Removal of Oxytetracycline by Polymers. An Overview

Abstract

Oxytetracycline (OTC) is an antibiotic belonging to the tetracycline family, widely used in veterinary medicine due to its pharmacological characteristics and adequate cost/effectiveness ratio. One of the problems presented by the therapeutic use of antibiotics such as OTC is that they do not metabolize and are expelled through animal excretions reaching the effluent of wastewater, rivers, and lagoons, causing accumulation and generating resistance to certain pathogens, mainly zoonotic bacteria. The above has presented the need and the challenge of removing this type of contaminants present in aquatic systems, using more efficient economic and ecofriendly methods than the conventional ones already known. A promising alternative is removal by using polymeric materials. Therefore, the aim of this revision is give a general revision of the application of functional polymer materials to remove these emerging organic contaminants OTC.

Removal of Amoxicillin Through Different Methods, Emphasizing Removal by Biopolymers and Its Derivatives. An Overview

“…A very wide variety of antibiotic removal has been reported using different types of polymers and biopolymers [114,[211][212][213][214][215][216][217][218], among which we find removal of tetracyclines [112,113,219] and oxytetracyclines [114], ciprofloxacin [220], sulfamethoxazole [221], metronidazole [222], chloramphenicol [223], penicillin [224], amikacin [225], amoxicillin [59,125], among other antibiotics.…”

Recent Advances in Using Adsorbent Derived from Agricultural Waste for Antibiotics and Non-Steroidal Anti-Inflammatory Wastewater Treatment: A Review

“…According to Patel et al [105], hydrogen bond formation between antibiotic molecules and carbonyl groups of banana peel biochar played a significant part in the adsorption process. Additionally, a previous study reported the elimination of antibiotics through dipole interactions [106]. For example, in a recent study by Liu et al [107], the authors highlighted that the oxygen-containing functional groups on the corn stover-based adsorbent surface, such as COOH, OH, and ether groups, could interact with carbonyl and hydroxyl groups of the naproxen via dipole-dipole interaction.…”

Removal of Antibiotic Emerging Pollutants: An Overview

“…2) that confers rigidity. Fuoco (2012) [21] reported that tetracyclines inhibit protein synthesis in bacteria by the amino group at position C4 (antibacterial activity) and ketophenolic tautomers at positions C1 and C3 of ring A [22]. Fig.…”

“…These interactions are the main mechanisms in retention processes, including i) electrostatic interactions, the main retention mechanism in most materials reported in the literature; ii) hydrophobic interactions; iii) hydrogen bonds; iv)𝜋-𝜋 interactions; and v) the morphology of the materials. In specific cases, the pore content [22,[128][129][130][131] would also be considered. Fig.…”
