摘要
目的 考察三聚氰胺对游泳池水中氰尿酸的回收效果,确定最佳回收条件,为实际应用提供试验依据。方法 采用三聚氰胺回收法和液相色谱法及分光光度法,对游泳池水中氰尿酸的含量及回收率进行验证性检测,并分析影响因素。结果 三聚氰胺与氰尿酸最佳反应时间为20 min,最佳反应比例为1:1~1:1.2;强酸和强碱条件均不利于三聚氰胺与氰尿酸形成沉淀,最佳pH值为6~7。在研究条件下,游泳池水中氰尿酸回收率达84.70%。适当浓度的PO43--P能够提高氰尿酸回收效果;当PO43--P浓度为3 mg/L时,氰尿酸的最大回收率为98.54%。结论 应用三聚氰胺能够高效回收游泳池水中的氰尿酸,实现游泳池水资源化和无害化处理。
Objective To investigate recovery effect of cyanuric acid from swimming pool water using melamine,and to determine the optimal recovery conditions,so as to provide experimental evidence for practical application.Methods The recovery of cyanuric acid from swimming pool water was tested using the melamine recovery method,liquid chromatography,and spectrophotometry.The content and recovery rate of cyanuric acid were verified,and the influencing factors were analyzed.Results The optimal reaction time for melamine and cyanuric acid was 20 min,and the optimal reaction ratio was between 1:1 and 1:1.2.Strong acidic and alkaline conditions were not favorable for the formation of precipitates between melamine and cyanuric acid,with the optimal pH value ranging from 6 to 7.Under the study conditions,the recovery rate of cyanuric acid from swimming pool water reached 84.70%.An appropriate concentration of PO43--P could enhance the recovery effect of cyanuric acid.The maximum recovery rate reached 98.54%when the concentration of PO43--P was 3 mg/L.Conclusion The application of melamine can efficiently recover cyanuric acid from swimming pool water,which realized the resource utilization and harmless treatment of swimming pool water.
