One-step Sb(III) decontamination using a bifunctional photoelectrochemical filter

Capacity of Nerium oleander to Phytoremediate Sb-Contaminated Soils Assisted by Organic Acids and Oxygen Nanobubbles

“…Specifically, trivalent compounds of antimony have been found to be more toxic (10 times) than the pentavalent ones [ 5 ]. Sb removal from environmental water bodies has received a great deal of attention in the last decades; therefore, technologies such as coagulation, adsorption, and the electrochemical method have been widely tested and found to be effective [ 6 , 7 , 8 ]. However, the main disadvantages of these methods are the use of chemicals, the high energy consumption, and the risk of secondary pollution; hence, the efficient removal of the antimony compounds from the environment remains a challenge [ 9 ].…”

Enhanced electro-peroxymonosulfate activation using a carbon nanotube filter with a functionalized polyelectrolyte

“…[21][22][23] Guo et al 24 reported that a flow-through electroactive carbon nanotube (CNT) membrane exhibited a 20-fold enhancement in organic degradation efficiency compared with a conventional batch system. This promising technology has been demonstrated to be effective in various environmental applications such as detoxification of heavy metal ions, 25,26 mitigation of membrane fouling, and degradation of refractory organic contaminants. 5,[27][28][29] Regarding the electrode materials, CNT is a promising base material for preparing electrodes and membranes with sp 2 -hybridized carbon configuration, outstanding electric conductivity, desirable robustness, and high specific surface area.…”

Photocatalytic Cr(VI) elimination over BUC-21/N-K2Ti4O9 composites: Big differences in performance resulting from small differences in composition

“…Metal-organic frameworks (known as MOFs) and coordination polymers (CPs) are periodic porous materials with ultra-high porosity and are constructed from metal ions or clusters and organic linkers through coordinative bonding interac-tions and self-assembly [13][14][15]. Due to their advantages of various synthesis methods and adjustable active sites, MOFs and CPs are considered star materials and are widely studied in the field of gas adsorption/separation [16][17][18], sensing [19][20][21], catalysis [22][23][24], and absorptive pollutant removal applications [25].…”
