| Abstract: | This paper
reports the sorption study of Direct Yellow12 (DY) to describe the suitability
of low cost adsorbents prepared from sugar mill waste bagasse, rice mill waste
rice husk and textile industry waste cloths for its effective removal. The
adsorption studies have been performed by varying parameters such as adsorbent
dosage, pH of the dye solution,
contact time and temperature. A significant increase in percentage removal of
DY with increase in dosage of all the carbons is observed. The maximum removal
of dye is obtained under acidic conditions, in particular, at pH 4. The equilibrium adsorption data
obtained are used to calculate Freundlich and Langmuir isotherms and
thermodynamic parameters such as ∆Go, ∆Ho, ∆So,
Ea and S* are calculated in order to understand the nature of
sorption process. The sorption process is found to be controlled by
pseudo-second-order and pore diffusion models. |
