Abstract—The presence of pounds in surface the United Kingdom [5,6]. China is the second largest ACTP
waters is an emerging environmental issue. This study manufacture country and many kinds of cold medicine used in
investigated the photodegradation of acetaminophen (ACTP) in China contain ACTP, and the major sources of
secondary effluent of a sewage treatment plant (STP) under environmentally-relevant emerging contaminants are primarily
simulated sunlight irradiation. ACTP can be quickly STP effluents. In this work, ic study of photodegradation
photodegradated in STP effluents, the degradation reaction was of ACTP in secondary effluent of a sewage treatment plant
fitted well into the first-order ic. Effects of pH values, ACTP under simulated sunlight irradiation using a medium-pressure
initial concentration and the addition of active species, such as mercury lamp (λ> 290 nm, 300W). The influences of addition
iron ions, nitrate ions, and humic acid (HA) were also discussed. Fe3+, NO - and HA to the effluents on the ACTP
Results showed that the photodegradation apparent rate constant
