Separate and simultaneous removal of doxycycline and oxytetracycline antibiotics by electro-generated adsorbents (EGAs)

Kinetics and isotherms of oxytetracycline adsorption on β‐cyclodextrin/carboxymethylcellulose hydrogel films

“…Table compares the maximum adsorption capacity ( q max ) of various adsorbents reported in literature (Song et al, ; Wang, Xu, Yang, Wang, & Wang, ; Zaidi et al, ; Zhang et al, ; Zhou, Zhu, & Fei, ). β‐CD/CMC is clearly superior to most adsorbents listed in Table .…”

“…Therefore, the adsorption of OTC onto hydrogel films seems a monolayer. The maximum adsorption (Song et al, 2014;Wang, Xu, Yang, Wang, & Wang, 2017;Zaidi et al, 2019;Zhang et al, 2018;Zhou, Zhu, & Fei, 2018). β-CD/CMC is clearly superior to most adsorbents listed in Table 4.…”

Comparative study of BiVO4 and BiVO4/Ag2O regarding their properties and photocatalytic degradation mechanism

“…The photocatalytic degradation pathway of DC includes hydroxylation, demethylation, ring-opening, deamidation and oxidation of -NH 2 . By reviewing some studies, [43][44][45][46] the proposed BiVO 4 /Ag 2 O sample had the character of low size, high activity, simple preparation and environmental friendliness. This study enriched the types of visible light catalysts and provided a reference for the removal of doxycycline in water.…”

Use of alumina sludge arising from an electrocoagulation process as functional mesoporous microcapsules for active corrosion protection of aluminum

“…When aluminum electrodes are used in the electrocoagulation process, various monomeric and/or polymeric metal hydroxides like [Al(OH)] 2+ , [Al(OH)2] + , [Al2(OH)2] + , Al(OH)3, [Al6(OH)15] 3+ , [Al7(OH)17] 4+ , [Al8(OH)20] 4+ , [Al13O4(OH)24] 7+ , [Al13(OH)34] 5+ are produced and they can be involved as electro-generated adsorbents (EGAs) [17,18]. These hydroxides are an effective adsorbent for the removal of different substances present in water whose toxicity is well-known like fluoride anion [12,17,19], heavy metals [20], arsenic [17,19], and pharmaceuticals [21], which precipitate in the reactor as electrocoagulated metal hydroxide sludge (EMHS) including pollutants present in the water. This EMHS can be dangerous for the human health and the environment, so its treatment is an important issue.…”
