Batch adsorption studies of chromium(III) onto commercial grade granular activated carbon: Equilibrium and Kinetic Studies
Granular activated carbon, chromium chloride, adsorption capacity, isotherm, kinetics.
Batch adsorption studies were carried out for the removal of chromium using commercial grade granular
activated carbon. Synthetic chromium effluent solutions were prepared using chromium chromium chloride. The effects
of various factors such as pH, agitation rate, and initial concentration were examined. The adsorption capacity was found
to increase with increase in initial concentrations ranging from (300,400,500 mg/l) and was found to be maximum between
the pH ranges 4-5. From the kinetic and isotherm studies Pseudo second order and Langmuir model was found to fit best
with the experimental data’s with R2 values greater than 0.99.The goodness of fit was checked using MATLAB @2009a.
