Dyeing of cotton fabric using pomegranate (Punica granatum) aqueous extract.

Abstract: The decline in the use of artificial colourants due to their toxicity in food and textile industry, put forward by international market has increased the importance of natural raw materials. From those, pomegranate peel (Punica grantum) with solid applications is one of the most important sources of natural dyes. The major colouring component in pomegranate is tannins, extracted from the fresh and dried peels. The aim of present work is to evaluate pomegranate powder as natural textile dyestuff. The work consists of three steps, i.e. extraction, characterization and dyeing processes. The dye extraction procedure is conventional and traditional. Dyeing of different textiles, synthetic and natural fabrics with the extract of pomegranate powder has been carried out and dyeing has been optimized. Finally, dyed fabric have been subjected to different textile laboratory tests e.g., colour fastness, light fastness, washing fastness and rubbing fastness (dry and wet).

Adsorption Studies on the Removal of Hexavalent Chromium-Contaminated Wastewater using Activated Carbon and Bentonite

Abstract: In this study, the adsorption potential of activate d carbon and bentonite for removal of Cr(VI) ions f rom wastewater has been investigated. The study involves batch type ex periments to investigate the effects of initial con centration, adsorbent dose, agitation speed, contact time, temperature an d pH of solution on adsorption process and the eval uation of optimum conditions. The adsorption process has fit pseudo-second order kinetic models. Langmuir and Freundlich adsorption isotherm models were applied to analyze adsorption data, and both were found to be applicable to this adsorption process. Thermodynamic parameters, e.g., ∆G ◦ , ∆S ◦ and ∆H ◦ of the on-going adsorption process have also been calculated and found the sorption process as endothermic. Finally, it can be seen that bentonite was found to be more effective for the removal of Cr(VI) than activated carbon, under the same experi mental conditions.

An overview on biofuels and their advantages and disadvantages

Abstract: Blazing of fossil energy resources generally changes the global climate. Speeding up of global temperate nowadays is an important aspect. Emission of greenhouse gases mainly from blazing of fossil energy resources is one of the most important sources. So, to carry the significant energy and to reduce air pollution, biofuels might be a substitute energy sources. The unnecessary utilization of fossil energy resources or fuels results deficient in the storage in underground earth then people naturally have to depend on biofuels. Consequently increasing demand for the manufacture of biofuels will put a huge burden on agriculture and food prices. Biofuels generally attributed as liquid fuels which are made from the biomass. This consists of mostly wood, vegetable oils, forestry products, agricultural crops, agricultural residues or municipal garbage, residues of domestic animal wastes and aquatic plants. In this review, we summarized the different types of biofuels including biodiesel and their comparative study, production and uses from an ecological perspective.
