“…Recently, various flowinjection analysis along with suitable detection technique have also been reported for the determination of PCT. Growing interest in the use of FI in conjunction with UV/vis spectrometric techniques has been demonstrated in several papers [89][90][91][92][93][94][95][96][97][98][99][100]. Existing FIA methods for determining PCT are mostly based on the hydrolysis of paracetamol to p-aminophenol, which is then transformed into a coloured derivative by a suitable reaction.…”

“…É um sistema em fluxo de maior robustez quando comparado com sistemas cromatográficos e de fluxo como aqueles propostos anteriormente [19,23,28]. Apresentou uma curva analítica com uma maior intervalo de concentração quando comparada com outros sistemas de análises por injeção em fluxo para determinação de paracetamol [19,30,32,33] e ainda, apresentou um menor consumo de nitrito por determinação, comparado com procedimentos em batelada [16][17][18][19].…”

“…Diversos sistemas de análise por injeção em fluxo têm sido descritos para determinação de paracetamol em produtos farmacêuticos, empregando detecção: espectrofotométrica [19,[29][30][31][32][33], espectrofluorimé trica [34] e biamperométrica [35].…”

“…Other spectrophotometric flow injection methods based on reaction of paracetamol to produce a indophenol dye [20][21][22][23][24] and systems with solid phase UV spectrophotometric detection [25][26][27][28] have been described for paracetamol determination in pharmaceutical formulations. Flow procedures with chemiluminescence detection were described using luminol based reaction [29,30] and another method employed the oxidation of tris(2,2'-bipyridyl)ruthenium(II) by potassium permanganate [31].…”
