“…The mean percentage recoveries were of ) as a function of scan rate. [22], 1.143-142.90 μg mL -1 [23], and 1.8-35.3 μg mL -1 [24], and electrochemical methods for epinephrine: 3.0-175.0 μmol L −1 [26], and 1.0 × 10 −5 to 1.0 × 10 −3 mol L −1 [29]. The regression parameters were computed and presented in Table 1.…”

“…This allows the local anesthetic to persist at the injection site before being absorbed into the systemic circulation [4]. Literature survey reveals that several different analytical techniques have been developed for the determination of articaine HCl and epinephrine including high performance liquid chromatographic methods [5][6][7], thin layer chromatographic methods [8], gas chromatographic methods [9] and spectrophotometric methods [10] for articaine HCl and high performance liquid chromatographic methods [11][12][13][14][15], thin layer chromatographic methods [16,17], gas chromatographic methods [18,19], spectrophotometric methods [20][21][22][23][24] and electrochemical methods [25][26][27][28][29][30] for epinephrine. Carbon based electrodes are currently in widespread use in electroanalytical chemistry, because of their broad potential window, low cost, rich surface chemistry, low background current and chemical inertness.…”

“…Solute concentrations were determined in the permeate and feed samples using a UV-Vis spectrophotometer (UV-1700 PharmaSpec, Shimadzu, Japan), according to each toxin's wavelength of maximum absorbance, λmax: 200, 230, and 293 nm for urea [40], creatinine [41], and uric acid [42], respectively.…”

“…EPN has been determined by several methods, such as liquid chromatography, 8 chemiluminescence, 9 and spectrophotometry. 10,11 From a theoretical standpoint, this paper is concerned with the latter method, accounting for the solvatochromic effects on the UV−vis absorption spectra of EPN in aqueous media.…”

“…EPN was first synthesized in 1904 and displays vast clinical uses, including the treatment of myocardial infarction, bronchial asthma, hypertension, and cardiac surgery. Accurate detection of EPN in biological samples is important for both clinical diagnoses and pathological studies of some diseases. EPN has been determined by several methods, such as liquid chromatography, chemiluminescence, and spectrophotometry. , From a theoretical standpoint, this paper is concerned with the latter method, accounting for the solvatochromic effects on the UV–vis absorption spectra of EPN in aqueous media.…”
