| Outline of Final Research Achievements |
This study consists of three parts for the better evaluation of drinking water treatment process: (1) ultra sensitive and selective method for residual chlorine; (2) kinetics of inactivation of viruses; (3) kinetics of in situ tracer compounds for the evaluation of flow pattern in ozone contactors for microbial risk assessment. Our new method with 3-chloro-4-hydroxy benzoic acid achieved a quantitation limit around 0.001 mg/L for free chlorine. Also, a flow tube system for the fast kinetics of ozone and viruses was established. Furthermore, as an in situ tracer in ozone contactor, the reaction rate constant of ozone and lidocaine was determined.
