Abstract: This study was aimed to use Gigantia Leaves (GL), Curcuma Longa Leaves (CLL), Morienga Oleifera (MO) and Citrus Sinensis (CS) as a potential adsorbents to remove C.I. Reactive Blue 82 dye from aqueous solution. The adsorption of Reactive Blue 82 on adsorbents was studied as a functions of dose (50-300 g/L), pH solution (2-12), contact time (30 min). The influence of these parameters on the adsorption capacity was studied using the batch process. The corresponding results showed that excellent colour removal of Reactive Blue 82 can be achieved with adsorbents at optimum pH of 2. The maximum colour of Gigantia Leaves, Curcuma Longa Leaves, Morienga Oleifera and Citrus Sinensis was 90.36%, 80%, 75.81% and 70.90% respectively.The experimental data were analyzed by the Langmuir, Freundlich isotherms, Kinetic studies, and Interruption studies. Results show that the data fitted well with the Freundlich isotherm. The kinetics of Reactive Blue 82 adsorption onto adsorbents was examined using the pseudo-first and pseudo-second order.The adsorption kinetics followed the pseudo-second order kinetic modelwhich implies that chemisorption is the rate limiting step. Pore diffusion seems to be the rate controlling in the sorption process as indicated by interruption studies.
