CONJUGATIVE EFFECT OF LOW COST ADSORBENT WITH LACCASE ENZYME FOR REDUCTION OF PULP AND PAPER EFFLUENT LOAD, ITS KINETICS AND THERMODYNAMICS

Pulp and paper industrial effluent has the foremost role in environmental pollution. The key factor of current study is to determine conjugative effect charcoal (60%) alluvial soil (40%) mixture with laccase enzyme lessen load pulp industry. adsorbent was used for adsorption biological oxygen demand (BOD) chemical (COD), color, lignin effluent. impact pH, temperature, concentration, time on removal procedure were studied. Adsorption equilibrium achieved after 50 minutes an agitation rate 500 rpm at pH 6.0 25 degree. Results indicated that COD, BOD, removed 86%, 80%, 60%, 62% respectively. Moreover, also enhanced reduction these parameters as COD 95%, BOD 93% color 83%, 75%. experimental batch analyzed by Freundlich Langmuir models kinetics discussed pseudo-first-order pseudo-second-order. data fitted pseudo-secondorder kinetic model. Thermodynamics ∆G˚, ∆H˚, ∆S˚ results thatadsorption nonspontaneous due high TDS lignin, endothermic nature, revealed increase randomnessand degree disorderliness during present study. Consequently, use incombination presents promising applicable.
