... The +ve end of H2O dipole is oriented toward the Clions, and the –ve end of the H2O dipole is oriented toward the Na+ ions. The ion-dipole attractions between the ions and H2O molecules are strong enough to pull the ions from their positions in the crystal. Once separated from the crystal, the Na+ a ...

... range of 280−370 nm [14]. The change in this optimum pH leads to the decrease in the concentration of Fe[OH]2+ complexes and it can also result in the precipitation of ferrous ion as oxy-hydroxides. The various photoactive species of iron, formed under different pH conditions, are Fe[H2O]63+ (pH 1−2 ...
