Experimental Study on the Recovery of Sulfur Hexafluoride Adsorbent based on Ultrasound Cavitation Effect

This paper proposes a regeneration and innocent treatment method based on ultrasound cavitation effect for decommissioned sulfur hexafluoride adsorbent. Compared with traditional methods, this method owns lower cost, higher efficiency and better effects. The proposed method mainly regenerates the adsorbent through ultrasound cavitation and conducts innocent treatment of desorbed substance in alkali solution to eliminate the harm to environment. According to this method, it is determined through the experimental study that the optimal treatment time of decommissioned adsorbent with ultrasound cavitation is 20min and the adsorption capacity of renewable adsorbent can be recovered to 85% to 90% which owns extremely high application value.
