Uranyl tris nitrato i.e. [UO (NO ) ] was formed by adding tetramethylammonium nitrate to uranyl nitrate in acetonitrile medium. The luminescence features of this complex in acetonitrile are very sensitive to water content, which could lead to the use of it as a luminescent probe for water present in acetonitrile. The luminescence intensity ratio of 507 to 467 nm peak of uranyl tris nitrato showed a linear response in the range 0-5% (v/v) water content in acetonitrile. The present method was applied for three synthetic samples of acetonitrile for water detection and the results obtained were compared using Karl Fischer titration. There was a good agreement in the values obtained by both the methods.
三硝酸铀酰，即[UO(NO₃)₃]，是通过在乙腈介质中将硝酸四甲基铵添加到硝酸铀酰中形成的。该配合物在乙腈中的发光特性对水含量非常敏感，这使得它有可能用作检测乙腈中水分的发光探针。三硝酸铀酰507至467纳米峰的发光强度比在乙腈中水含量为0 - 5%（v/v）的范围内呈线性响应。该方法用于三个乙腈合成样品的水分检测，并将所得结果与卡尔费休滴定法进行比较。两种方法获得的值吻合良好。
