| 摘 要： | 该文报道了关于硝酸盐作为地浸采铀氧化剂时NO_3~-的消耗、积累和降解产物的热力学分析及试验研究情况,指出NO_3~-的积累主要来源于NO_3~-型贫树脂吸附浸出液初期,而NO_3~-的降解产物主要是NO_2~-,从而为克服NO_3~-的积累和以氮化物为主要治理对象的地浸矿山环保工作的开展指明了方向。

| Abstract: | This paper reports the thermodynamic analysis and experimental results on NO3-' s consumption, accumulation and its degradation products when nitrate acts as oxidant in in situ leach of uranium. It is indicated that NO3 -'s accumulation originates principally from the initial stage when NO3- - resin absorbs uranium from extraction solution, and its main degradation product is NO2- . This has pointed the way for solving the problem of NO3-' s accumulation and for protecting the enviroment of mine in in situ leach of uranium whose main object is treating nitrogen compounds. |
