Using chelated iron ions as catalysts and alkaline solutions as absorbers, the goal of hydrogen sulfide removal is achieved. The principle of chemical reaction is divided into two parts: desulfurization absorption process and regeneration process.
1、吸收氧化總反應方程式：
1. The total reaction equation for absorption oxidation:
H2S(g)+2Fe3+(L)→2H+(L)+S↓+2Fe2+(L)
H2S(g)+2Fe3+(L)→2H+(L)+S↓+2Fe2+(L)
2、再生過程：為恢復溶液吸收硫化氫的能力，就對溶液進行再生，再生過程主要發(fā)生氧化析硫反應：
2. Regeneration process: In order to restore the solution's ability to absorb hydrogen sulfide, it is necessary to regenerate the solution. The regeneration process mainly involves oxidation and sulfur evolution reaction:
1/2O2(g)+H2O(L)+2Fe2+(L)→2OH-(L)+2Fe3+(L)
1/2O2(g)+H2O(L)+2Fe2+(L)→2OH-(L)+2Fe3+(L)
