development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
UV spectrophotometry and nonaqueous determination of terbinafine hydrochloride in dosage forms.
An ultraviolet spectrophotometric and a nonaqueous volumetric method for determining terbinafine hydrochloride (TH) in pharmaceutical formulations are presented. The UV spectrophotometric procedure was developed for assay of TH in raw materials, tablets, and creams. The method was tested for linearity (0.8-2.8 micrograms/mL, r = 0.9997), recovery (102.00% for creams and 99.90% for tablets) and ...
متن کاملSpectrophotometric and Spectrofluorimetric Methods for the Determination of Dothiepin Hydrochloride in its Pure and Dosage Forms using Eosin
Spectrophotometric and spectrofluorimetric methods were developed for the determination of dothiepin hydrochloride (DOP) in different dosage forms. The spectrophotometric method (Method I) is based on formation of a binary complex with eosin at 540 nm in acetate buffer of pH3.7. The absorbance-concentration plot is rectilinear over the range 1-10 μg/mL with LOD of 0.18 μg/mL and LOQ of 0.54 μg/...
متن کاملFluorimetric Methods for the Determination of Terazosin HCl in Drug Substance and Dosage Forms
Determination of terazosin hydrochloride dihydrate (TRZ) in drug substance and tablets was studied by fluorimetric techniques. The fluorimetric methods are based on: (1) measurement of the native fluorescence of the drug in water at 750 nm after excitation at 330 nm. (2) sensitizing the native fluorescence by formation a binary complex of drug with aqueous uranyl acetate (0.1% w/v) at the same ...
متن کاملSimultaneous Determination of Montelukast Sodium and Bambuterol Hydrochloride in Tablet Dosage Form by Ultraviolet Spectrophotometry
A simple, accurate, and precise dual wavelength spectrophotometric method was developed for simultaneous determination of Montelukast Sodium (MTKT) and Bambuterol Hydrochloride (BAM) in combined pharmaceutical dosage forms. The method based on determination of MTKT at 322.0 nm using its absorptivity value and BAM at 266.0 nm after deduction of absorbance due to MTKT. The two drugs follow Beer-L...
