Batch and FIA Spectrophotometric Determination of Sodium and Potassium Ions via Reaction with Sulfophthalein Drivatized Crown Ethers
2004
Abstract
The mono- and bis- monoaza-15-crown-5-ethers and monoaza-18-crown-6-ethers, bound to the sulphophthalein dyes phenol and bromophenol red, were synthesized. Their complexing properties were studied
