The variation in the adsorption capacity
between the various concentrations of
adsorbent is depending on surface area
required for adsorption. With increasing
adsorbent concentration more surface area is
available for the adsorption due to increasing
the active site of adsorbent. After some time
the adsorption was affected due to
equilibrium. The adsorption of dyes
increased with the sorbent dosage and
reached an equilibrium value after 10 g of
sorbent dosage. When the biosolid was
increased from 10 to 12 g, the ratio of dye
sorbed to biomass (mg g-1) showed no
significant change
