ADSORPTION OF SYNTHETIC DYES ON POLYVINYL ALCOHOL GRAFTED CARBON NANOTUBE/ OIL PALM EMPTY FRUIT BUNCH HYDROGEL IN AQUEOUS SOLUTION

The research of hydrogels is recently becoming more focus of researchers in sequestration of removing dye. However, the hydrogel structure’s is not rigid and strong enough to sustain for regeneration process. Synthetic polymer hydrogel for dye removal application face low adsorption efficiency and weak mechanical strength.
