Sodium-Selective Fluoroionophore-Based Optodes for Seawater Salinity Measurement.
Müller BJ, Rappitsch T, Staudinger C, Rüschitz C, Borisov SM, Klimant I. Müller BJ, et al. Anal Chem. 2017 Jul 5;89(13):7195-7202. doi: 10.1021/acs.analchem.7b01373. Epub 2017 Jun 16. Anal Chem. 2017. PMID: 28585806
Among different polyurethane hydrogels investigated, the hydrogel D1 featuring the highest water uptake was found to be the most suitable due to the highest dynamics between "off" and "on" states. Due to little or no cross sensitivity to other ions (e.g., Mg(2+), Ca(2+), K …
