Two simple and sensitive spectrofluorimetric methods have been developed for the determination of labetalol (LBT). In method A, the native fluorescence was measured at 432 nm after excitation at 312 nm. The second method (method B) is based on the formation of a ternary complex between zinc (II), eosin and LBT. The fluorescence intensity of the ternary complex was measured at 452 nm after excit...

Metal ions can exist in several forms. Ion-exchange plays an important role in modern analytical chemistry. Transition metals can be separated using either anion or cation exchange chromatography, depending on the choice of complexing agent used in the eluent. Iron deficiency is the most common of nutritional anemia in human beings. It is also an essential component of myoglobin, cytochomes, ca...

Diclofenac, a non-steroidal anti-inflammatory drug, is prescribed to reduce inflammation and as an analgesic reducing pain in certain conditions. In this study, a sensitive reaction system for quantitative determination of diclofenac was introduced. The method is based on the catalytic effect of diclofenac on the Orange G-bromate reaction system. The change in absorbance was followed spectropho...

A rapid and highly sensitive flow-injection chemiluminometric method was developed for determination of 3 sympathomimetic drugs, namely, etilefrine hydrochloride, isoxsuprine hydrochloride, and prenalterol hydrochloride. The method is based on chemiluminescence induced by oxidation of drugs with acidified potassium permanganate in the presence of formic acid as a carrier. The calibration graphs...

A simple, sensitive, selective rapid spectrophotometric method has been developed for the determination of synthetic antimicrobial furazolidone in pure form and pharmaceutical formulations based on the oxidative coupling reaction with MBTH reagent, at P4.0 which is extractable at 630 nm. Beer’s law is obeyed in the concentration ranges 10-60 μg ml. And 5-30 μg ml. For blood sample the developed...

Highly sensitive, selective, rapid and economical Electroanalytical technique, Differential Pulse Polorography is developed for the determination of cobalt using newly synthesized complexing agent, 4-2-hydroxy phenyl ethaminodiol benzene-1,3-diol (4-2-HPEDB-1,3,D). At pH 5.5 a calibration graph was constructed in the concentration range of 0.1 to 200 g/mL with correlation coefficient 0.9998. T...

ABSTRACT A simple, economical, accurate, precise and reproducible UV-Visible spectrophotometric method for the routine estimation of dasatinib has been developed. The method is based on the formation of a bluish green colored complex by dasatinib in presence of MBTH reagent. The developed colored complex showed λmax at 630 nm. Beer’s law in the concentration range of 10 to 60 μg/ ml. Results of...

A spectrophotometric method using flow injection analysis (FIA) is described for the determination of amoxicillin (AMX). Its detection limit, linearity and reproducibility were examined.The automated method is based on a coupling reaction between AMX and diazotized paranitroaniline (DPNA) in alkaline medium to form an intense reddishorange, water-soluble dye that is stable and has a maximum abs...
