Modification of Fly Ash and Treatment of Hypersaline Aniline Wastewater
摘要
Abstract
Fly ash was modified using HCl and H2SO4 as modifiers.The modification conditions optimized through orthogonal tests are as follows:V(HCl) ∶ V(H2SO4)=1 ∶ 5,soaking time 6 h,activation time 6 h and activation temperature 250 ℃.When the initial aniline mass concentration is 200 mg/L,the NaC1 mass fraction is 15% and the adsorption time is 60 min,the adsorption capacity of the modified fly ash to aniline can reach 4.16 mg/g.The adsorption of aniline on the modified fly ash is fit better for Freundlich equation.关键词
