Spectrophotometric Determination of Trace Amounts of Mercury With Phenanthroline and Eosin
Owing to the toxicity of mercury in the environment, the determination of trace amounts of mercury has attracted great attention. I 32 The conventional technique of dithizone extraction is not always favoured because the procedure is cumbersome, sensitive to light and is subject to interferences from other metal ions.3 Analytical methods based on ternary complex formation seem to offer superior...
متن کاملSpectrophotometric determination of Fe (II) using ternary complex with SCR and 1,10-phenanthroline
Fe (II) forms a coloured ternary complex with SCR in presence of 1,10-Phen which have molar absorptivity of 3.56x104 mole-1 cm-1 at pH 5.0 and λmax 520 nm. The complex contains three molecules of 1,10-Phen coordinated to Fe (II) ion and one molecule of SCR through ion association giving the overall formula Fe (II) (SCR) (Phen)3. Beer’s law range is 0.0223-1.6084 ppm and Sandell’s sensitivity 0....
متن کاملSpectrophotometric Determination of Iron(II) with 5-Nitro-6-amino-1,10-phenanthroline
Gravimetric, titrimetric, polarographic, optical and radiochemical methods have been reported for the determination of iron(II) and (III). Numerous reagents have also been reported for the spectrophotometric determination of Fe(II); for example, thiocyanate, dipyridine, tripyridine and 1,10-phenanthroline. The 1,10phenanthroline family has been extended to the use of dihydroxy, dimethyl, nitro ...
متن کاملSpectrophotometric and derivative spectrophotometric determination of aluminium with Hydroxynaphthol Blue.
The reaction of aluminium(III) with Hydroxynaphtol Blue (HNB) in aqueous media at apparent pH 5.5 results in a red complex that is stable for at least 4 hr. Beer's Law is obeyed up to 1.6 microg/ml of aluminium(III) with an apparent molar absorptivity of 1.66 x 10(4) l.mol(-1). cm(-1) at 569 nm. This paper proposes procedures for aluminium(III) determination by ordinary and first-derivative spe...
متن کاملIndirect spectrophotometric determination of some biologically important phenothiazines using potassium dichromate, iron(II) and 1,10-phenanthroline
A sensitive method is presented for the spectrophotometric determination of phenothiazine derivatives of biological importance. The drugs namely, chlorpromazine hydrochloride (CPH), promethazine hydrochloride (PH), trifluoperazine hydrochloride (TFPH), prochlorperazine maleate (PCPM) and fluphenazine hydrochloride (FPH) are reacted with a fixed amount of dichromate in acidic conditions. After t...
