Cobalt (II)-Mediated Molecularly Imprinted Polymer as a Monolithic Stationary Phase for Separation of Racemic Citronellal by Liquid Chromatography

Figure 2

UV spectra of (R)-(+)-citronellal after removed from the MMIP A column using the HPLC pump with the eluent mixture of methanol and acetic acid (9 : 1, v/v) at a flow rate of 0.05 mL min⁻¹. The measurement wavelength was 253 nm, and every step of washing was 1 h.
