AB  - A zeolitic imidazolate framework (ZIF)-8-silica hybrid monolithic column was 
      prepared by one-step sol-gel method. The stationary phase in the monolithic 
      column was characterized by Fourier-transform infrared spectra, X-ray 
      diffraction, thermogravimetric analysis, nitrogen adsorption/desorption, and zeta 
      potential. The results showed that ZIF-8-silica hybrid monolithic materials had 
      abundant functional groups, good crystallinity, large specific surface area, and 
      good thermal stability. A capillary electrochromatography (CEC) chiral separation 
      system was for the first time constructed with ZIF-8-silica hybrid monolithic 
      column and sulfobutylether-beta-cyclodextrin (SBE-beta-CD) as a chiral additive and was 
      applied to separate the selected single and mixed chiral compounds (13 natural 
      amino acids and 5 chiral pesticides). Under the optimized CEC conditions, all the 
      single analytes achieved baseline separation with resolution of 2.14-5.94 and 
      selectivity factor of 1.06-1.49 in less than 6 min, and the mixed amino acids 
      with similar properties were also simultaneously enantioseparated (Rs >/= 1.82). 
      Relative standard deviations (RSDs) of migration time and column efficiency were 
      lower than 4.26% and did not change significantly after 200 runs, evidencing 
      excellent reproducibility and stability. These results demonstrate that the 
      application of SBE-beta-CD as a chiral additive for ZIF-8-silica hybrid monolithic 
      columns is a promising method for the separation of chiral compounds.
