“…The linear form of the model is given in equation 11 (11) Where, q D is the theoretical saturation capacity (mg/g), B is a constant related to the mean free energy of adsorption per mole of the adsorbate (mol 2 /J 2 ). The plot of lnq e versus ɛ 2 .gives a straight line, where B and q D can be calculated from the slope and intercept of the plot.…”

“…The reports in literature have shown that over 735 tonnes of synthetic dyes are produced worldwide, annually with 10-15 % of the dyes being lost in the effluent during the dyeing processes [1]. To overcome this predicament, several researchers have sourced for low cost , non conventional materials for adsorbent; coconut shell [2] scolymus hispanicus L: [3] bean husk [4] globe artichoke leaves [5] rice husk [6] bone [7] snail shell [8] corncob [9] chicken waste and coal [10].Molasse [11] palm flower [12] palm kernel shell [13] rice husk and sugar cane baggasse [14] olive stone [15] paper mill sludge [16] and waste tire [17].…”

Research Article AJCR 2017 1:4 Evaluation of cassava (Manihot Esculentum) seed waste Activated carbon for kinetic study on methylene blue dye adsorption from aqueous solution The effect of activation temperature on activated carbon was studied at 400o C, 500oC and 600oC respectively. The characterization properties showed that increased in temperature reduces yield, moisture content, ash content and volatile content but increased fixed carbon, pore volume and porosity. Batch experiment was conducted by varying the dosage of activated carbon (0.2g-0.6g) and contact time (40-120 min) on adsorption of methylene blue dye from aqueous solution. The experimental data was fitted to pseudo first and second order kinetics in order to verify the rate controlling mechanism. The pseudo second order model showed a better fit with the highest correlation coefficient of 0.998. The adsorption capacity q computed was found to be 6.561 mg/g and 16.129 mg/g showed deviation from the experimental value of 11.00 mg/g for the both kinetics. The equilibrated isotherm data was also fitted to Langmuir, Freundlich and Dabinin-Radushkevich. Freundlich model has the best fit with R2 = 0.914. The energy of adsorption was calculated using the Dabinin-Radushkevich model and found to be 5.89 kJ/ mol.

“…Rajeshwar Man Shrestha 10 suggested different activated carbons prepared by variable parameters with optimal conditions like Lapsi seed stone particles to Phosphoric acid ratio (1:1), temperature of carbonization (400 o C), and time required for carbonization (4 hours). The utilization of cheaper wastes and agricultural by-products like apricot stones 11 , guava seeds 12 , black stone cherries 13 , peach stones 14,15 , orange peel 16 , Peanut shell 17 , coconut shell and wood 18 , rubber seeds 19 , molasses 20 are used for the preparation of activated carbon. Commercial activated carbons are commonly produced from naturally occurring carbonaceous materials such as coal, wood, and peat 21 .…”

Activated wood charcoal (Carbonized) acts as an excellent adsorbent and it finds wide applications. The present study was carried on four different activated wood charcoals Salix (Sac), Pinus (Pac), Anacardium occidentale (AOac) and Calophyllum inophyllum (CIac) found in Karwar district, Karnataka, India. The activated charcoal was prepared by carbonizing in a muffle-furnace at 800 0 C and the yield of carbonized carbon was about 50%. SEM morphology and EDX spectrum indicates the homogeneity and purity of the activated wood charcoals containing 65-86% carbon to that of commercial charcoal (89% C) and hydrogen is absent. Langmuir and Freundlich adsorption isotherms are well-correlated and verified. The regressive coefficient (R2 ) of isotherms recorded a higher value above 0.92 which proves the homogeneous and even adsorption phenomenon by the activated wood charcoals. Sac and AOac recorded highest percentage of removal of acetic acid of about 40-60% and 20-26% with Cac (20-25%) where Pac and CIac recorded 17-23% which is relatively near to the commercially activated charcoal(Cac). On comparison of relative percentage of removal of acetic by activated wood charcoals with commercial charcoal, the activated wood charcoals serve as an efficient adsorbent for acetic acid. The cost and availability of the wood is cheaper.

“…Consequently, a wide variety of agricultural by-products and wastes has been investigated as cellulosic precursors for the production of activated carbon in addition to hard wood and bituminous coal. These precursors include: coconut shell and wood (Laine et al, 1989), Olive stones (Rodrigues-Reinoso et al, 2001, Lafi 2001, Elsheikh et al, 2003, sugarcane bagasse (Ahmedna et al, 2000), pecan shells (Shawabkeh et al, 1998), palm seed (Rengaraj et al, 2002), apple pulp , rubber seeds (Rengarag et al, 1996) and molasses (Legrouri et al, 2005). Furthermore, more interest has been devoted to utilize some wastes of carbonaceous materials such as paper mill sludge (Khalili et al, 2000), old newspaper (Okada et al, 2003) and waste tires (Rozada et al, 2005).…”

-In this study, activated sludge was used as a precursor to prepare activated carbon using sulfuric acid as a chemical activation agent. The effect of preparation conditions on the produced activated carbon characteristics as an adsorbent was investigated. The results indicate that the produced activated carbon has a highly porous structure and a specific surface area of 580 m 2 /g. The FT-IR analysis depicts the presence of a variety of functional groups which explain its improved adsorption behavior against pesticides. The XRD analysis reveals that the produced activated carbon has low content of inorganic constituents compared with the precursor. The adsorption isotherm data were fitted to three adsorption isotherm models and found to closely fit the BET model with R 2 equal 0.948 at pH 3, indicating a multilayer of pesticide adsorption. The maximum loading capacity of the produced activated carbon was 110 mg pesticides/g adsorbent and was obtained at this pH value. This maximum loading was found experimentally to steeply decrease as the solution pH increases. The obtained results show that activated sludge is a promising low cost precursor for the production of activated carbon.
