“…Most adsorption methods use a carbonaceous material to trap pollutant molecules inside its pore structure [148,[185][186][187][188][189][190][191][192][193][194][195][196]. While the raw materials for activated carbon can be inexpensive, the energy required to produce high quality activated carbon has been shown to be a significant environmental impact if non-renewable energy sources are used [107,197].…”

“…As the demand for product purity requires ever more sophisticated processes and emission standards become more stringent, activated carbon technology also progresses, the classical granular and powdered forms being supplanted or extended to other forms such as fibres, and fabrics, etc. Monoliths offer the opportunity to adjust the distribution of the porosity or the chemical nature of the surface, or can be impregnated with chemicals to increase the selectivity of substance removal [5,6].…”

Activated carbon monoliths with different surface characteristics were prepared by impregnating oil palm stone with diluted aqueous CaCl 2 solutions (with concentrations between 2 and 7% w/v) without binders. The solids were characterized by determination of nitrogen adsorption isotherms at 77 K and carbon dioxide adsorption isotherms at 273 K using volumetric adsorption equipment. Surface area and micropore volume values were calculated from the nitrogen isotherms using the BET and DR models, respectively, obtaining solids with low percentages of mesoporosity. Immersion enthalpies of the activated carbon monoliths were determined in benzene, with values between -173 and -104 J g -1 , and water, with values between 61 and 30 J g -1 , indicating that the monoliths have a hydrophobic character.

“…There will be no more reduction in COD, after the equilibrium point has reached. Infect at equilibrium the rate of adsorption of pollutant onto the activated carbon is almost equal to the rate of desorption (Mohan et al, 2008). The effect of contact time carried out by using the adsorbent-adsorbate solution with fixed adsorbent dose and initial dye concentration for different time intervals and shaken until equilibrium.…”

In the present review, the suitability of adsorption process using low cost adsorbent for the treatment of pulp and paper mill effluent has been discussed. It is clear that adsorption processes are appropriate for the removal of recalcitrant compounds such as surfactants and pesticides, among others biodegradable or non-biodegradable compound present in pulp and paper mills effluents. The importance of the adsorption is to improvement of the removal of various physico-chemical (biological oxygen demand (BOD), chemical oxygen demand (COD), colour, suspended solids, lignin), heavy metals (Cu, Cr, Fe, Zn, Ni and Mn etc) organochlorine compounds, all recalcitrant pollutant, reduce toxicity, enhance colour removal by using different cost effective adsorbents. The effective use of the different adsorbents developed from different adsorbent media such as activated carbon, agriculture by product and industrial wastes and sludge as adsorbents for the removal of different pollutants from the various processes and operations of pulp and paper mill as potential alternatives to different treatment process and received widespread attention. Adsorption necessity is a novel treatment option to improve the efficiency of removal within the discharge limits of wastewaters into the receiving bodies without causing any damage of the environment. However, still there is a need to find out the practical usefulness of such low cost adsorbent at industrial scale with the special reference to metals.
