Effect of the coexistence of SO and PO on the adsorption performance of zeolite-loaded FeOOH@ZnO for S.

The present study deals with the synthesis of zeolite-loaded FeOOH@ZnO by hydrothermal method and investigates the effects of coexisting SO and PO ions in the aqueous solution on the adsorption performance for S. The results showed that the HNO-modified zeolite loaded with FeOOH@ZnO (FeOOH@ZnO/HZ) resulted in a maximum S removal rate of ≈98%. The adsorbent's performance on removing S was significantly enhanced, compared with NaOH and ZnCl-modified zeolites loaded with FeOOH@ZnO, and the adsorption was proved to be a heat-absorbing process.
