Spectrophotometric determination of potassium in river water based on solvent extraction of the complex formed with a crown ether and an anionic azo dye using flow injection

A study was conducted to optimize a flow injection, solvent extraction, spectrophotometric procedure for the determination of potassium in freshwaters. Three analogues of 18-crown-6 were examined as the crown ether, 4 analogues of the anionic azo dye, 4-(4-dialkylaminophenyl)azo-2,5-dichlorobenzene...
