Spectrophotometric and potentiometric determination of piroxicam and tenoxicam in pharmaceutical preparations.
Two simple and accurate methods are described for the determination of piroxicam and tenoxicam in their pharmaceutical preparations. The spectrophotometric method involves the oxidation of these drugs with potassium iodate in acid medium with the liberation of iodine and subsequent extraction with cyclohexane followed by measuring the absorbance at lambda=522 nm. Beer's law is obeyed in the con...
متن کاملIndirect flow-injection spectrophotometric determination of meloxicam, tenoxicam and piroxicam in pharmaceutical formulations.
A simple and sensitive indirect spectrophotometric method for the assay of meloxicam (MX), tenoxicam (TX) and piroxicam (PX) in pure and in pharmaceutical formulations by flow injection analysis (FIA) has been proposed. The method is based on the oxidation of these drugs by a known excess of N-bromosuccinimide (NBS) in an acidic medium, followed by a reaction of excess oxidant with chloranilic ...
متن کاملSpectrophotometric determination of uranium (VI) via complexation with piroxicam
An optimized and validated spectrophotometric method has been described for the quantitative analysis of uranyl ion in soil samples. The method is based on the chelation of uranyl ion with piroxicam to produce a yellow complex in 1,4-dioxan–water medium at room temperature which absorbs maximally at 390 nm. Beer’s law is obeyed in the concentration range of 6.75 × 10 – 9.45 × 10 μg mL with appa...
متن کاملSpectrophotometric Method for Hydrogen Peroxide Determination through Oxidation of Organic Dyes
Hydrogen peroxide is an important mild oxidant which is widely used in various applications including remediation of waste waters and drinking water resources. The safe level of H2O2 residue has to be controlled through accurate and precise measurement methods. A facile spectrophotometric method for the determination of hydrogen peroxide is based on the reaction of iodine ...
متن کاملcatalytic spectrophotometric determination of vanadium (iv) based on the oxidation of alkali blue by potassium bromate
a simple, rapid and sensitive spectrophotometric method has been proposed for the determinationof vanadium (iv). the method is based on the catalytic effect of v (iv) on the oxidation of alkali blue bypotassium bromate at ph 4. the rate of decrease in the absorbance of alkali blue (at 572 nm) wasproportional to the concentration of v (iv) in the range of 100-6000 ng ml-1. the detection limit wa...
