METHOD FOR QUANTITATIVE DETERMINATION OF MIX OF ORTHO-, PYRO-, TRIPOLI- AND META-PHOSPHATES

摘要

Method for quantitative determination of ortho-, and metaphosphates includes preparation of column, dissolution of sample and its introduction into column. Sample is passed through column of eluent. Phosphates are collected in separate portions of eluate and evaporated. Quantitatively one determines phosphates. As ion exchange tar one uses anionite. As eluents one uses solutions of CHl.
