摘要：The Activated carbon, obtained from local paper industry, has been used as an inexpensive and effective adsorbent for the removal of colour from pulp and paper industry. Effect of various operating variables, viz., contact time, initial concentration, adsorbent dose and particle size on the removal of colour has been studied and discussed. It is found that for optimum removal of colour, contact time for adsorption equilibrium equals to 60 min., at dosage of 2 g/L of Activated carbon. The material exhibits good removal capacity (97%) and follows both the Langmuir and the Freundlich models.
