摘要
本文根据硝酸磷肥的特性和同位素示踪的要求,经过实验,提出了在实验室条件下合成(5)~N(32)~P 双标记硝酸磷肥的途径。工艺流程可靠,回收率高,可根据需要设计标记比强和丰度。有使用价值。
According to the isotope labelling technique requirements and our expe- rimental result,a more rational method used to tag double labelled nitropho- sphate fertiliger with ^(15)N and ^(32)P was recomended.Several concrete technologi- cal processes were also discussed in this paper.Recomended method is rational in producing route and it can be used to synthetize labelled nitrophosphate fertilizer with demonded specific activity of ^(32)p and demonded abundance [of ^(15)N.
