Dyes, which are used in various industries like food, cosmetics, pharmaceutical, textile etc., for various purposes cause diseas
es like causes cancer, kidney failure, dysfunction of brain, infertility etc. In this research paper low cost adsorbent (activated carbon) w
as prepared from date palm trunk fiber by chemical activation using H3PO4 as activating agent. The synthesized activated carbon was
characterized with FTIR spectroscopy. The FTIR result confirms the introduction of various functionalities like alcohol, esters, carbox
ylic acid, benzyl and alkyl functionalities into activated carbon. Crystallinity was checked with XRD pattern, which shows that the acti
vated carbon has amorphous nature which is very suitable for adsorption. Finally it was utilized for the adsorption of Malachite Green
, a model cationic dye, from water. The various parameters studied include adsorbent amount, pH and contact time. The optimum con
ditions determined were adsorbent dosage 0.5g, contact time 20 min and pH5-7. From the result, we conclude that activated carbon of
date fiber remains an efficient adsorbent for removal of Cationic dye and may prove the best low cost adsorbent dye-wastewater treat
ment.
