HIGHLIGHTS

  • The solution of peroxo phosphomolybdic acid was used for H2S removal.
  • The H2S removal efficiency can keep 100% for 10 h through two-stage absorption.
  • The absorbent can be regenerated simply by adding a small amount of H2O2 solution.
  • The ultimate oxidation product of H2S is SO42–.

 

ABSTRACT


A new method of removing H2S using the solution of peroxo phosphomolybdic acid was developed. The results showed that the solution of peroxo phosphomolybdic acid had perfect capacity for H2S removal. A H2S removal efficiency of 100% for 10 h could be achieved by using two-stage absorption with an absorbent concentration of 0.02 mol L–1. The effect of temperature, concentration of peroxo phosphomolybdic acid and H2S on H2S removal was explored. According to the results, a high absorbent concentration, low H2S concentration and slightly excessive H2O2 are beneficial to H2S removal under relatively low temperature. The absorbent showed a perfect regeneration performance, and could be reactivated simply by adding a few drops of 30% H2O2 solution. The X-ray photoelectron spectra showed that the H2S was oxidized to SO42– finally.
