تطوير طريقة طيفية مباشرة لتقدير الكلوربرومازين في المستحضرات الصيدلانية باستخدام مبادلات أيونية لإزالة المتداخلات

الملخص EN

In this scientific piece of research work, chlorpromazine CPZ (a psychaity drug) was determined spectrophotometrically using micro amount of reactant.

In addition to micro amount of spectrophotometric reagent (400 ^l).

Various oxidizing agents were tested, including periodate, iodate, bromate, ferric nitrate, ferri cynate and persulphate.

Oxidation reactions of the active ingradient (2,10-disubstituted phenothiazine) was used for the determination of CPZ in the presence of ferric nitrate.

Detailed study of all chemical and physical parameters were studied.

Ion-exchange columns were used to overcome the interfering ions.

Percentage linearity was 99.86 for 0.04-8 mM CPZ, L.O.D.

was 1x10"6M.

Repeatabilety was better than 1.5%.

The established results were followed to determine in some drugs.
