“…The characteristics of the wool carbonising waste used have been described previously. 1 The elemental analyses of the components of the carbonising waste were carried out in triplicate. The slight decrease in the nitrogen content of the keratin fibres ( Table 1) can be assigned to the peptidic hydrolysis.7-9 The increase in the sulphur content is likely to be a result of the sulphonation of the wool fibres.…”

“…Among these techniques, adsorption is one of the most commonly used methods due to its high efficiency and easy operation (14). In recent years, a number of adsorbents such as iron coated sand, iron coated granular activated carbon (15), modified chitin (16), fly ash (17), low grade bituminous coal (18), wool carbonizing waste (19), rice husk (20), kaolinite (12), Zeolite (21), paper mill sludge (17), bagasse (22), green algae (23,24), bone char (25) and Lignite (26) was used in the heavy metal removal from effluents. In the present work, wheat husk was taken for the preparation of…”

Activated carbon prepared from waste wheat husk was used to remove Ni (II) from aqueous solution by adsorption. Batch adsorption studies were carried out by varying the contact time, initial Ni (II) ion concentration in the aqueous solution, adsorbent dosage, pH and temperature. Maximum adsorption was observed with the pH of 6.0, contact time of 4.0 h, adsorbent 0 dosage of 1.50 g/150 ml and at the temperature of 30 C. It was indicated from the results that the effective removal of Nickel (II) 0 ion was obtained by activating the carbon prepared from wheat husk which was heated to 600 C.Langmuir and Freundlich isotherms were used to describe the equilibrium nature of Ni (II) adsorption. The adsorption capacity (q ) calculated from e Langmuir and Freundlich isotherms were found to be 11.83 mg /g and 11.96 mg/g at pH 6.0 at 303 K. The removal of Ni (II) was found to be 80.1% for the initial Ni (II) concentration of 10 mg/l and adsorbent dosage of 0.50g/150ml. In the isotherm studies, the experimental adsorption data fitted well the Freundlich isotherm for the activated carbon from wheat husk. The results of the thermodynamic investigations indicate that the adsorption reactions are spontaneous (G<0), slightly endothermic (H >0) and irreversible (S>0)

The adsorption of ionic dyes on charred plant material was investigated to assess the possible use of this adsorbent for the processing of dyeworks waste waters. The diffusion of the acid dye (AB 80) within the carbon particles was much slower than that of the basic dye (BR 22), as a result of the greater size of the former molecule. The rate of diffusion of the dyes increased with temperature as a result of the disaggregation of the dye molecules. This effect was more pronounced in the case of the acid dye. The L-shaped adsorption isotherms suggest that the adsorption proceeds through ionic bonding and that the dye molecules are adsorbed flatwise on the surface of the charred plant particles; the substrate-solute hydrophobic interactions can thus be maximum. The charred plant material used is suitable for the processing of low-concentration effluents, as corroborated by the treatment of a BR 22 solution in a series of stirred reactors and by the decolourisation of dyebaths containing acid and basic dyes.
