Spectrophotometric Determination of Nickel with Chlorophosphonazo-III
The optimum conditions for spectrophotometric method for the determination of Ni with chlorophosphonazo-III (CPA-III) were established and the nickel content in water samples has been successfully determined. In a pH 5.5 acetic acid-sodium acetate buffer medium, CPA-III and Ni formed a 1:3 green blue complex and the maximum absorption wavelength of the complex is at 620 nm. Ni content in a rang...
متن کاملSpectrophotometric determination of the stability constant of vanadium(v)-p-chloro-N-phenyl-p-chlorobenzo- hydroxamic acid complex
The stability constant of the complex vanadium(v) p-chloro-N-Phenyl-p-chlorobenzohydroxamic acid was determined spectrophotometrically. The ligand p-chloro-N-phenyl-p-chloro-benzohydroxamic acid abbreviated in this paper as PCNPPCBHA was synthesized by the coupling of equimolar solutions of p-chlorobenzoyl chloride and freshly prepared p-chloro-ß-phenyl hydroxylamine; in which the later was pre...
متن کاملSpectrophotometric determination of Cilastazol using p-dimethylaminobenzaldehyde
A simple accurate and reproducible spectrophotometric method was established for the estimation of Cilastazol based on the formation of condensation product. The method is based on the formation of yellow colored chromogen, when the drug reacts with p-Dimethylaminobenzaldehyde (PDAB). The colored species has an absorption maximum at 425 nm and obeys Beer's law in the concentration range of 6-10...
متن کاملSpectrophotometric Determination of Hydralazine Using p-Dimethylaminobenzaldehyde
A new spectrophotometric method for the assay of hydralazine hydrochloride in bulk and dosage forms has been developed. The procedure is based on a condensation reaction between alcoholic solution of hydralazine and acidic solution of pdimethylaminobenzaldehyde to generate an instant greenish-yellow coloured product. The hydrazone formed absorbed visible light strongly and optimal detector resp...
متن کاملSequential separation and spectrophotometric determination of osmium and platinum with 5-chloro-2-hydroxythiobenzhydrazide.
Osmium was determined spectrophotometrically after coprecipitation with 5-chloro-2-hydroxythiobenzhydrazide at room temperature in the pH range 2.5-5.0 and collection on microcrystalline naphthalene. Beer's law was obeyed in the concentration range 1.8-14.4 ppm of osmium in a chloroform solution at 510 nm. The molar absorptivity and Sandell sensitivity were 1.056 x 10(4) l mol(-1) cm(-1) and 0....
