Nanocomposite Hydrogels for Water Purification
Abstract: DNA hydrogels have been demonstrated as versatile catalysts, potential adsorbents, sensors and immobilization carriers of bioactive molecules. They are a type of tenuous, semiflexible polymeric network that consists of precisely designed synthetic nucleotide strands as chemical or physical cross-linkers. Hydrogels have been widely studied due to their improved physicochemical properties and used as antibacterial platforms, wastewater pollutants, adsorbents and drug deliverers. Because of their biocompatibility and the ability to mix …

Photo-Catalytic Degradation of Dyes Using Graphene Oxide–Dithizone Composite
Abstract: Graphene oxide–dithizone (GO–DTZ) composite was successfully synthesized through the copolymerization of graphene oxide and dithizone to develop an efficient photocatalytic material for wastewater treatment. The dithizone polymer was prepared using a 1:2 molar ratio, while graphene oxide was synthesized via the modified Hummers’ method to obtain highly oxidized graphene sheets with abundant oxygen-containing functional groups. The GO–DTZ nanocomposite was fabricated by ultrasonically dispersing graphene oxide with the synthesized dithizone polymer …

Treatment of Dyeing Waste Water by Using Garlic Extract as a Natural Coagulant
Abstract: Coagulation is the process of removal of very fine particles by forming bigger flocs in the water. But this process is not much efficient in waste water treatment as in the treatment of drinking water. This is because of adding chemical coagulant for the treatment of waste water. Use of chemicals in treatment of dyeing waste water causes formation of non-biodegradable sludge. To avoid this we made an attempt in …

Synthesis and Characterization of Poly(vinylpyrrolidone) / Starch / Dimethylacrylamide Hydrogel by Gamma Radiation and Its Application in Basic Fuchsin and Methyl Orange Removal
Abstract: Gamma radiation was used to create a number of PVP/Starch/Dimethylacrylamide (PSD) based hydrogels. Investigated were the effects of several parameters, such as radiation dose, material composition, and pH, on the characteristics of hydrogels, such as gel content and swelling behavior. Radiation doses ranged from 10 to 25 kGy, and 10 kGy was determined to be the ideal dose. Investigations on the impact of dimethylacrylamide (DMA) composition on swelling were investigated. …

Activated Carbon from Rice Husk for Treating Dye Waste Water
Abstract: This study was undertaken to explore the possibility of utilizing rice husk (RH) for the production of activated carbon because of its abundant, renewable, and biodegradable raw resource, and properties such as its chemical stability, oil absorption, surface area, iodine value, and high reactivity, resulting from the presence of chemically reactive hydroxyl groups. RH is roasted at high % with low cost chemical as catalyst to reduce time, with temperature …

Effective Utilization of Agricultural Waste for Removal of Heavy Metals from Waste Streams
Abstract: The progress of industrialization and urbanization poses a great threat to the comfort of people's lives. The production and disposal of large amounts of toxic pollutants have severely polluted our environment. The most hazardous contaminants in soils and surface waters include some organic compounds, like synthetic dyes (SD) and toxic substances (heavy metals). It is of great interest worldwide due to its toxicity to many organisms. An important topic is …

Desizing of Cotton Fabrics With Enzymes for Improved Performance
Abstract: Desizing of cotton substrates with Amylase enzymes has been practiced since long time and is commercially successful. Amylases convert the water insoluble starches, used during sizing operation for enhancing the performance of the warp yarns, into water soluble products which are removed during subsequent washing. The use of enzymes for desizing is quite safe for the cotton substrates and do not cause any detrimental effect on the cotton cellulose unlike …

In Vitro Evaluation of Bioremediation Capacity of a Commercial Probiotic, Bacillus clausii, for Chromium (VI) and Lead (II) Toxicity
Abstract: Heavy metals cause disastrous effects on any living organisms. Probiotics have the ability to reduce metal toxicity. Commercial probiotics having bioremediation capacity can use these bacteria as an alternative to conventional remediation methods. The bioaccumulation of heavy metals including chromium (VI) (Cr [VI]) and lead (II) (Pb [II]) causes fatal toxicity in humans. Some naturally occurring bacterial species, such as Bacillus and Pseudomonas, contribute their role in bioremediation of these …
