I. A search for organic compounds as colorimetric quantitative reagents for inorganic ions ; II. A study of the reaction between 2 acetamino 6 amino benzo thiazole and chloroiridic acid
The reaction between 2 acetamino 6 amino benzo thiazole and chloroiridio acid is not sensitive enough to be of importance as a colorimetric quantitative reaction. IrCl₆-- can be detected with this organic compound if iridium is present in as much as 0.02 mg. per ml. of solution providing ferric …

Optimizing a hybrid reverse osmosis/electrodialysis system for natural organic matter concentration
… concentrate NOM. However, it also concentrates inorganic ions which lead to an increase in the osmotic pressure, eventually rendering RO ineffective, and potentially producing membrane scaling. Salts are also harmful to mammalian cells at high concentrations, which may cause artifacts in the …

Effect of adsorption of non-protolyzable anions on goethite (alpha-FeOOH) mobility
… ARE IMPORTANT CONTROLS ON THE MOBILITY OF MANY INORGANIC IONS IN THE ENVIRONMENT. ANION ADSORPTION ON IRON HYDROXIDE USUALLY DECREASES THE PARTICLE MOBILITY AND MAKES THE PARTICLE SURFACE LESS POSITIVE. HOWEVER, FOR SOME NON-PROTOLYZABLE ANIONS LIKE FLUORIDE AND ARSENITE, THE ADSORPTION HAS …
