Abstract

Dye containing waste water is a major environmental problem .The treatment method for the removal of dye is costly. For this the use of low cost easily available adsorbent was studied. sorption of methylene blue on to groundnut shell was studied by varying the parameters like initial dye concentration, pH and sorbent dosage. Dye biosorption was rapid up to 60 minutes and equilibrium was attained at 240 minutes after 60 minutes the removal rate was slow due to the decrease in the number of vacant sites.

Also the uptake capacity decreases as the amount of sorbent dosage was increased this is due to the increase in the number of solute particles and as the pH varies the is a considerable change in the uptake capacity of the sorbent and all the dyes follow pseudo second order kinetics and also the data fit to Langmuir isotherm very well.
