Spectrophotometric determination of quinolone antibiotics by an association complex formation with aluminum(III) and erythrosin.

چکیده
A simple and sensitive spectrophotometric method for the determination of quinolone antibiotics was established based on an association complex formation with aluminum(III) and erythrosin. In the determination of ofloxacin as a quinolone antibiotic, Beer's law is obeyed in the range of 0.1 - 3.2 microg ml(-1), with an effective molar absorptivity at 555 nm and the relative standard deviation being 1.2 x 10(5) L mol(-1) cm(-1) and 0.9% (n = 6). This method was successfully applied to the assay of quinolone antibiotics in pharmaceutical preparations.

Ethyl Maltol as a New Ligand for Spectrophotometric Determination of Iron
In this study a new simple selective and sensitive spectrophotometric procedure for determination of Fe(III) is described. It is based on the formation of a colored complex between ferric iron and ethyl maltol, a strong and highly selective ligand for Fe(III). After mixing sample and reagent, and incubating at the room temperature, Fe(III)-ethyl maltol complex was extracted with different ...

H-Point Standard Addition Method (HPSAM) was applied for the simultaneous determination of V(V) and Fe(III). The method is based on the complex formation of V(V) and Fe(III) with chromazurol S (CAS) in acidic media and in the presence of cetyltrimethylammonium bromide (CTAB) as a micellizing agent. Acidic media and the presence of a micellar system improve selectivity and sensitivity. Fe (I...

Three rapid spectrophotometric methods were developed for the determination of sunitinib based on the formation of ion-pair complex in acidic medium with bromocresol purple, bromothymol blue, and bromophenol blue. The formed ion-pair complexes, extractable with chloroform, were measured at 422 nm for bromocresol purple, 425 nm for bromothymol blue and 427 nm for bromophenol blue. All these meth...
متن کامل[Simple screening method for judging the complex formation between drug and aluminum (III)].
We examined a simple screening method for judging the complex formation between a drug and aluminum(III) on a spot plate. As few drug had color reaction by basing on the binary complex formation of drug-aluminum(III), the ternary complex formation of drug-aluminum(III)-dye was studied this time using 50 kinds of drugs. The dyes used were Chromazurol S and Erythrosin. As a result, in the drug th...
