Spectrophotometric determination of gallium(III) with rutin.

Development and Determination of Rutin by Spectrofluorimetric Method

Rutin is a polyphenolic naturally occurring compound potentially having a huge impact in human benefit which includes wound healing, cardiovascular, carcinoma therapeutic activities as well as have nutraceutical benefits. The objective of study was to establish a precise, accurate, sensitive and reliable method for estimation at low concentrations of rutin in biological fluids, using spectroflu...

Synthesis of graphene oxide-TiO2 nanocomposite as an adsorbent for the enrichment and determination of rutin

Objective(s):  In our study, graphene oxide-TiO2 nanocomposite (GO/TiO2) was prepared and used for the enrichment of rutin from real samples for the first time.  Materials and Methods:   The synthesized GO/TiO2 was characterized by X-ray diffraction, scanning electron microscopy, and FT-IR spectra.  The enrichment process is fast and highly efficient. The factors including contact time, pH, and...

Kinetic Spectrophotometric Method for Determination of S032- Using Methylen blue

The present work reports a kinetic spectrophotometric method for the determination of traceamounts of sulphite that is based on inhibitory effect of sulphite on the oxidation of Methyleneblue (MB) in acidic media. The reaction is followed spectrophotometrically by monitoring thedecrease in absorbance of MB at 664 nm with a fixed time of 0.5-4.5 minutes. It was found thatsulphite exert a strong ...

KINETIC DETERMINATION OF ASCORBIC ACID a WITH SPECTROPHOTOMETRIC DETECTION

A simple and rapid method has been developed for the determination of ascorbic acid in fruit and pharmaceutical products. The method is based on the measurement of the reaction rate between ammonium molybdate and ascorbic acid in acidic media. The reaction was monitored spectrophotometrically at 800 nm by fixed-time and variable-time methods. The calibration graph was linear in the range of...
