Zaporozhets, L. Zin'ko, I. Kachan] Solid-phase-spectrophotometric and test procedures are proposed to determine phosphorus as its ion associate with a quaternary ammonium salt and molybdoantimonophosphoric acid immobilized on silica gel in the concentration range 1.9-124 μg P/L. The determination of 4 μmol of phosphorus is not affected by (in μmol) alkali and alkaline-earth metals (≤2 × 104), NH 4 + (≤1 × 103), Co2+ (≤1.0), Cu2+ (≤100), Mn2+ (≤10), Fe3+ (≤300), NO 3 − and SO 4 2− (≤2 × 104), CO 3 2− (≤1 × 104), As (≤20), and Si (≤1 × 103). The procedure was tested in the determination of various phosphorus forms in natural waters. Pleiades Publishing, Ltd., 2007 Zaporozhets O. Shevchenko National University, Kiev, ul.
