Effect of the adsorbent dosage, initial dye concentration and contact time on methyl orange dye removal by napier grass stem treated with hexadecyl trimethyl ammonium bromide (CTAB)

The use of the inexpensive and environmentally friendly adsorbent Napier grass has been suggested in the current study as a substitute for the expensive techniques now in use for adsorbing methyl orange dye from aqueous solution. FTIR analysis was used to examine the properties of modified Napier grass both before and after adsorption. To determine the ideal experimental circumstances, a variety of factors, including adsorbent dosage, initial dye concentration, and contact time, were examined. The ideal parameters for dye removal are 1 g of adsorbent dosed for 120 minutes at a dye concentration of 50 mg/L. Napier grass stem were treated with CTAB to enhance its ability to adsorb the Methyl Orange dye.
