Abstract

The present study analyses the feasibility of removing Disperse red 9 (DR9)
from industrial effluents using two different adsorbents namely Phosphoric acid
impregnated Activated Carbon (PAC) and Polypyrrole Polymer Composite (PPC) prepared
from Casuarina wood. Batch mode adsorption studies were performed in order to
investigate the adsorption capacities of these adsorbents by varying initial dye
concentration, agitation time, temperature and pH. A comparative study on the adsorptive
capacities of PAC and PPC were carried out and it was inferred that PPC had better
adsorption capacity than PAC at an initial concentration of 50 mg/L at 300C, 350C & 400C.
The calculated qe values agree very well with experimental values. The regression
coefficient values above 0.98 confirm that adsorption follows second order kinetics. The
increase in Langmuir adsorption capacity (Q0) from 7.48 to 9.41 mg/g for PAC and 8.65 to
11.73 mg/g for PPC on increasing the temperature from 300
to 400C accounts for the
endothermic nature of the process.
