REMOVAL OF BISMARK BROWN R DYE FROM AQUEOUS SOLUTION BY LAPLAP PURPUREUS PLANT STEMS UTILIZED AS BIOSORBENT

Abstract

Adsorption of dye utilizing biosorbent is an unusual method to remove the dye from industrial wastewater. Biosorbent arranged from Laplap Purpureus Stem Powder (LPSP) have been utilized as an adsorbent for the removal of Bismark Brown R dye from the aqueous solution. The biosorbent matter was analyzed by Scanning Electron Microscope (SEM) image and Fourier Transfer Infra Red (FTIR) spectroscopy. The batch adsorption experiment studies were carried out to evaluate various adsorbing effect of experimental parameters such as effect of pH, adsorbent dosage, equilibrium time and initial dye concentration. The data obtained from the experimental values were analyzed by Langmuir and Freundlich isotherm model. The adsorption kinetic studies were also analyzed by pseudo first order and pseudo second order models. The result reveals that the removal efficiency of biosorbent (LPSP) is very better for the Bismark Brown R dye from made up aqueous solution.
