Detalhes bibliográficos
Resumo:This study investigates the potential of ultrasonic-assisted (20kHz and 65±5 W) adsorption processes in wastewater treatment. The enhanced effects of ultrasonic cavitation on Ciprofloxacin and Cu (II) removal efficiency by adsorption on a Kaolinite and municipal organic waste compost (OC) adsorption media were studied and discussed. Experimental results indicate that within the first minute, more than 95% of the maximum adsorption of Cu (II) and CIP was achieved with OC. Also, the maximum retention of Cu (II) by the assisted method outperformed the traditional adsorption process by 440% after 1 minute and 74% by 30 minutes. These good results were not observed in the US-Kaolinite experiments, where the removal did not exceed the standard process. This work suggests that ultrasonic-assisted cavitation can enhance the adsorption of some environmental pollutants on an organic compost media, providing insights into new ways to provide control and/or retention of contaminants of emerging concern.
