Synthesis of hierarchical porous zirconium dioxide and its application in the detection of sulfonamides in animal-derived food.

In order to effectively remove grease for the detection of sulfonamides, a non-toxic and low-cost hierarchical porous zirconia material was synthesized using the dual template method. The lipid impurities in an animal-derived food matrix can be absorbed by hierarchical zirconia. A ZrO prepolymer was synthesized by mixing amphiphilic triblock copolymer poly(ethylene glycol)--poly(propylene glycol)--poly(ethylene glycol) (P123) with tannin extract as the double template and Zr(SO) as the metal source.
