Evaluation of mesoporous imprinted silicas as MSPD selective sorbents of ketoprofen in powder milk

open access: yesMaterials Letters, 2017
Two molecularly imprinted mesoporous silicas were synthesized using different ratios of ketoprofen as template molecule and amino-functionalizaed 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 ...
