Set up a kind of aqueous two-phase separation and enrichment of fluorine benzene
nicol, environment and food residue. Methods: acetone - ammonium sulfate as
extraction solvent, ultrasonic extraction and water two-phase separation phase
coupling, separation and enrichment of fluorine benzene nicol, can quickly.
Experiment discussed the acetone phase equilibrium and the influence of fluorine
benzene nicol, the factors affecting the separation and enrichment of: such as
salt, salt concentration, the kinds of system of pH, the addition of acetone
quantity, etc. Results: under the best conditions, 98.9% of the fluorine benzene
nicol, through step extraction into acetone rich phase, the method used in the
analysis of feed water, fluorine benzene nicol, residues in pork, fish, linear
range 0.09 1.5 mg/L, using the method of this kind of recovery of fluorine
benzene from water, pork, fish, take an examination of the efficiency of
98.4-105.7%, conclusion: the operation is simple, the pretreatment method and
the environmental pollution is small, so in the study of separation of
antibiotics has a certain application value.
