Book excerpt: Aims of this research project was to add value to largely wasted South African sawdust by development of low-cost AC of high efficiency for removal of toxic Cr (VI), phenol and glutaraldehyde from dilute aqueous media. The main objectives of the research project were: a) To develop low-cost AC based on South African P. patula sawdust using economical physical superheated steam activation.Characterization of carbon samples for selection of optimum preparation conditions for development of low-cost AC of effective microporosity mesoporosity and surface functionality for enhanced adsorption capacity of Cr (VI) and/or phenol and/or glutaraldehyde from dilute aqueous solution. Acid-amine surface groups modification of optimally developed AC for further enhancement of adsorption capacity for mixed polarized glutaraldehyde molecules from aqueous solution. b) To evaluate the aqueous phase batch adsorption properties of developed AC for Cr (VI) and phenol and, of acid-amine modified developed AC for glutaraldehyde. Determination of optimum pH for adsorption; accurate adsorption isotherm modelling for determination of maximum adsorption capacity, comparison of maximum adsorption capacities for Cr (VI) and phenol of developed AC with commercial AC and literature ACs, and attempt to establish average micropore size for enhanced capacity for Cr (VI) and phenol from dilute aqueous solution.Kinetics reaction and diffusion modelling for determination of adsorption rate constants and diffusion parameters; and determination of adsorption thermodynamic parameters.Evaluation of equilibrium selectivity of developed AC for Cr (VI) and/or phenol in binary aqueous solutions. c) To evaluate aqueous phase fixed-bed adsorption characteristics of developed AC for single Cr (VI) and mixed solution using Rapid Small Scale column Tests (RSSCTs). Generation of breakthrough curves at optimum adsorption conditions for evaluation of column performance indicators at different process conditions, bed regeneration-reusability potential, and dynamic adsorption selectivity of developed AC for Cr (VI) from solution of base metals. Determination of column diffusion parameters; accurate mass transfer and empirical modelling of breakthrough data; determination of applicable RSSCT scaling equation; and optimization of breakthrough data for accurate RSSCT scale-up.

Available in PDF, EPUB and Kindle. Book excerpt: Studies were undertaken of the adsorption of chlorinated phenols from aqueous solution on granular activated carbon (Filtrasorb-400, 30x40 mesh). Single-component equilibrium adsorption data on the eight compounds in two concentration ranges at pH 7.0 fit the Langmuir equation better than the Freundlich equation. The adsorptive capacities at pH 7.0 increase from pentachiorophenol to trichiorophenols and are fairly constant from trichiorophenols to monochlorophenols. Equilibrium studies were performed at various temperatures at pH 7.0. The adsorption process was found to be exothermic for pentachiorophenol and 2,4,6-trichiorophenol, and endothermic for 2,4-dichlorophenol and 4-chlorophenol. Equilibrium measurements were also conducted for 2,4,5-trichiorophenol, 2,4-dichlorophenol, and 4-chlorophenol over a wide pH range. A surface complexation model was proposed to describe the effect of pH on adsorption equilibria of chlorophenols on activated carbon. Activated carbon surface functional sites are divided into acidic groups and basic groups with which molecular and ionized forms of chiorophenols interact, respectively, to form two neutral surface complexes, of which the complex of basic groups is more substantial and more stable than that of acidic groups. The simulations of the model are in excellent agreement with the experimental data. Batch kinetics studies were conducted of the adsorption of chlorinated phenols on granular activated carbon. The external film diffusion model, linear-driving-force approximation, and surface reaction kinetics model were employed to fit the adsorption kinetics data of chlorophenols. The results show that the surface reaction model best describes both the short-term and long-term kinetics, while the external film diffusion model describes the short-term kinetics data very well and the linear-driving-force approximation improved its performance for the long-term kinetics. The mass transfer coefficient was found to increase from more chlorinated compounds to less chlorinated compounds. Two-component adsorption kinetics experiments revealed that the adsorption of chlorophenols on activated carbon is to some extent an irreversible process and non-ideal competition between two components exists. Multicomponent adsorption equilibria of chiorophenols on granular activated carbon was investigated in the micromolar equilibrium concentration range. The Langmuir competitive and Ideal Adsorbed Solution (IAS) models were tested for their performances on the three binary systems of pentachlorophenol/2,4,6-trichlorophenol, 2,4,6-trichlorophenol/2,4-dichlorophenol, and 2,4-dichlorophenol/4-chlorophenol, and the tertiary system of 2,4,6-trichlorophenol/2,4-dichlorophenol/4-chlorophenol, and found to fail to predict the two-component adsorption equilibria of the former two binary systems and the tertiary system. A new prediction method and a modification of the IAS model, both based on thermodynamic considerations, were proposed. The required parameters are the single-component Langmuir isotherm constants and initial concentrations for each component The proposed new method and the modification of the IAS model were found to significantly improve the accuracy of the predictions of two-component adsorption equilibria of chlorophenols. This new method also performs much better than the Langmuir competitive and IAS models in the three-component system. Studies were also conducted on the desorption equilibria and kinetics of chlorophenols. The results indicate that the Langmuir equation fits both adsorption and desorption equilibrium data better than the Freundlich equation and the degree of the irreversibility of adsorption increases from 4-chlorophenol to pentachlorophenol. A linear-driving-force desorption rate equation was proposed, which describes the desorption kinetic data very well. The desorption mass transfer coefficients were found to increase from pentachiorophenol to 4-chlorophenol.
