The present study investigates the use of defatted algal biomass (DAB) as a non-conventional low cost
adsorbent. The maximum adsorption capacity of biomass (raw, defatted and sulfuric acid pretreated
DAB) was determined by liquid phase adsorption studies in batch mode for the removal of methylene
blue present at various concentrations (1, 2, 3, 4, and 5 mg L1
) from aqueous solutions.
