Abstract

Adsorption of water-soluble vitamins, including riboflavin (В2), nicotinamide (PP, B3), pyridoxine (B6), cyanocobalamine (В12) from water-organic solutions on microdispersed sintered detonation nanodiamond (MSDN), modified in different ways, was studied using high-performance liquid chromatography (HPLC). The effect of composition (from 5% to 80 v/v % of CH3CN) and рН (рН 2.7/6.0) of mobile phase, as well as temperature of chromatographic column (tc = 45/65 °C) on vitamins adsorption was studied. Nonlinear dependences of the sorbate retention factors on the acetonitrile content in the mobile phase are found out, indicating the variation of specific and non-specific interactions of vitamins with MSDN surface. Based on the obtained results, the conditions for chromatographic separation of the mixture of water-soluble vitamins in isocratic mode of HPLC on MSDN are optimized.
