Adsorption kinetics on basic red 46 removal using Cerbera odollam activated carbon

This paper presents the adsorption study of basic red 46 onto a non-edible sea mango or scientifically known as cerbera odollam. the cerbera odollam activated carbon was produced using chemical activation method using potassium hydroxide (koh) as activating agent. the cerbera odollam activated carbon produced was then characterized using scanning electron microscope (sem) for the analysis of surface morphology and brunauer- emmett-teller (bet) for surface area. it was shown that this activated carbon has developed new pores on its surface and the bet surface area measured was 451.87m2/g. the cerbera odollam activated carbon was further used for adsorption of basic red 46 in batch process. the experimental parameters studied are adsorbent dosage and ph of the solution. it was found that the best ph of solution is at ph 11 and increasing the adsorbent dosage will increase the removal of basic red 46 where the highest is by 1.0 g/l. conducting the kinetic analysis,the experimental data has fitted well on pseudo-second-order kinetic model compared to pseudo-first-order kinetic model. © school of engineering,taylor’s university.
