| titleOfInvention | Method for determination of phosphorus in water |
| abstract | FIELD: determination of phosphorous in water. SUBSTANCE: method consists in formation of iron-containing phosphomolibdate in the presence of acetic acid with pH 2.0-4.0, its extraction with cyclohexanon and atomic absorption determination of phosphorus in extract by iron analytical line. Used as complexing agent is trivalent iron. Sodium molibdate is introduced to concentration indicated in invention description. Molar relation between trivalent iron and acetic acid amounts to (1-5):(1000-6200). EFFECT: higher efficiency. 2 tbl |
