摘要

Freshly generated magnesium hydroxide (FGMH), produced by adding water-soluble magnesium salts to highly alkaline solutions, was used to remove anionic surfactant petroleum sulfonate (PS) from aqueous solutions. Adsorption experiments were carried out to investigate the effects of pH, adsorbent dosage, contact time, PS concentration, and temperature. The results showed that FGMH displayed excellent treatment efficiency for PS in the pH range 12.0-13.0. The maximum PS removal efficiency was reached within 60 s. The best dosage of magnesium chloride was 2.0 g/L. The adsorption capacity of FGMH for PS decreased as the temperature increased from 303 K to 333 K. The adsorption process was exothermic. The removal mechanism of PS by FGMH may be a coagulation-adsorption process involving a combination of flocculation, adsorption, charge neutralization, and netting catch affection. The results of this study showed that FGMH can be effectively used to treat surfactant wastewaters.
