Flow-injection determination of sulphonamides with fluorimetric or photochemical-fluorimetric detection

Flow Injection On-line Photochemical Reaction Coupled to Spectrofluorimetry for the Determination of Sulfamethazine Using Sodium Sulfite as Sensitizing Reagent

“…The detection limit, linear range of the calibration curve, precision, and sampling rate of the present system are significantly improved in comparison to the previous reported FI-PF method (6). Compared to the recently developed batch-wise room-temperature photochemical reaction system (7), not only the above mentioned analytical performances are better than the batch-wise method, but also organic solvent are absolutely excluded in the present system, resulting in significant reduction of the analytical cost and the risk of environmental pollution.…”

“…A mono-channel manifold, similar to that used by Mahegero et al (6), was first adopted in the present work. Satisfactory fluorescence signals were obtained when a sample solution with moderate concentration of SMT was injected into a carrier solution containing sodium sulfite.…”

“…While exposed to UV irradiation, the drug might also be derived into a intensively fluorescent compound by photochemical reaction (6). Based on the photochemical behavior, Mahedero et al (6) developed a flow injection photochemically induced fluorescence method for determination of SMT in pharmaceutical preparations.…”

Determination of sulphathiazole and sulphanilamide by photochemically induced fluorescence and first-derivative fluorescence

“…Another techniques employed are spectrophotometry [6,12,13] with flow-injection analysis (FIA) [14] and fluorescence [15] with flow-injection analysis [16].…”

Flow injection analysis of the insecticide imidacloprid in water samples with photochemically induced fluorescence detection

“…Photochemical reactions in flow-based methodologies have enabled improvements in the fluorescence detection of selected light-sensitive compounds [21][22][23]. A multi-commutated flow network is another tool to improve versatility, design and sample volumes to be used [24].…”
