“…However, use of chemicals such as chromium as tanning agents have a lot of negative implications and costly to the environment (Fahim et al, 2006). This chemical accumulates in the environment and may cause carcinogenic effect (Dayan and Paine, 2001) and has currently been implicated as one of the challenges in running leathery industry in developing and developed world (Fahim et al, 2006).On the other hand, application of enzyme in tannery processing is cheaper and has less or no toxic wastes (Aravindhan et al, 2007).…”

Manufacturing industries contribute about 8% of the gross domestic products (GDP) whereas leather and textile industries supply 18% employments of manufacturing industries in Tanzania. Manufacturing industries merely depend on agriculture for raw materials and other inputs. However, processing of leather and textiles requires a lot of inputs, many of them supplied from agricultural produce and some are imported from developed nations. In vast developing countries, including Tanzania, manufacturing industries are constrained by limited production technology and the allied costs than raw materials. The conventional processing of leather and textiles requires immense technological investment that is associated with high production cost. In Tanzania, inputs such as soaking, bating and tanning agents for tannery industries are expensive and sometimes not readily available due to importation costs. On the other hand, management of waste effluents from leather and textile processing is the major impediment for development of these industries. However, natural processing of covering materials by using fungal biotechnology is of great concern in Tanzania to avert the prevailing constrains. The application of fungal based biotechnology would reduce production cost and health consequences resulting from chemicals, particularly, chromium. The effects of toxic chemicals from leather and textile industries would be mitigated by employing non-viable Aspergillus biomass in the industrial processes.

“…Cr 3+ an Ni 2+ kinetics can be explained using speciation diagrams. Fahim et al (2006) To quantify the kinetic aspects of biosorption, mathematical modeling has been used in several studies over the years. To obtain as much information as possible about the Ni 2+ and Cr 3+ biosorption kinetics, we modeled the experimental data obtained by using four theoretical models: pseudo-first-order (Lagergren, 1898), pseudo-second-order (Ho and McKay, 1998), three-stage (Choi et al, 2007), and the intra-particle diffusion model (Ruthven, 1984).…”

-In this work, the biosorption of Cr 3+ and Ni 2+ by Sargassum filipendula pre-treated with CaCl 2 was studied. Kinetic and equilibrium experiments were carried out for mono-and multi-component solutions in a batch reactor at pH 3.0 and 30 ºC. The results from the kinetic experiments showed that Cr 3+ adsorbs slower than Ni 2+ . This behavior was explained by means of a mechanistic analysis, which showed that Cr 3+ uptake presented three adsorption stages, whereas Ni 2+ adsorption presents only two. The mono-component equilibrium data, along with binary kinetic data obtained from mono-component experiments, showed that, although the kinetics for Cr 3+ removal are slower, the biomass had a stronger affinity for this ion. Almost all Ni 2+ is desorbed from the biomass as Cr 3+ adsorbs. The binary equilibrium data also presented this behavior. The binary data was also modeled by using modified forms of the Langmuir, Jain and Snoeyink, and Langmuir-Freundlich isotherms. However, the prediction obtained presented low accuracy. An alternative modeling with artificial neural networks was presented and the results showed that this technique could be a promising tool to represent binary equilibrium data. The main contribution of this work was to obtain experimental data for Cr 3+ /Ni 2+ adsorption, which is a system rarely found in the literature and that provides information that could be used in process modeling and simulation.

“…Carbonaceous materials play an important role not only in a purification of exhausted gases and waste water, but also as catalysts, catalyst supports or reducing agents (MarotoValer et al 2005;Nowicki et al 2012;Fahim et al 2006;Kadirvelu et al 2001;Bashkova et al 2007;Muniz et al 2000;Goscianska et al 2012;Valente et al 2003). Observed in recent years growth in the use of such materials is mainly caused by the relatively low cost of their production, rich resource base, as well as favorable physicochemical properties, such as highly developed surface area, high mechanical strength and chemical resistance and ease of degradation of used material.…”

Preparation and physicochemical characterisation of functionalised multi-walled carbon nanotubes

A series of new functionalised carbonaceous materials were prepared by means of oxidation and ammoxidation of commercially available multi-walled carbon nanotubes. The effect of oxygen and nitrogen doping on the textural, surface as well as thermal properties of the prepared adsorbents was tested. The materials were characterized by elemental analysis, low-temperature nitrogen sorption, determination of the surface oxygen groups content as well as by coupled thermogravimetric and spectroscopic methods (TG/DSC/MS). Depending of the variant of raw nanotubes modification, the final products were oxygen-and nitrogen-doped materials of medium-developed surface area and mesoporous structure, showing highly diverse acidic-basic character of the surface, from the weakly acidic to slightly alkaline.
