Заглавие : Detection of anti-viral drug riamilovir and herbicides in aqueous media by using pyrene-based fluorescent chemosensors Место публикации : Chimica Techno Acta. - 2021. - Vol. 8, № 2. - С. 20218208 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Ключевые слова (''Своб.индексиров.''): covid-19--riamilovir--triazavirin--detection in aqueous media--fluorescence quenching Аннотация: Two ethyleneglycol esters of 1-pyrene carboxylic acid were studied as chemosensors for the fluorescence “turn-off” detection of two nitro-containing analytes, such as antiviral drug Riamilovir (Triazavirin ®) and herbicidal agent dinitro-ortho-cresol (DNOC). In both cases the dramatic fluorescence quenching was observed with quenching constants as high as 3·104 M-1 and limits of detection (LOD) as low as 100 ppb. Доп.точки доступа: Kovalev, I.
