摘　　要：综合日本化学技术所的吸收—电解法和Doyle等人所说的氧化再生反应,提出了FeC l3溶液吸收、O2氧化、由H2S回收硫黄的方法;并且在吸收液中加入少量硝酸,以便提高S2-被氧化的速度。采用二级吸收—氧化流程,总的吸收率可达98%以上。The method of recovery sulfur from H2 S through FeCl3 solution absorption - oxygen oxidation is put forward,in comparison to absorption electrolysis method in Japan chemical institute and Doyle＇s oxidation regeneration reaction. Besides,adding a little HNO3 in the absorption liquid so as to improve S2- oxidative speed. Total absorptivity can be up to 98% using second - order absorption - oxidation process.
