Study on Adsorption of Anion -cation Modified Zeolite onto Methyl Orange in Wastewater
摘要
Abstract
The composite modified zeolite of hexadecyl trimethyl ammonium bromide(CTMAB) and sodium dodecyl sulfate(SDS) was adopted to prepare the anion -cation modified zeolite, whose structure is characterized by XRD and IR. Meanwhile, the adsorption property, the influential elements and the adsorption kinetics process of this kind of modified zeolite onto ethyl orange in wastewater is studied. The results showed that the anion - cation modified zeolite,whose adsorption kinetics follows the laws of pseudo -second -order kinetic equation,can greatly improve adsorption ability,adsorption rate and adsorption amount of zeolite onto methyl orange. The relationship between equilibrium adsorption amount (qe) and equilibrium concentration (Ce) also corresponds with Langmuir isothermal adsorption equation.关键词
