A Study on adsorption of Phenol red dye and Chromium (VI) metal ion using activated carbon derived from Lantana camara with the activation of potassium hydroxide.
Abstract: Commercial activated carbons are expensive to produce and regenerate, it is essential to produce activatedcarbon using low-cost raw materials and methods. This study's goal is to demonstrate the possible adsorptionproperties of activated carbon made from Lantana camara for the removal of dyes and metal ions fromaqueous solutions. In this study, activated carbon from Lantana camara stems was obtained through a one-step chemical activation procedure using potassium hydroxide KOH. The surface …

Characterization of Laccase Enzyme from Dye Degrading Bacterial Strains Isolated from Natural Sources
Abstract: The continuous growth in globalization and industrialization has increased the environmental pollution and one such major contaminant is various types of synthetic dyes. Microbial decolorization and degradation of these dyes through secretion of various extracellular enzymes is gaining importance owing to their eco-friendly nature. One such enzyme is laccase, a multicopper oxidase enzyme which has the ability to oxidize both phenolic and non-phenolic compounds through reduction of molecular oxygen to …

Use of Advanced (i.e., Membrane) Technology for the Wastewater Treatment of Coke Ovens
Abstract: Coke plants produce gas, and coke for metallurgical purposes and also supply the raw materials for the manufacture of dyes, drugs, and high explosives. Naturally found coal is converted into coke in coke ovens. A large quantity of water is used for quenching hot coke and for washing gas. After quenching the wastewater contains high-suspended solids, high biochemical oxygen demand (BOD) (600–1300 mg/L), chemical oxygen demand (COD) (1500–3000mg/L), phenols(500–650 mg/L), …
