Catalytic ozonation of pentachlorophenol in aqueous solutions using granular activated carbon

Nitrate Removal from Aqueous Solutions Using Granular Activated Carbon Modified with Iron Nanoparticles (RESEARCH NOTE)

Nitrate contamination of water resources and the growing concentration of nitrate endanger human health and the environment and considering its reduction strategies from water resources is important. The aim of this study was to investigate the possibility of removal of nitrate from aqueous solutions using granular activated carbon from grape wood coated with iron nanoparticles. The results sho...

the study of effective factors in mercury removed from aqueous solutions using granular activated carbon

introduction: wastewaters of chemical, petrochemical, electrical, pharmaceutical and paper industries are the main sources of mercury and its compounds. mercury is one of the toxic elements, so its removal from water and industrial wastewaters seems to be important and essential. the objective of this study was to investigate effective factors such as ph, contact time, absorbent dose, mixing ra...

Removal of copper (II) from aqueous solutions by adsorption onto granular activated carbon in the presence of competitor ions

In this work, the removal of copper from an aqueous solution by granular activated carbon (GAC) in the presence of competitor ions was studied. A batch adsorption was carried out and different parameters such as pH, contact time, initial copper concentration and competitor ions concentration were changed to determine the optimum conditions for adsorption. The optimum pH required for maximum ads...

Comparing activated carbon and magnetic activated carbon in removal of linear alkylbenzene sulfonate from aqueous solution by heterogeneous catalytic ozonation process

Activated carbon from pine cone (PCAC) was used as a precursor to prepare Fe3O4/magnetic activated carbon (MPCAC). Here, the removal of linear alkylbenzene sulfonate (LAS) was studied using catalytic ozonation process (COP) in exposure to MPCAC. Subsequently, it was compared with PCAC. Moreover, the effects of solution's initial pH, catalyst dosage, and the time of ozonati...
