Sonocatalyst degradation of catechol from aqueous solution using magnesium oxide nanoparticles

<p>Catechol is a highly toxic phenolic organic compound used in various industries such as refineries, toxics, dyes and plastics. When this enters the environment, it can have negative effects on human health ecosystem. In study-removed pyrocatechol from aqueous solutions using sonocatalytic process magnesium oxide nanoparticles. The study was conducted laboratory scale of pH, catalyst dose, initial concentration reaction time under 130-kHz ultrasonic waves degradation were investigated. maximum efficiency optimal conditions (i.e. 25 mg / l, pH = 3, nanoparticle dose 500 l after contact 60 min) 92%. results showed that follows first order pseudokinetics. show presence nanoparticles has high removing catechol solutions</p>
