Abstract: A Comparative study of low cost adsorbents (Rice husk and Waste activated carbon)
has been made for the colour removal of dye, methylene
blue. The variables studied
are pH, initial dye concentration, adsorbent dose and time. The adsorption follows
first order kinetic
model and rate is mainly controlled by intra particle
diffusion. Freundlich and Langmuir isotherms were fitted
well with the experimental data.
The present study shows that RH may be used as
a better adsorbent than WAC.
Keywords: Dye, Rice husk, Waste activated
carbon, Adsorption isotherms.
