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 …

Thermogravimetic Study Of Chrysodine Dye Type Bridge Containing Bis (8-quinolinol)s Ligands and Their Coordination Polymers
Abstract: Our thermogravimetric analysis state that the degradation in chrysodine dye type bridge containing bis (8-quinolinol)s metal coordination polymers was initiated at almost the same temperature near about 25-500 C(T0). The remarkable difference is observed in the mode of thermal degradation of the parent ligand and its coordination polymer. The unchelated bis(8-quinolinol) ligand and coordination polymers begin to decompose almost at the same temperature but in the polymer chelates this decomposition …

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 …
