Trapping synthetic dye molecules using modified lemon grass adsorbent

Physicochemical method was used to prepare lemongrass leaf activated carbon (LLAC) for removal of Remazol brilliant violet 5 R (RBV5R) dye from aqueous solutions. The surface area, mesopore surface area, total pore volume and average pore diameter of the LLAC are 836.04 m2/g, 598.6 04 m2/g, 0.472 04 cm3/g and 3.62 nm, respectively. The surface functional groups of LLAC before adsorption showed the existence of C–H, O–H, C-O, C = O, C = C, CH3,...
