| Abstract | ||
| Used nanoparticles of ZnO with liquid phase and prepared 100 mJ, and the number of pulses (300,600) pulse using (PLA). To remove phenols dissolved in water at a concentration of 100 mg.mol-1 and at different temperatures (25,35,45,55) ºС. The study confirmed that the percentage of purification of water polluted with phenol decreases with the increase of temperature at the concentration of nanoparticles prepared (300) pulses, but when the concentration of nanoparticles prepared with 600 pulses, the heat factor is not effective, and increase the rate of purification (adsorption efficiency) to 98.427%. The study of thermodynamic functions indicates that the type of adsorption between nanoparticles used and phenol is physical, automatic, heat-emitting and very efficient. | ||
