Preparation of cetyltrimethylammonium bromide modified diatomite for adsorption of Reactive Blue 19 (RB19) from aqueous solution
Abstract
The preparation, and dye adsorption of cetyltrimethylammonium bromide modified diatomite were investigated. The prepared cetyltrimethylammonium bromide modified diatomite was characterized using Fourier transform infrared (FT-IR) spectroscopy and Scanning electron microscope (SEM) techniques. The influences of sorbent dosages, pH, reaction time, reaction temperature in adsorption capacity and adsorption isotherms were studied. The optimum conditions for reactive blue 19 (RB19) adsorption were pH 1.0, contact time of 60 min with 0.5 g of cetyltrimethylammonium bromide modified diatomite. The maximum adsorption rate reached to 98.0%. Langmuir and Freundlich adsorption model were applied to describe the equilibrium isotherms. The equilibrium data were found to be fitted well to both Langmuir and Freundlich isotherm and the maximum adsorption capacity was determined to be 71.9 mg/g. The results suggested that cetyltrimethylammonium bromide modified diatomite was a promising sorbent to remove dyes from textitle wastewater.
