determination of potassium sodium and total alkalies in

a simple flow injection with flame photometric detection has been developed for determination of sodium potassium and total alkalies in portland cement fly ash admixtures and water of concrete. a liquid sample or a digest of solid sample was injected into a water carrier stream which flowed to a flame photometer.

practical 2: determination of sodium and potassium ion

practical 2: determination of sodium and potassium ion concentrations 2.1 introduction the aims of this practical are: • to demonstrate safe laboratory working procedures • to demonstrate two simple but different techniques for making the clinically important measurements of sodium and potassium ion concentration

spectrophotometric determination of sodium by ion-pair

possible interferences by multivalent cations are masked by edta- a selective photometric determination of potassium with ls-crown-6 and bromocresol green has already been described [1] ; the potassium complex of the crown ether was extracted into benzene as an ion-pair with the dye anion.

determination of the concentration of potassium ion using

background. the aim of the experiment is to determine concentration of potassium ion using flame photometry (atomic emission spectrometry). flame photometry is also known as atomic emission spectrometry. when a solution containing cations of sodium and potassium is spayed into flame the solvent evaporates and ions are converted into their atomic state.
