Abstract

Cost effective and greener approach for water decontamination is the need of the time.
Present work deals with the batch mode removal of anionic dye (Alizarin Red S) from water using
biological materials Acacia nilotica leaves (KL), Terminalia arjuna nuts (AN) and Berri ptta
capsule (BPC). Various parameters like pH, adsorbent dose, temperature, time were optimized to
further conduct the isothermal, kinetics and thermodynamic studies. Isothermal studies revealed
that qmax values were in the order. AN nuts (52.95 mg/g) > KL (42.546 mg/g) > BPC (40.60 mg/g)
following pseudo second order kinetics model. The process of anionic dye removal is spontaneous
and exothermic in nature. These biological materials proved very useful for water decontamination
and therefore can be used on large scale.
