Synthesis and application of molecularly imprinted poly(methacrylic acid)–silica hybrid composite material for selective solid-phase extraction and high-performance liquid chromatography determination of oxytetracycline residues in milk

Characterization of Biochar Derived from Pineapple Peel Waste and Its Application for Sorption of Oxytetracycline from Aqueous Solution

“…Unfortunately, traditional biological treatment methods are ineffective in degrading OTC because of its persistence and recalcitrance caused by its stable naphthalene ring structure (De Liguoro et al 2003;Liu et al 2015). Therefore, even at low concentrations in the environment, OTC is potentially hazardous and toxic to the health and safety of both humans and aquatic ecosystems (Hirsch et al 1999; Sarmah et al 2006;Lv et al 2012;Rizzo et al 2013). It is therefore of the utmost importance to develop more efficient treatment technologies for the removal of this contaminant.…”

Improved selective cholesterol adsorption by molecularly imprinted poly(methacrylic acid)/silica (PMAA–SiO2) hybrid material synthesized with different molar ratios

“…To the best of our knowledge, there are no reports available in the literature on molecularly imprinted hybrid polymers for cholesterol extraction and still few attempts have been made for the preparation of molecularly imprinted polymers selective to the other analytes. A survey of literature demonstrates that molecularly imprinted poly{(methacrylamide)-co-(vinyl trimethoxysilane)} and poly{(methacrylic acid)-co-(vinyl trimethoxysilane)} for caffeine extraction [23] and more recently, molecularly imprinted poly(methacrylic acid)/silica hybrid material have been reported for the selective extraction of lincomycin in aqueous medium and oxytetracycline in milk samples [7,24].…”

“…Furthermore, when exposed to different organic solvents, they may shrink or swell, thereby also causing considerable deformations of MIP receptors and decreasing the recognition ability toward the template [7][8][9][10][11][12].…”

“…Such Materials Science and Engineering C 44 (2014) 99-108 hybrid organic-inorganic polymers have been synthesized by combination of random free-radical polymerization followed by sol-gel process. The symbiosis of organic and inorganic compounds has led to the formation of materials with complementary properties not found in single substances [7]. Apart from the selective feature, very similar to natural recognition systems such as enzyme-substrate and antibody-antigen, hybrid organic-inorganic polymers have even greater advantages, including high physical and chemical stability, and can be employed in the presence of organic solvents under severe pH conditions, where biomolecules cannot be used due to applying some restrictions in aqueous media to them and requiring special storage conditions [17].…”

Recent Advances and Uses of Monolithic Columns for the Analysis of Residues and Contaminants in Food

“…Modern trends in sample preparation for food applications include the use of on-line solid phase extraction (SPE) methods or the use of more SPE-based selective approaches, such as molecularly-imprinted polymers (MIPs) [4][5][6].…”
