A sensitive, simple and selective spectrofluorimetric method
has been proposed for determination Captopril (CPT) in pure form
and pharmaceutical preparations. This method depends on the
formation of complex between Captopril and Copper (II) at
pH=3.5.
A new, simple and sensitive kinetic spectrophotometric
method has been proposed for the determination of tropicamed
(TPC) in pure and pharmaceutical formulations. The method is
based on oxidation TPC by potassium permanganate in strong
alkaline m
edium (pH=12) to form green colored product with
absorbance maximum at 610nm.
