The invention discloses a method for separating and purifying a creatine mother liquor. The method is as below: sending a mother liquor after creatine synthesis by using a pump through a feeding tube to an electrodialyser for separation. The mother liquor contains 0.01-5% of creatine and 0.1-25% of an inorganic salt; the electrodialyser is equipped with an electrodialysis membrane; and the electrodialysis membrane has different permeability on creatine and inorganic salt. The method for separating and purifying a creatine mother liquor is simple, economical and safe, and achieves clean production. 本发明公开了种肌酸母液的分离净化方法，将合成肌酸后的母液利用泵通过送液管送至电渗析器中进行分离；所述母液中含有0.01~5%的肌酸和0.1~25%的无机盐；所述电渗析器中装有电渗析膜，所述电渗析膜对肌酸和无机盐透过性不同。本发明是种简便易行、经济、既安全又能实现清洁化生产的肌酸母液的分离净化方法。
