| 摘 要： | 氰化物在海水中质量浓度过高时,会对水生生物产生极大的危害.氰化物在海水中通过降解会产生自净效应,且降解效果受多种条件的影响.以氰化物在近海海水中降解过程为研究对象,总结了温度、pH值、光照条件、搅拌强度、溶解氧含量等因素对氛化物降解效果的影响,并研究了氰化物在海水不同条件下的反应动力学,经验证符合一级动力学反应.该实验...

| Abstract: | In the condition of high concentration,cyanide can endanger the sea creatures.Cyanide concentration can decrease itself by photochemical degradation in the seawater,while the decomposition rate is different in various conditions.With the degradation process of CN-in near coastal water as research object,this paper summarizes the influences of temperature,pH,stir intensity,light conditions,dissolved oxygen content on CN-degradation,and analyses the reaction dynamics.It is confirmed that the cyanide photochem... |
