Determination of Sulfates in Drinking Water

A novel approach for the design of a highly selective sulfate-ion-selective electrode

“…Commonly, sulfate is present in water in association with calcium, iron, magnesium and sodium ions as salts and hence, the determination of sulfate by sensitive, rapid, precise, and accurate methods is important in assessing the salinity and quality of water. 11,12 For a better ion-selective electrode, a strong interaction between the ionophore and the anion is essential in order to complex anions selectively, and the potential response is believed to be based on this characteristic of the membrane. Recent trends showed an increasing demand for developing novel ionophores.…”

Coulometric Titration of Hydroxyurea

“…Bromide ions are detected in the brominated solution using a simple argentometric spot test. The quantitative determination of Br 0 is performed by an argentometric titration with electrochemically generated Ag / at a current of 2 mA (8). A 500 ml aliquot of the HXU brominated solution, diluted 1000 times, is used for the titration.…”
