Uranium removal from uranium plant wastewater using zero-valent iron in an ultrasonicfield was investigated. Batch experiments designed by the response surface methodology(RSM) were conducted to study the effects of pH, ultrasonic reaction time, and dosage ofzero-valent iron on uranium removal efficiency. From the experimental data obtained inthis work, it was found that the ultrasonic method employing zero-valent iron powdereffectively removes uranium from uranium plant wastewater with a uranium concentrationof 2,772.23 mg/L. The pH ranges widely from 3 to 7 in the ultrasonic field, and theprediction model obtained by the RSM has good agreement with the experimental results.
