Low cost agricultural waste material and animal bones were utilized for the preparation of activated carbon. Industrial spent carbon was also regenerated. The carbon samples were activated chemically and by thermal means (400-1000°C). The samples were characterized by surface area (BET, DR, BJH, Langmuir) with pore volume, FTIR, XRD, SEM and EDS. The rate of adsorption of dyes on the carbon samples was high in the initial fifteen seconds and then declined due to its diffusion in to the micropores. Negative values of entropy of activation ( S) of the dyes adsorption reflected the affinity of the dye molecules towards the carbon surface which were found to decrease with the increase in adsorption temperature. The linear plots of Bangham and intraparticle diffusion models showed that the adsorption of dye on the carbon surface is a diffusion controlled process. The Freundlich, Langmuir and DR models were used to estimate the adsorption parameters. The best fit of the isotherms, found from the correlation coefficients (r2) were in the sequence: DR Langmuir Freundlich.

Activated carbons are unique and versatile adsorbents because of their extended interparticulate large surface area, microporous structure, high adsorption capacity and high degree of surface reactivity. Depending on the functional group and ions present on the surface of the activated carbon, its adsorption quality varies. However, high cost and non-renewable source of commercially available Activated Carbons limits its use as an adsorbent. This has led to the search for low cost feedstock as raw materials for the synthesis of activated carbons. Activated carbons prepared from locally available biowaste such as the stem and leaves of common bamboo and common Buckwheat have been successfully demonstrated for the removal of lead and Manganese ions from water.

This book is more suitable for undergraduate and postgraduate students who are interested in research. This illustrates how waste plastic materials such as polyethylene, polypropylene, polystyrene and polyethylene terephthalate could be converted into low-emissive and low-cost hydrocarbon fuel by two process namely vacuum and catalytic cracking (activated carbon, activated carbon with granulated charcoal and activated carbon with calcium oxide). Hydrocarbon molecules from the materials are split under the impact of catalyst inside the reactor in 70-240 degree Celsius. The various analyses done for the oil are also discussed and concluded that it can be used as a viable and alternative motor fuel. The properties of the oil is very similar to the properties of diesel. Hence it can be used as low-cost and alternative fuel for compression ignition engines.

ggf. zzgl. Versand

Water pollution is a serious threat to mankind in the present scenario and, hence, many techniques are in use for water treatment. Out of them the adsorption is a commonly used method as it is simple, fast, and universal in nature. Typically, activated carbon is used as a perfect adsorbent for wastewater treatment but it is overpriced and requires regeneration. The regenerated carbon exhibits lower adsorption capacity with further management problem of the effluent obtained from its regeneration. These facts have grown interest in the search for solid waste based low cost alternatives of activated carbon that can be used for water pollutant removal. This book tells how (i) to develop low cost adsorbents from waste materials (ii) to remove toxic pollutants by using developed low cost adsorbents (iii) to optimize adsorption parameters for the maximum removal of pollutants by using developed low cost adsorbent through batch process (iv) to transfer batch adsorption conditions to the column studies, to evaluate the feasibility of the developed adsorption system in real samples (v) to ascertain adsorption mechanism for applying the developed adsorption system effectively & practically.

In this study the potential of household waste charcoal has been determined as low cost adsorbent for the removal of heavy metals (lead (II) and silver (I)) from the industrial effluents with a double objective of solid waste management for improved treatment of waste water. The household waste activated charcoal and zero valent iron nano-particle doped household waste activated charcoal is synthesized and checked for its removal efficacy for heavy metals lead and silver in laboratory and is characterized using FT-IR, powdered XRD and AFM analysis. The comparison of the affecting parameters has shown that prepared simple household waste activated charcoal without zero valent iron nano-particles doping showed the removal for Lead 79.11% and for Silver 75.21%. While in case of zero valent iron nano-particles doped household waste activated charcoal was found quite effective in removing 92% Lead (II) and 89% Silver (I) from the simulated samples. This study indicated that zero valent iron nano-particles doped household waste activated charcoal can be used as an effective, low cost and environment friendly adsorbent for the treatment of tannery and battery manufacturing waste water.
