Summary:•New mesoporous imprinted silicas were prepared using ketoprofen as template.•Materials were evaluated as sorbent in matrix solid phase dispersion for extraction of NSAIDs.•Results show that SBA-15-MIS-2 is appropriate to selective extraction of ketoprofen in powder milk. Two molecularly imprinted mesoporous silicas were synthesized using different ratios of ketoprofen as template molecule and amino-functionalized SBA-15 as support. The materials synthesized were characterized and evaluated as selective sorbents for matrix solid phase dispersion (MSPD) of ketoprofen in the presence of other nonsteroidal anti-inflammatory drugs (NSAIDs) in powder milk samples.
