Conventional analytical methodologies for the determination of organic contaminants in water matrices are often laborious and time-consuming, require a large amount chemicals. In this study, we have developed green sample preparation approach using Araucaria angustifolia bracts as natural sorbent bar adsorptive microextraction technique. The eight emerging (methyl, propyl, butylparaben, bisphenols A F, estradiol, ethinylestradiol, benzophenone) river-water samples were carried out, employing high-performance liquid chromatography with diode-array detection (HPLC-DAD). Central composite design revealed that best conditions extraction step involved adding 30 % (w/v) NaCl to at pH 6 leaving it 180 min. Simplex-centroid indicated 80 μL mixture acetonitrile (3:1) desorption solvent. Desorption time was univariately evaluated 40 Calibration curves obtained correlation coefficients higher than 0.995. limits quantification range 1 10 µg L−1 inter-day precision from 13 22 %. Relative recoveries two varied 62 116 %, exhibiting relative standard deviations 5 28 which confirmed method's accuracy precision. This method contributes development more environmentally friendly strategies.

Porogenic Solvents in Molecularly Imprinted Polymer Synthesis: A Comprehensive Review of Current Practices and Emerging Trends

Polymers, Год журнала: 2025, Номер 17(8), С. 1057 - 1057

Опубликована: Апрель 14, 2025

The versatility of molecularly imprinted polymers (MIPs) has led to their integration into applications like biosensing, separation, environmental monitoring, and drug delivery technologies. This diversity resulted in a plethora synthesis approaches precisely tailor the materials’ properties specific demands. A critical, yet often overlooked, factor MIP is choice porogen. Porogens play pivotal role defining morphology, surface properties, swelling behavior, binding efficiencies resulting MIPs. While aprotic solvents have traditionally been standard molecular imprinting, recent developments expanded variety employed porogens accompanied by notable improvements performance. Therefore, this review aims highlight both traditional emerging types used influence on polymer sorption performance, application across various sensing extraction applications.
