综述了萃取分离氨基酸的各种方法的研究进展。在此基础上，提出了氨基酸核电中性分子的萃取分离途径，并实验证明通过质子转移反应分离氨基酸荷电中性分子的可能性。 The research progress of various methods of extracting and separating amino acids is reviewed. On the basis of this, a new method of extraction and separation of neutral molecules in amino acid nuclear power was proposed, and the possibility of separating neutral amino acid charged neutral molecules by proton transfer reaction was experimentally proved.
