花生壳活性炭对水中荧光素钠的吸附及动力学
Adsorption and dynamics of active peanut shell carbon adsorbing fluorescein sodium
摘要
Abstract
Active peanut shell carbon (750℃) as adsorbent, fluorescein sodium as adsorbate, the influences of carbonization temperature, dosage, initial pH , ionic strength, adsorption time, and concentration on adsorption effect were investigated in the test. Focuses on the isothermal adsorption characteristics of the active peanut shell carbon adsorbing fluorescein sodium, the pseudo-first order, pseudo-second order kinetic dynamics models and the particulate interior diffusion equation were used to analyze the dynamic process. The results showed that Langmuir isotherm model can simulate the adsorption effect well, and the adsorption intensity factors (a) were positive, which indicated the spontaneity of adsorption process. By substituting experimental data into dynamic model, the pseudo-second order kinetic dynamic model can better simulate the trend of data.关键词
