The first part of the study explored the adsorption of 4-chlorobiphenyl onto glass. When the initial concentration of 4-chlorobiphenyl was below 25 μg/L, the sample concentration became undetectable after 24 h. With respect to 4-chlorobiphenyl adsorbed onto glass, the adsorption rate constant k was 18 μg/h L, the adsorption equilibrium constant K was nearly 10-3 μg/L using the Langmuir first-order reaction model, and the monolayer saturated density, using the BET model, was 1200 μg/m2. In the second half of this study, the photocatalytic oxidation (UV/TiO2) of 4-chlorobiphenyl was investigated using its adsorption characteristics. The UV/TiO2 process decreased the 4-chlorobiphenyl concentration (initial concentration = 500 μg/L) by 77% within 120 min. The ratio between the TiO2 adsorption rate constant and the UV/TiO2 process degradation rate constant was 1/105.application/pdf222833 bytesapplication/pdfen-US4-chlorobiphenyl; Adsorption; Glass; Langmuir first-order reaction; Photocatalytic oxidation; UV/TiO2 process4 chlorobiphenyl; glass; polychlorinated biphenyl; titanium dioxide; unclassified drug; adsorption; aqueous solution; article; contamination; illumination; photoreactivity; priority journal; quality control; studyjournal article2-s2.0-0031573964http://ntur.lib.ntu.edu.tw/bitstream/246246/96796/1/15.pdf
