Abstract
Alstonia Scholaris leaves after treatment with 0.01 M NaOH was used for the adsorptive removal of safranine. As the initial safranine concentration increases from 20 mg/L to 80 mg/L the dye removal increases up to 91 % in 60 min contact time at optimum pH of 8. Pseudo second order model and Freundlich isotherm was followed by the adsorption experimental data.
