Following a simple dilution step, the drug was separated from interfering compounds on an octadecylsilica column protected by a precolumn. A mobile phase of aqueous tetrahydrofuran buf
Phenol and monochlorophenols were determined by reversed-phase liquid chromatography with LiChrospher RP-18e. A good separation was obtained with this system. The effectiveness of liquid-liquid and solid-phase extractions on Amberlite XAD-2, XAD-4, octadecyl Si 100, Tenax and Polyspher RP-18 were co
