Photometric redox determination of iodate ions in bottled drinking water
TL;DR: In this paper, a photometric procedure is proposed for the highly selective determination of iodate ions in bottled natural drinking water treated with ozone. The procedure is based on the oxidation of Methylene Blue or Variamine Blue by iodate ion.

Uranium removal from nitrate solution by cation exchange resin (amberlite ir 120), adsorption and kinetic characteristics
TL;DR: In this article, the adsorption behavior of uranium ions from nitrate solutions using the strong acid cation exchange Amberlite IR120 resin has been investigated and the modelled data has been found to agree with both the exothermic pseudo first order reaction and the Langmuir isotherm.
