| 摘 要： | 一定浓度的亚硝酸盐溶液经太阳光模拟器照射一定时间后,观测溶液中亚硝酸盐的含量变化.改变溶液条件（介质、pH）和光照条件（时间、光强）等实验条件,同时进行黑暗对照实验,探求影响亚硝酸盐光解的因素和规律.结果表明,在光照的8 h内,时间越长亚硝酸盐的降解率越大,基本符合一级反应动力学曲线;光照强度越大亚硝酸盐的降解程度越大...

| Abstract: | The objective of this study was to investigate the photochemical reactions of nitrite in water.A nitrite solution was illuminated for a period of time under simulated sunlight,and the change of nitrite content in solution was observed.Different conditions of solution,such as concentration,temperature,medium and pH of medium,and conditions of illumination,such as duration,light intensity,and nitrite photodecomposition were discussed.Results showed that the longer illumination the higher the degradation rate ... |
