| Summary: | 碩士 === 嘉南藥理大學 === 環境資源管理系 === 105 === The purpose of this study is to investigate the Electro-Fenton process feasibility in the removal of Acetaminophen (ACT) from the wastewater. Electro-Fenton process was employed in order to achieve the best ACT degradation and removal.
Acetaminophen,a non-prescription,analgesic,antipyretics,and anti-inflammatory drug(ex.Panadol),is defined by the Environmental Protection Administration as a new water contaminant or an "emerging contaminant" and is classified as one of the Pharmaceutical and Personal Care Products (PPCPs). As an emerging contaminant, ACT presents risks both in human health and ecosystem. ACT is also an Over-the-Counter (OTC) drug which indicates that its use is very convenient to any patient. Although this substance is very small and not very toxic, it does not mean that it will not have a negative impact on the environment and humans. Therefore, the objective of this study is to use Electro-Fenton process to remove ACT from simulated wastewater, and to facilitate practical applications. This study can be used as a reference by the future researchers.
ACT degradation was examined by varying ferrous ion (Fe2+) concentrations and hydrogen peroxide (H2O2) concentrations with fixed current supply at 1.5A and fixed pH=2.0. ACT removal rate reached 96% when Fe2+ concentration is at 1.0mM and H2O2 concentration is at 20mM, based on Fe2+ concentration test. On the other hand, based on H2O2 concentration test, a 100% removal rate was acheived when Fe2+ concentration is at 0.8mM and H2O2 concentration is at 25mM. In conclusion, both conditions can be used in order to achieve a good ACT removal efficiency.
