利用气体火花放电产生离子,以低能氮离子注入两种羧酸的水溶液中,利用高效液相色谱(HPLC)对离子注入后的样品进行分析.结果表明,氮离子注入可使氮沉积在溶液中,生成氨基酸及其它氨基化产物,这一结果不仅验证了低能离子注入样品时的“质量沉积”效应,而且还是原始地球条件下氨基酸生成的一种可能的途径.

s Low energy ions were produced by N2 glow discharge, the positive ones were accelerated into acetic acid solution and propanoic acid solution respectively to induce chemical reactions. Samples were analyzed by a Waters 600 HPLC analyzer. It showed that N was deposited into the solution, ammonia and amino acids were produced by such kind of implantation , for acetic acid solution, glycine (Gly) was found, for propanoic aicd solution, they were glycine (Gly), serine (Ser) and alanine (Ala). Mechanism of the production of ammonia and amino acids were discussed. As amino acids were synthesized in solution under oxidative atmosphere, this method overcame the defaults of the old ones which needed reducing conditions or a gaseous atmosphere. It was generally thought that life was born in oceans and there were a large amount of low energy particles near the surface of the original earth generated from thunder, lightening, volcano and emission of radioactive elements in the crust which might have played an important role in the chemical origin and evolution of life. The results we gained not only confirmed the “ mass deposition effect” of low energy ion implantation, but also presented a possible way for the transferring of N from air to oceans and the production of ammonia and amino acids under primitive earth conditions.
