Magnesium isotope effects by ion exchange using monoazacrown (1-aza-18-crown-6) bonded Merrifield peptide resin were investigated. The capacity and distribution coefficient were determined. The separation factors, (24Mg2+/25Mg2+)Resin/(24Mg2+/25Mg2+)Solution, (24Mg2+/26Mg2+)Resin/(24Mg2+/26Mg2+)Solution, and (25Mg2+/26Mg2+)Resin/(25Mg2+/25Mg2+)Solution were 1.0071, 1.0132, and 1.0068, respectively. The heavier magnesium isotopes were enriched in the solution phase, while the lighter isotopes were enriched in the resin phase. It was found that the hydration and isotope mass effects are more significant than that of the complexation
