Tea Waste Impregnated with Iron Oxide Nanoparticles for Dye Removal from Aqueous Solutions
Textile dyes in wastewater can be removed by several techniques, including adsorption. In this study, batch experiments were conducted to determine the possibility of the removal of Basic Red 18 (BR18) textile dye from aqueous solutions using Magnetic Nanoparticles Loaded Tea Waste (MNLTW). The effects of various parameters for the adsorption process such as adsorbent dosage, solution pH, initial dye concentration and contact time were studied under room temperature. The highest dye uptake of 39.56 mg/g was obtained for a BR18 dye concentration of 100 ppm, 250 ml solution and 0.4 g adsorbent dosage. Kinetic data were mostly suited with pseudo-second order kinetic model. The equilibrium data were well fitted by Freundlich isotherm model. Experimental results indicated that MNLTW is a potential substance that can be used for the removal of BR18 dye from wastewater.
