对氨基苯磺酸钠在循环水加药系统中的应用研究
|
摘要
通过对循环水系统的条件进行模拟,对对氨基苯磺酸钠(C_6H_6NO_3SNa)的荧光特性进行了评价。结果表明:循环水的温度、pH、盐离子和有机磷对C_6H_6NO_3SNa的荧光强度几乎没有影响,只有杀生剂会对荧光强度产生削弱作用,在工业中可以通过增大投加量的方法来解决。在实际循环水中,以C_6H_6NO_3SNa作示踪剂,复配水处理剂C_6H_6NO_3SNa-PAA的最低检出限为2.68×10~(-4)mg/L。该实验证实了C_6H_6NO_3SNa可以被用作循环水中的荧光示踪剂,在工业上对水处理剂的在线检测中具有较强的应用价值。
The fluorescence characteristics of C_6H_6NO_3SNa have been evaluated by simulating the conditions of circulating water system. The results show that temperature,pH,salt ions and organophosphorus almost have no influence on the fluorescence intensity of C_6H_6NO_3SNa. Only can biocides have weakening effect on the fluorescence intensity. This problem can be solved by increasing the dosage of C_6H_6NO_3SNa. In actual circulating water,C_6H_6NO_3SNa is used as tracer,the lowest detection limit of composite water treatment agent C_6H_6NO_3SNa-PAA is 2.68×10~(-4)mg/L.This experiment proves that C_6H_6NO_3SNa can be used as fluorescence tracer in circulating water,having strong application value industrially for on-line detection technique of water treatment agent.
