| Abstract | Kinetics of 4-chlorophenol (4-CP) dechlorination by Pd/Fe@SiO2 composite nanoparticles synthesized under ultrasound irradiation was explored. The diameters and specific surface areas of most Pd/Fe@SiO2 composite nanoparticles that prepared by liquid phase reduction method under 40 kHz and 150 W ultrasonic irradiation were obviously modified. The optimized experimental conditions were obtained and up to 92.08% of 4-CP was removed in 300 min with Pd/Fe dosage 4.00 g/L, mass fraction of Pd in Pd/Fe@SiO2 composite nanoparticles 0.40% (wt/%), 2.5mL TEOS per gram of Pd/Fe, reaction temperature 30°C, initial pH value 3.0,and initial 4-CP concentration 30mg/L. The degradation of 4-CP followed pseudo-first-order kinetics reaction and the apparent pseudo-first-order kinetics constants k was 2.98×10 min. |
