Trends in the behavior of dissolved organic substances under the conditions of freeze extraction

Influence of the extractant and pH on the efficiency of the preconcentration of organic compounds dissolved in water is studied in freeze extraction. The revealed trends are discussed in terms of the proposed theoretical model; some new experimental proofs to it are presented. The advantages of the...

Description
Summary:Influence of the extractant and pH on the efficiency of the preconcentration of organic compounds dissolved in water is studied in freeze extraction. The revealed trends are discussed in terms of the proposed theoretical model; some new experimental proofs to it are presented. The advantages of the method proposed over liquid extraction (concentration factor) and directed low-temperature crystallization (selectivity) are demonstrated.
