添加無機鹽可以明顯提高長焰煤對苯胺的吸附,且添加Ca Cl2時效果更好。在3種不同環(huán)境中長焰煤對苯胺的吸附過程均符合擬二級動力學(xué)模型。最后,通過動電位試驗和溶液化學(xué)分析探討了無機鹽促進長焰煤對苯胺吸附的影響機理。
[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.
