响应面法优化锰改性介孔陶粒去除铊废水工艺
Process optimization via response surface methodology for thallium removal wastewater by manganese-modified mesoporous ceramsite
摘要
Abstract
To develop novel adsorbents for treating thallium(Tl)contaminated water,manganese-modified mesoporous ceramsite(Mn@Sic-MC)was prepared and employed as the adsorbent.Single-factor experiments combined with response surface methodology(RSM)were applied to optimize the absorption conditions and to explore the T1-removal mechanism.Under the RSM-optimized parameters(initial pH of 3.8,adsorbent dosage of 53.5 g/L,a contact time of 9.9 h),a Tl removal efficiency of 94.97%was achieved.The adsorption process was well described by the pseudo-second-order kinetic model and the Freundlich isotherm model.Competitive adsorption experiments revealed that,relative to the singleTl system,the removal efficiency of T1 decreased by 16.47%,18.93%,and 7.80%in the TlPb,TlZn,and TlPbZn systems respectively.Nevertheless,a high removal performance was maintained,demonstrating the favorable selective adsorption capability of Mn@SicMC.Desorption-regeneration experiments confirmed the material's recyclability,as the removal efficiency remained above 85%after three cycles,with a material loss rate below 5%.The study provides useful insights for the treatment of heavy-metal-contaminated wastewater.关键词
