【摘要】 介绍了铁交联累托石的制备 ,研究了交联累托石对含锌废水的处理。结果表明 :当交联累托石的用量为 1 2g/L废水、pH =4、常温搅拌吸附 90min时 ,Zn2 + 由 12 2 5mg/L降为 0 97mg/L ,达到国标GHZBI 1999地表水质量一级标准。累托石对Zn2 + 吸附符合Freundlich等温吸附 :Γ =0 34C0 492 3 ,动力学试验表明 :吸附反应为一级反应方程 :lnCt=lnC0 -0 340 6t,其相关系数r =0 95 18,试验测得其热力学函数为 :ΔH =1 91kJ/mol,ΔS =6 90J/mol·K ,ΔG =- 0 16kJ/mol,说明该吸附过程可自发进行更多还原

【Abstract】 The method of makind Fe pillared rectories is introduced, and the result of experiment of zinc containing wastewater treatment shows: under the condition that the usage of Fe pillared rectories is 1 2 g/L,average temperature ,stirring absorb 90 min; the concentration of Zn 2+ decreased from 12 5 mg/L to 0 97 mg/L, up to the first standard GHZBI₁999 of surface water quality. The adsorption isotherm was fitted well with the langmuir equation: Γ =0 34 C 0 4923 ,the reaction of adsorption is the first reaction kinetics equation: ln C t =ln C 0 -0 3406 t ,the thermodynamics factors: ΔH =1 91 kJ/mol, ΔS =6 90 J/mol·K, ΔG =-0 16 kJ/mol. It shows the reaction can be proceeded by itself.更多还原
