High-efficiency solid-phase microextraction performance of polypyrrole enhanced titania nanoparticles for sensitive determination of polar chlorophenols and triclosan in environmental water samples

Abstract

A PPy/TiO2 nanocomposite coating was fabricated by direct electropolymerization of pyrrole on annealed TiO2 nanoparticles and evaluated as a novel direct immersion solid phase microextraction fiber coating for the extraction of trace pollutants in water.

Modern approaches for detection of volatile organic compounds in metabolic studies focusing on pathogenic bacteria: Current state of the art

“…Moreover, Azzollini et al [ 106 ] further demonstrated the antifungal properties of 2-nonanone, as their results clearly indicated that microorganisms triggered a chemical defense in response to the presence of other microorganisms. Researchers continue to develop and refine SPME approaches, both with respect to the employed derivatization strategies [ 107 ] and the novel stationary phases used in the fiber coatings, such as graphene oxide [ 108 ] or its modification with polyaniline/polypyrrole [ 109 ] or polypyrrole-enhanced titania nanoparticles [ 110 ], to improve the method's sensitivity, reproducibility, and linearity range.…”

Enhancing the efficiency of polypyrrole-dodecylbenzene sulfonic acid in-tube solid-phase microextraction coating for analysis of nitrogen-containing pesticides in water environments

“…Polypyrrole (PPy), as a conductive polymer, has shown great potential in the field of SPME due to its unique electronic structure and adsorption properties (Du et al, 2021;Ma et al, 2021). The adsorption capacity of PPy can be significantly enhanced by introducing dopants (Khan et al, 2021;Pal et al, 2023;Yu et al, 2024).…”

Fabrication of a bi-metallic metal organic framework nanocomposite for selective and sensitive detection of triclosan

“…[2][3][4][5] Hence, monitoring TCS levels in hygienic products is of high importance. 6 At present, there are multiple methods such as chromatography techniques, [7][8][9] spectrophotometry, 10 and electrochemical sensors 11 for TCS detection. However, majority of these techniques require experience in handling, large amounts of reagents, and are time-consuming.…”
