Kinetics Study of Methyl Orange Adsorption from Aqueous Solutions using Fly Ash Granules as Low Cost Adsorbent

661-664Fly ash obtained from a thermal power station was granulated using a biopolymer and used as an adsorbent to remove methyl orange (MO) dye from solutions. Uptake of MO from solutions occurred in 30 min of contact and obeyed Langmuir isotherm model. Results point to waste flyash as a promising alternative for removal of azo-dyes such as methyl orange from industrial wastewaters

Bioremediation of Metalliferous Wastes and Products using Inactivated Microbial Biomass

426-443In a developing country like India,. the rush for rapid industrial development coupled with lack of awareness about metal toxicity has become a serious concern to environmentalists. Some technologies, which are used in developed countries for detoxifying metals from industrial effluents, cannot be used in India due to economic constraints. Therefore, there is an urgent need for developing an economical and environment-friendly technology. At the same time, it is essential to prevent the loss of metals through the effluents. The 'Metal Biosorption' process provides a promising alternative method for economical recovery of metals
