In this work, a novel Fe3O4/graphene oxide (GO) hybrid was prepared and its removal ability of cationic methylene blue dye from water was investigated. To improve the dispersability of Fe3O4/GO hybrid in water, GO was first modified by polyethylene glycol (PEG) via a click approach ...
The present work focuses on the evaluation of selenite removal by applying coagulation/ precipitation with Fe and Al coagulants to a tap water matrix. The criteria of coagulant evaluation were: the ability to achieve residual concentrations (Ce) lower than the current DWRL of 10 µg/L, the ...
The combination of DPAOs and LPT may prove to be a promising approach in bioremediation of eutrophic water. In addition, the activities of urease, invertase, and alkaline phosphatases positively changed with the removal of nitrogen, chemical oxygen demand (COD), and phosphorus correspondingly....
