Abstract
CONCLUSION The present study shows that some waste biomaterials namely; maize cops, sugarcane stalks, peanut hull and banana peals can be used as adsorbents for the removal of some textile dyes (Maxilon Blue GRL, Maxilon Red GRL and Maxilon Yellow GL) from its aqueous solutions. The amount of dye sorbed was found to vary with initial solution pH, adsorbent dose, and contact time. The amount of dye uptake (mg/g) was found to increase with increase in solution pH and contact time and found to decrease with increase in adsorbent dosage for all dyes onto different adsorbents. The fitting of equilibrium data to different adsorption isotherms were evaluated by Langmuir, Freundlich and Temkin models. The dyes uptake capacities (mg/g) were as follows (depending on Q0 values derived from Langmuir model): i) For Maxilon Blue GRL: BP (38.31) > MC (34.01) > SS (28.09) > PH (12.06) ii) For Maxilon Red GRL: PH (119.17) > MC (66.04) >Bp (45.25) > SS (17.66) iii) For Maxilon Yellow GL: SS (52.08) > BP (15.19) > MC (7.73) > PH (6.59) So, it could be concluded that banana peels is the best adsorbent for Maxilon Blue GRL, while peanut hull is the best adsorbent for Maxilon Red GRL and sugarcane stalks is the most effective adsorbent for Maxilon Yellow GL dye. These agricultural wastes are cheep and could be used as adsorbents for removal of some textile dyes from industrial influents.
