Heavy metal pollution in the aquatic environment: efficient and low-cost removal approaches to eliminate their toxicity: a review

“…91 AOPs such as Fenton, photo-Fenton, and electro-Fenton have also been shown to be effective in removing heavy metal complexes from wastewater due to their ability to generate highly reactive oxidizing species, which can degrade complex organic pollutants and release free heavy metal ions that can be eliminated using conventional treatment methods. 92 On the other hand, the use of natural soil and mineral deposits to remove heavy metals from wastewater appears to be the least effective method, as their adsorption capacity is limited and oen requires large amounts of material for efficient removal. Therefore, the selection of the appropriate treatment technology for heavy metal removal from wastewater depends on several factors such as the type and concentration of heavy metals, the characteristics of the wastewater, and the economic and environmental feasibility of the treatment method.…”

“…This growing popularity is due to advantageous features such as the absence of chemical inputs, short processing time, compatibility for ambient conditions, high energy efficiency, environmental friendliness, and efficient degradation of recalcitrant organic contaminants. 199,200 An investigation was conducted to evaluate the effectiveness of using discharge plasma in combination iron internal microelectrolysis for the decomplexation of Cu-EDTA. 201 The plasma oxidation was effective in destroying EDTA and the presence of iron played a key role in accelerating the decomposition process.…”

Iron-loaded carbon black prepared via chemical vapor deposition as an efficient peroxydisulfate activator for the removal of rhodamine B from water

“…In comparison to alternative treatment methods such as biological treatment, 17 membrane separation, 18 and adsorption, 19 advanced oxidation processes (AOPs) are a promising and efficient water treatment technology for removing emerging organic pollutants via producing reactive oxygen species (ROS). 20,21 The ROS group includes hydroxyl, sulfate, superoxide radicals, and singlet oxygen. ROS may be produced via the activation of peroxymonosulfate (PMS) and peroxydisulfate (PDS) utilizing methods such as heat, UV radiation, metal ions, metal oxides, and so on.…”

Removal of chlorhexidine digluconate from aqueous solution by heterogenous photocatalysis using sunlight-driven Ni-doped TiO2 material

“…Nevertheless, some of their internal limitations including poor visible light consumption, decreased photogenerated electrons and holes pairs separation, and a lack of active species generation hampered their practical uses. Thus, the development of an efficient and new type visible light-driven (VLD) photocatalysts, as well as extensive synthesis and modification methods, are the main challenges in current studies to maximize the exploration of solar light [7,8].…”
