| 摘 要： | 应用模拟试验方法，在太阳光照射条件下，研究了被水中氰化物的化学动力学及光解结果。结果表明，废水中氰化物光解反应过程遵循一级反应动力学方程In(C0/C)=K1t；光解反应的半衰期为8．7－24.4h，可光解氰化物完全降解时间为3d；废水中易释放氰化物的光解去除率可达50．0％－83．7％，总氰化物的光解去除率为49．4％－56．9％。

| Abstract: | The photolysis kinetics and the photolysis results of cyanide in wastewater were studied under condition exposed to sunlight. The results showed that process of the photolysis reaction of cyanide followed the kinetics equation of first-order reaction ln(c0/c)=k1t. The half-life-period range of photolysis reaction are 8.7~ 24.4 hour. It would take three day for photolytic cyanide to be resolved completely. The photolysis removal rates of easy released cyanide in wastewater are 50.0% ~ 83.7%. The photolysis removal rates of total cyanide in wastewater are 49.4% ~ 56.9%. |
