activated carbon; adsorption; beverages; cetyltrimethylammonium bromide; death; desorption; detection limit; drugs; ethanol; fluorometry; glibenclamide; hydrochloric acid; monitoring; overdose; sedation; suicide; surfactants
Abstract:
... Nowadays, the use of a drug to modify a person's behavior with criminal intentions has become a growing public concern. In fact, stealthy drink spiking with certain drugs can cause the incapacitation of a potential victim of assault and in extreme cases can even lead to death. Belonging to the group of drugs used to commit drug-facilitated crimes is glibenclamide, which not only exhibits high seda ...

Subject:
cetyltrimethylammonium bromide; desorption; detection limit; gas chromatography-mass spectrometry; micelles; microextraction; monitoring; multiresidue analysis; nanowires; pH; pesticides; polymers; river water; scanning electron microscopy; solvents; triazines
Abstract:
... A simple, rapid and sensitive method based on microextraction in packed syringe (MEPS), in combination with gas chromatography–mass spectrometry (GC–MS) was developed. Polyaniline (PANI) nanowires network was synthesized and used as sorbent of MEPS for the multiresidue determination of selected analytes from triazine, organochlrorine and organophosphorous pesticides in aqueous samples. The PANI na ...

Subject:
aquatic environment; carbon nanotubes; cetyltrimethylammonium bromide; desorption; detection limit; diphenylamine; gas chromatography-mass spectrometry; hexane; microextraction; monitoring; nanocomposites; oxidation; pesticide residues; propionic acid; river water; scanning electron microscopy; sulfuric acid; surfactants; triazines; water pollution
Abstract:
... Reinforced polydiphenylamine (PDPA) nanocomposite was synthesized by oxidation of diphenylamine in 4molL⁻¹ sulfuric acid solution containing a fixed amount of carbon nanotubes (CNTs) in the presence of cetyltrimethylammonium bromide (CTAB). The surface characteristic of PDPA and PDPA/CNT nanocomposites was investigated using scanning electron microscopy (SEM). The prepared PDPA/CNT nanocomposite w ...
