Summary: The study found that Ga2O3 photocatalyst could effectively degrade Cr(vi) and 6:2 FtS, while In2O3 also showed capability in removing both substances, but at slower rates. On the other hand, poor removal of 6:2 FtS was observed with the TiO2 photocatalyst.

Summary: This research investigates the treatment of phenol wastewater using an electrochemical bromination method. A Ti/Sb-SnO2/PbO2 electrode was used as the anode and the experiments were conducted under different conditions. The results showed that under the best operational conditions, phenol and COD removal efficiencies were 100% and 82.7% respectively. Additionally, the electrochemical bromination method demonstrated high apparent current efficiency and low energy consumption.

Summary: A three-dimensional electrochemical flow-through reactor with GAC packed bed was evaluated for the removal of persistent organic contaminants from real sewage effluent. Results showed enhanced adsorption ability of GAC at high current density, along with a synergistic effect between electrosorption/adsorption on GAC and electrooxidation for the removal of various pollutants. The addition of GAC also decreased concentrations of toxic chlorates and perchlorates, as well as organic iodides and organic chlorines, in the effluent.

Summary: The excessive amount of phenol found in water reservoirs, such as rivers and municipal drains, is a major contributor to the global scarcity of potable water. In recent years, special attention has been given to photocatalytic membranes for the treatment of polluted phenol water. Membrane technology, with its dual function of photocatalysis and sieving, may become a major trend in phenol removal in the future.

Summary: In developing countries with inadequate sewage systems, untreated domestic wastewater is discharged into the environment, leading to worsened environmental pollution. Detergents in domestic wastewater are difficult to manage. This study investigated the effects of the ultraviolet/H2O2 advanced oxidation process on the degradation of linear alkylbenzene sulfonate (LAS), a persistent chemical in detergents.

Summary: The study focused on using a halotolerant strain of the genus Janibacter to remove phenol from saline wastewaters, showing that bacterial cells immobilized on mica and zeolite had higher removal efficiency, better thermostability, wider operating range, and longer reuse potential. The process involved complete destruction of phenol through the meta pathway involving phenol hydroxylase and catechol 2,3-dioxygenase enzymes, with zeolite-immobilized cells showing consistent efficiency even after 4 months of storage at low temperatures.

Summary: This study aimed to improve the adsorption and removal function of attapulgite (ATP) for phenol by synthesizing a cationic surfactant Gemini and modifying ATP. The modified ATP showed better dispersibility and abundant active cationic groups on the surface. The positively charged modified ATP with a hydrophobic surface was able to interact with the phenol molecules through 7C-7C interaction and electrostatic attraction. The adsorption behavior followed the Freundlich isotherm model and the modified ATP showed good reusability.
