摘要:

用25keV氮离子束辐照苯甲酸钠(PhCOONa)引起其分子结构的变化,通过紫外分光光度计的分析,得到了其残余紫外活性的剂量效应曲线,另外通过高分辨富里叶红外光谱仪及高灵敏度的茚三酮反应的测定,发现了辐照后的样品中有腈基及α-氨基酸等产物.

Abstract:

The effect of 25 keV N+ ion beam radiation on the change of molecular structure of PhCOONa was studied. The dose curve was obtained from the analysis of the ultraviolet spectra. Based on the results of highly resolved FTIR spectra and high-sensitive ninhydrin reaction it was proved that in the implanted PhCOONa sample benzonitrile and α-amino acid could be produced by the N+ ion beam.

Key words: N+ ion implantation, PhCOONa, Mass deposit effect
