Heavy metal pollution is a worldwide and stringent concern following many decades of industrialization intensive mining without (in some cases) consideration for environmental protection. This review aims to identify the existing emerging techniques heavy metals (HM) removal/recycling from water wastewater, with an emphasis on cobalt.

Thus, several methods applicable were evaluated best treatment approaches cobalt-polluted wastewater.

For each one, depending frequency use, physicochemical mechanisms optimal operational identified carry out successful removal recovery aqueous environments.

Photocatalysis is a prominent alternative wastewater treatment technique that has the potential to completely degrade pesticides as well other persistent organic pollutants, leading detoxification of and thus paving way for its efficient reuse. In addition more conventional photocatalysts (e.g., TiO2, ZnO, etc.) utilize only UV light activation, interest scientific community recently focused on development application visible light-activated like g-C3N4. However, some disadvantages g-C3N4, such high recombination rate photogenerated charges, limit utility. this light, present study focuses synthesis WO3 fibers/g-C3N4 Z-scheme heterojunctions improve efficiency g-C3N4 towards photocatalytic removal widely used insecticide clothianidin. The effect two different precursors (urea thiourea) fiber content properties synthesized composite materials was also investigated. All aforementioned were characterized by number techniques (XRD, SEM-EDS, ATR-FTIR, Raman spectroscopy, DRS, etc.). According results, mixing 6.5% W/W fibers with either urea or thiourea derived significantly increased activity resulting composites compared precursor materials. order further elucidate most photocatalyst in degradation clothianidin, generated transformation products tentatively identified through UHPLC tandem high-resolution mass spectroscopy. Finally, process assessed combining results an in-vitro methodology predictions in-silico tools.

With the development of industry, agriculture, and aquaculture, excessive ammonia nitrogen mainly involving ionic (NH4+) molecular (NH3) has inevitable access to aquatic environment, posing a severe threat water safety. Photocatalytic technology shows great advantages for removal, such as its efficiency, reusability, low cost, environmental friendliness. In this study, CP (g-C3N4/CoP) composite materials, which exhibited high-efficiency were synthesized through simple self-assembly method. For optimal CP-10 (10% CoP) samples, removal rate reached up 94.8% within 80 min under visible light illumination. addition, selectivity S(N2) is about 60% all oxidative products. The high performance photocatalysts can be ascribed effective separation transmission electron–hole pairs caused by their heterogeneous structure. This research significance application photocatalysis remediation wastewater.
