Abstract: By studying the adsorption and desorption ability of four different kinds of ion exchange resins named 201×7, AB-8, D301R and DAION PA312 to L-serine, the better resin named DAION PA312 was selected, and the best adsorption and desorption process parameters were also determined. Adsorption conditionsThe sample solution pH=9, the adsorption time was 20min, the actual exchange capacity was 94.25 mg/g; Desorption conditionsEluent was 0.2mol/L of phosphate buffer solution (pH=5), elution flow rate was 0.4 mL/min. The results showed that DAION PA312 had a high adsorption amount and lower adsorption time, which was suitable for the separation and purification of L-serine.
