An indirect, sensitive and accurate method for the determination of trace amounts of hydrazine is described. In this proposed the spectrophotometric method is based on its reduction properties of hydrazine with a known concentration of potassium permanganate to reduce the colour. The absorbance of unreduced permanganate is measured the colour difference at different wavelengths 546 and 526 nm w...

Two simple, rapid and sensitive spectrophotometric methods developed for Chlorpheniramine Maleate (CPM) and Diphenhydramine Hydrochloride (DPH) determination in pure and pharmaceutical preparation using Potassium Permanganate. The solvent system used was potassium permanganate. The method developed by adding a known amount of permanganate to CPM and DPH in acid and alkaline medium, the unreacte...

in this research, kiwifruits (hayward) were selected in two mass ranges (large and small). they were placed in one-liter glass bottles in the vicinity of the polyethylene sachets containing potassium permanganate nano-zeolite (0, 0.2, 0.4 and 0.8 g) and were stored in a germinator (5°c temperature and 30% relative humidity). then, the physicochemical properties of the fruits (soluble solid cont...

A simple, sensitive and rapid flow-injection chemiluminescence method has been developed for the determination of ferulic acid based on the chemiluminescence reaction of ferulic acid with potassium permanganate in a nitric acid medium. A strong chemiluminescence signal was observed when ferulic acid was injected into an acidic potassium permanganate solution in a flow-cell. The present method a...

a pvc ion-selective membrane electrode based on cd-tetraphenyl porphyrine as a carrier was prepared fordetermination of mno4- ion. this electrode revealed good selectivity toward permanganate ion over a widevariety of anions. effects of some experimental parameters such as nature of the plasticizer, the amounts ofcarrier and additive, and concentration of the internal solution on the potential ...

THE CLASSICAL PROCEDURE for the determination of calcium in biologic fluids involves the precipitation of calcium as the oxalate and titration of the oxalate with potassium permanganate. The permanganate titration has certain difficulties. The oxalate solution has to be heated during the titration (1) and the end point is unreliable in dilute solutions (2). The use of cerate oxidimetry avoids t...

In our studies on perosis in chicks, it was found desirable to be able to determine small amounts of manganese of the order of 0.1 to 10 micrograms. Such a method was necessary for the determination of manganese in bones, blood, and similar materials. The formaldoxime method of Sideris (1) was found unsuitable, as the determination is carried out in alkaline solution. Under these conditions pho...

The oxidation – reduction reaction of trinitrotoluene (TNT) with potassium permanganate solution and the colorless rate of it are used as a quality control test in industry to verify the purity of TNT. The impurities such other derivatives of TNT are due to increasing of colorless rate of potassium permanganate solution. On the other, nitrotoluene sulfonates are usually formed in the step of ad...
