摘要
文章提供的红外光谱分析法 ,对复合缓释肥中N ,P的分析 ,可在不经分离的情况下 ,通过红外图谱同时得出N ,P的释放量。分析时不需任何试剂 ,取一次样几分钟内可得出结果。
Infra red spectroscopy described in this paper proved to be a rapid and simple method as compared with the conventional chemical analysis of N and P release in compound slowly releasing fertilizer. No re agent and no separation was needed in this procedure, the release of N and P was shown directly on the infra red spectrogram and it took only a rew minutes to analyse a sample.
