Spectrophotometric determination of cerium(IV) using a phenothiazine derivative.
A simple, rapid and sensitive spectrophotometric method has been proposed for the determination of cerium(IV) using a phenothiazine derivative, propionyl promazine phosphate (PPP). This method is based on the formation of a red-colored radical cation upon a reaction of PPP with cerium(IV) in a phosphoric acid medium having maximum absorbance at 513 nm. Beer's law is valid over the concentration...
متن کاملSpectrophotometric determination of vanadium(V) in minerals, steels, soil and biological samples using phenothiazine derivatives.
Two simple, rapid and sensitive spectrophotometric methods have been proposed for the determination of vanadium(V) using butaperazine dimaleate (BPD) and propionyl promazine phosphate (PPP). These methods are based on the formation of red-colored radical cations on reaction with vanadium(V) in phosphoric acid medium, with their absorbance maxima at 513 nm. Beer's law is valid over the concentra...
متن کاملSimple determination of high urinary excretion of 5-hydroxyindole-3-acetic acid with ferric chloride.
We describe a method for determination of urinary 5-hydroxyindole-3-acetic acid, a metabolite of serotonin and tryptophan and a useful indicator of metastasizing carcinoid tumor. The analysis is based on the color development with ferric chloride added to the residue obtained on evaporating a diethyl ether extract of the sample that has been acidified with sulfuric acid and saturated with sodiu...
متن کاملNitrate removal from water using alum and ferric chloride: A comparative study of alum and ferric chloride efficiency
Background: Nitrate is an acute and well-known hazardous contaminant, and its contamination of water sources has been a growing concern worldwide in recent years. This study evaluated the feasibility of nitrate removal from water using the traditional coagulants alum and ferric chloride with lower concentrations than those used in the conventional coagulation process. Methods: In this research...
متن کاملFerric Chloride in Wastewater Treatment
Wastewater Treatment Facilities have been built to remove biological and chemical waste from water as it is used. These facilities maintain a healthy environment for organisms as well as people because it removes potentially harmful material and kills pathogens that would easily spread through cities. Phosphorus is a compound of interest because a high concentration of it at discharge will even...
