Experimental design for the optimization of the extraction conditions of polycyclic aromatic hydrocarbons in milk with a novel diethoxydiphenylsilane solid-phase microextraction fiber.


An innovative solid-phase microextraction coating based on the use of diethoxydiphenylsilane synthesized by sol-gel technology was used for the determination of polycyclic aromatic hydrocarbons at trace levels in milk. The effects of time and temperature of extraction and acetone addition were investigated by experimental design. Regression models and… (More)
