Removal of tetracycline from aqueous solution by a Fe3O4 incorporated PAN electrospun nanofiber mat

Enhanced dechlorination of 2,4-dichlorophenol by recoverable Ni/Fe–Fe 3 O 4 nanocomposites

“…Because nZVI accounted for the major part of the nanocomposites, the peak of Fe 0 (2θ of 44.9°), and the peaks of nFe 3 O 4 (2θ of 31, 36, 43, 57, and 62.5°) were relatively small. This phenomenon was in agreement with other reports (Liu et al, 2015;Xu et al, 2013a). Also, in this study the peak of Ni 0 was not observed, which indicated that Ni and Fe formed an amorphous alloy.…”

Environmental implications and applications of engineered nanoscale magnetite and its hybrid nanocomposites: A review of recent literature

“…A novel adsorbent, Fe3O4 incorporated polyacrylonitrile nanofiber mat (Fe-NFM) is able to remove tetracycline (TC), a typical class of antibiotics, from aqueous solution. Compared to conventional NP adsorbents which have difficulties in downstream separation, the novel nanofiber mat can be simply installed as a modular compartment and easily separated from the aqueous medium, promising its potential in drinking and wastewater treatment for micro-pollutant removal [251,252]. Four types of organic acid-functionalized (oleic, undecenoic , caprylic or hexanoic acid) MNPs have been tested to remove TC from aqueous solution.…”

“…According to the literature, the pH is the most important parameter since it affects dissolution within aqueous solution. Tetracycline is an amphoteric molecule and it can be cationic (H3TC + , pH 3.30), zwitterionic (H2TC, pH 3.30-7.68) and anionic form (HTC − and TC2 − , pH 7.68) (Figueroa, Leonard, & MacKay, 2004;Liu, Zheng, Zhong, & Cheng, 2015). When the effect of pH on tetracycline adsorption by ptPO was examined, it is said that the adsorption amount was increased when pH value of the tetracycline solution was increased from 3 to 5 (Figure 3.a).…”

“…might have been effective in the adsorption. According to the recent studies about removal of tetracycline, the highest adsorption amounts were observed when the acidic pH values were applied (Kang, Liu, Zheng, Qu, & Chen, 2011;Zhu et al, 2014;Liu et al, 2015). The temperature is also one of the most effective parameters in adsorption experiments.…”
