含双酚酸聚芳醚砜对水中铅离子的动态吸附
Dynamic adsorption of lead ions in water by poly (arylene ether sulfone) containing bisphenol
摘要
Abstract
The lead ions in the water were fixed bed adsorption using poly (arylene ether sulfone) containing bisphenol.The influence of initial concentration ,volume flow ,initial pH and adsorbent mass on the breakthrough curves was discussed.The dynamic adsorption properties of the polymer adsorbent for lead ions in water were studied by Yoon-Nelson model and Thomas model. The adsorbent after using was regenerated by 0.2 mol/L hydrochloric acid for multiple cycles of adsorption.The results showed that poly aryl ether can effectively remove the lead ion in water ,and the solution flow rate and concentration has a great influence on the outflow curve.The saturated adsorption capacity increased with the initial concentration increasing ,and decreased with the flow velocity increasing.The linear correlation coefficient is 0.94-0.98 ,indicating the Yoon-Nelson model and Thomas model could describe the traditional curve.关键词
