本文应用红外光谱与紫外光谱实验手段报导了508树脂吸附铀酰离子反应机理研究成果.研究成果初步得到以下三个结论: (1)由701预聚浆与5NAP生成508树脂的反应是生成醚键的化学反应,反应产物是R-O-R ??树脂母体,代号为701树脂). (2)紫外光谱方法证实,5NAP不吸铀.而508树脂却是一个优良铀吸附剂. (3)508树脂吸铀机理,是508树脂醚键与-NH_2基和UO_2~(2+)进行螯合. 以上结论,在国内外尚未见正式文献报导.
In this paper, we report the research results on the mechanism of uranyl ion adsorption on 508 resin by infrared spectroscopy and ultraviolet spectroscopy.The preliminary results of the research are as follows: (1) The reaction of 701 prepolymer and 5NAP to form 508 resin is to generate ether bond The reaction product is ROR ?? resin precursor, code-named 701 resin.) (2) UV spectroscopy confirmed that 5NAP does not suck uranium, while the 508 resin is an excellent uranium adsorbent (3) 508 resin uranium Mechanism is that 508 resin ether bond with -NH_2 group and UO_2 ~ (2+) chelation.The above conclusion, at home and abroad have not yet seen the formal literature.
