Abstract

In the current work the methylene blue removal using leaf powder of Alstonia Scholaris was investigated. Pseudo first order, second order and Elovic model ware applied, it has been observed that the adsorption follows second order kinetic model. The isotherm study was done by using Langmuir, Temkin and Freundlich isotherm, the Freundlich isotherm was best suited for present investigation. The maximum adsorption was observed at pH 7.5.
