摘要: Acetonitrile can be salted-out from aqueous solution by adding tetrabutylammonium perchlorate. This phase separation method has been used for the extraction of Fe(III)-4,7-diphenylphenanthroline complex into acetonitrile followed direct injection onto an ODS column. The Fe is separated using 9:1 acetonitrile/water as a mobile phase. proposed reversed-phase high-performance liquid chromatography applied to determination in serum.
