Determination of organophosphoric and organophosphorothioic acids in aqueous solutions by ion chromatography

Geological and inorganic materials

“…Since the introduction of the technique in 1975 (34), the uses to which ion chromatography has been applied have multiplied rapidly. The technique originally described by Small et al (34) has been modified by eliminating the suppressor column (35-37), using coulometric detection for rare earth elements (38), or by using an UV detector in conjunction with the standard conductometric detector (39). Techniques for low conductivity eluents for anion chromatography are discussed by Gjerde, Fritz, and Schmuckler (40).…”

Determination of inorganic anions by ion chromatography with ultraviolet absorbance detection

“…Leuenberger et al determined nitrate and bromide in foodstuffs after separation on an amino-bonded silica column, using a UV detector at 210 nm (11). Bouyoucos and Armentrout combined a UV detector with the normal IC conductivity detector to monitor dialkylated organophosphorothionic acids which were obscured conductometrically by chloride (12). The author used the same combination of detectors to detect arómate and unsaturated sulfonic acids by IC (13).…”
