4-chlorophenol removal from water using graphite and graphene oxides as photocatalysts
Graphite and graphene oxides have been studied amply in the last decade, due to their diverse properties and possible applications. Recently, their functionality as photocatalytic materials in water splitting was reported. Research in these materials is increasing due to their band gap values around 1.8-4 eV, and therefore, these are comparable with other photocatalysts currently used in hetero...
متن کاملElimination of 4-chlorophenol from Water Solutions Using Commercial Peroxidases
A comparative study of the two most widely used commercial peroxidases (E.C. 1.11.1.7) for removing 4-chlorophenol from aqueous industrial effluents is presented. Both the peroxidases tested, horseradish peroxidase (HRP) and soybean peroxidase (SBP), showed maximal removal efficiency in a neutral pH medium although they maintained more than 70 % of their activity in a pH range of between 6.0 an...
متن کاملNanodiamonds as photocatalysts for reduction of water and graphene oxide.
Detonated nanodiamonds (NDs) exhibit remarkable photocatalytic activity towards the hydrogen gas generation upon 532 nm laser pulse irradiation. Hydrogenation dramatically increases the quantum yield, suggesting that hydrogen-terminated sites work as electron reservoirs. NDs can also be used as effective photocatalysts to reduce graphene oxide. The resulting composites exhibit high and stable p...
متن کاملRemoval of 4-Chlorophenol from Contaminated Water Using Activated Carbon from Dried Date Pits: Equilibrium, Kinetics, and Thermodynamics Analyses
Five different activated carbons (ACs) have been prepared from dried date pits using air and phosphoric acid as activating agents. The used phosphoric acid:date pit ratio dictated the characteristics of the prepared ACs; the equivalent BET-nitrogen surface area varied from 794 m²/g for a ratio of 5:1, to 1707 m²/g for a ratio of 2:1, whereas the micropore volume changed in value from 0.24 cm³/g...
متن کاملApplication of Azolla for 2-Chlorophenol and 4-Chrorophenol Removal from Aqueous Solutions
Background and purpose: The 2-chlorophenol (2-CP) and 4-chlorophenol (4-CP) are phenolic compounds which may have adverse effects on human and environment. Therefore, removing these compounds from water and wastewater is necessary. This study aims to analyze 2-CP and 4-CP removal by using Azolla filiculoides biomass. Materials & Methods: Azolla biomass was sun dried, crushed and sieved to parti...
