高碘酸钠对杂多酸复合脱硫体系吸收-再生性能的影响

Effect of Sodium Periodate on Adsorption and Regeneration of Heteropolyacid Complex Desulfuration System

采用电位示踪技术研究高碘酸钠对磷钼酸钠及其构成的复配脱硫体系(Na3PMo12O40-NaVO3-Na2CO3-NaCl)再生性能的影响。实验结果表明,高碘酸钠的加入提高了脱硫体系的吸收性能和再生性能。吸收及再生过程中,高碘酸钠起催化剂的作用,一方面氧化被还原的磷钼酸钠,一方面辅助吸收硫化氢。

Effects of sodium periodate on the regeneration of sodium phosphmolybdate and its complex desulfuration system (Na 3PMo 12 O 40 -NaVO 3-Na 2CO 3-NaCl) were investigated by electrode potential track.Adding sodium periodate increases adsorption and regeneration ability of the system.Sodium periodate acts as a catalyst which oxidizes sodium phosphomolybdate and absorbs hydrogen sulphide.
