Effective removal of Amoxicillin, Cephalexin, Tetracycline and Penicillin G from aqueous solutions using activated carbon nanoparticles prepared from vine wood

Tetracycline adsorption by H3PO4-activated carbon produced from apricot nut shells: A batch study

“…The low-cost adsorbent that is produced by raw materials, such as agricultural waste, makes adsorption an operational process. Recent studies of producing adsorbent are sludge-derived adsorbents (Ocampo-Pérez et al, 2012) (Rivera-utrilla et al, 2013a), porous carbon from waste hydro char (Zhu et al, 2014), petroleum coke-derived highly porous activated carbon (D. , FeMn binary oxide (Liu et al, 2012), amino-Fe (III) functionalized SBA15 (Z. , sponge like RCGEM, polyacrylamide cryogels (Ers, 2013) and activated carbon produced from agricultural waste like bamboo charcoal (Liao et al, 2013), macadamia nut shells (Martins et al, 2015) and vine wood (Pouretedal and Sadegh, 2014). In this study, activated carbon was synthesized using hard shell of apricot stone as precursor which was used for TC batch adsorption in aqueous solution.…”

Removal and degradation of β-lactam antibiotics in water using didodecyldimethylammonium bromide-modified montmorillonite organoclay

“…Requirements of high oxidant dosage and pH adjustment (typically pH 2~4) are additional expense for large scale treatment. Activated carbon adsorption has been extensively used in practical water and wastewater treatment processes [11,12] and applied to the removal of a wide range of pharmaceuticals [13][14][15]. However, the extent of removal for β-lactam antibiotics is largely dependent on the kind of antibiotics and often insufficient because of their low hydrophobicity (log Kow = 0.9~2.9 [16]) and negative charge in neutral pH region (pKa ~ 2.7 [16]) [1,15].…”

Role of [FeOx(OH)y] surface sites on the adsorption of β-lactamic antibiotics on Al2O3 supported Fe oxide

“…On the other hand, adsorption has been considered one of the most effective method for antibiotic removal and different materials such as polystyrene resins [11], silica nanospheres [12], zeolite [13], birnessite [14], graphene [15,16] have been investigated. Specifically for the adsorption of ␤-lactam antibiotics several materials such as carbon nanotubes [17], activated carbon [18] and bentonite [19] have been investigated. Microporous activated carbon is likely one of the best cost and efficient alternative for the adsorption of antibiotics [20,21].…”
