摘要：

A method for the rapid extraction and analysis of milk or infant formula for bis(2-ethylhexyl) phthalate (DEHP) by high-performance liquid chromatography (HPLC) is reported. The method eliminates separatory funnel extraction and does not require a residue cleanup by gel permeation chromatography (GPC). Samples are solvent-extracted after being mixed with 10% deactivated silica. The extract is concentrated by Kuderna-Danish evaporation and the resulting residue analyzed directly by HPLC with UV detection. A method detection limit of 100 ppb was calculated. The overall time required for a complete determination is improved over methods using separatory funnel extraction and GC analysis by approximately 3-fold. Spike recovery of DEHP from infant formula and four different milk types (raw, whole, low-fat, and skim milk) ranged from 65% to 80% recovery at the 10 mg/L spike level. © 1990, American Chemical Society.
