Highly selective water-compatible molecularly imprinted polymers for benzophenone-4

نویسندگان

چکیده

Molecularly imprinting technology was applied for preparing selective sorbents benzophenone-4 (BP4), an organic UV filter used in sunscreens and cosmetics. Several imprinted polymers were prepared by bulk polymerization, using BP4 as template. Combination of stability (mechanical chemical), selectivity robustness the with properties resulted a successful process (imprinting factors range 1.05?2.60). The characterised infrared spectroscopy, elemental analysis, conductometric titrations nitrogen physisorption at 77 K. Adsorption capacities towards 7 other filters (benzophenone-3, benzophenone-8, homosalate, butyl methoxydibenzoylmethane, ethyl hexyl salicylate, p-dimethylamino benzoate p-methoxycinnamate) determined, proving high adsorption capacity binding. highest observed 4-vinylpyridine/ethylene glycol dimethacrylate co-polymer dimethyl sulfoxide (1.108 mmol g-1). polymer binding to solid phase extraction from aqueous solutions 98.5 % efficiency.

Citrinin selective molecularly imprinted polymers for SPE.

Molecularly imprinted polymers (MIPs) for citrinin (Cit) with 1-hydroxy-2-naphthoic acid (HNA) as mimic template were prepared and the molecularly imprinted SPE method was developed for the detection of Cit in rice with HPLC. The adsorption properties of HNA and Cit on the MIPs and nonimprinted polymers were investigated. It proved that MIPs showed higher selectivity adsorption to HNA and Cit t...

Selective Extractions by Molecularly Imprinted Polymers (MIPs)

Sample preparation is often the rate-limiting step in analytical methods and its effectiveness has a critical impact on accuracy, quantification and, ultimately, the precision of any measurement. Traditionally, liquid–liquid extraction methods are frequently used for the extraction of organic analytes from aqueous samples. To overcome some of the disadvantages of liquid–liquid extraction (e.g.,...

Preparation of highly selective solid-phase extractants for Cibacron reactive dyes using molecularly imprinted polymers.

Selective polymeric extractants were prepared for preconcentration of Cibacron reactive red dye, a dye that is often applied with Cibacron reactive blue and Cibacron reactive yellow for dyeing of fabrics. The best extractant was fabricated (in chloroform) using methacrylic acid (as monomer), ethylene glycol dimethacrylate (as crosslinker), AIBN (as initiator for polymerization), and red dye as ...
