Title: Molecularly Imprinted Dispersive-Based Extraction Method for Melamine in Milk (MIDE HPLC DAD)
Issue Date: 2014
Abstract: An easy and selective molecularly imprinted dispersive extraction method (MIDE) coupled with HPLC-DAD was developedfor melamineŽs analysis in commercial milk samples. The molecularly imprinted polymer (MIP) was synthetized bysuspension polymerisation with melamine as template, while methacrylic acid, ethylene glycol dimethacrylate andchloroform were used as monomer, cross-linker and porogenic solvent, respectively. The analytical methodology wasvalidated presenting a limit of detection of 0.6 mg/kg. The recovery percentage in spiked milk samples ranged from 92.9%to 102.0% with an intermediate precision of 5.0%. The analysis of real samples with MIDE revealed melamineŽs presencein 20% of the cases with a maximum concentration of 9.3 ± 0.3 mg/kg, which exceeds the maximum recommended levelof 2.5 mg/kg.
