ISOTHERM MODELLING - ADSORPTION OF N-BLUE DYE IONS ONTOMICRO WAVE ASSISTED PTEROCARPUS MARSUPIUM BARK CARBON

Abstract

An adsorption N-Blue dye ions from aqueous solution on MWPMBC (Micro Wave assisted Pterocarpus Marsupium Bark Carbon) has been investigated. Analytical techniques have been employed to find characteristics of adsorbent materials. The adsorption of N- Blue dye ions was conducted in batch system. The effects of pH, adsorbent dosage and initial concentrations of N- Blue dye ions and contact time on adsorption efficiency were studied. Optimum adsorption was achieved at a pH 3 and equilibrium was established within 70 8 80 min of the process. The equilibrium adsorption data were analysed using four adsorption isotherm models: Langmuir, Freundlich, Temkin, Dubinin-Radushkevich isotherms. It is concluded that MWPMBC can be used as an effective adsorbent for removing N- Blue dye ions from aqueous solution.
