1. Ko te tikanga whakaiti waro, ka konatunatuahia te mirabilite me te waro parapara ki te tauwehenga o te 100: (21-22.5) (te tauwehenga taumaha) me te calcined me te whakaheke i te pāmahana teitei o te 800-1100 °C, a ka whakamataohia te hua ka whakamataohia me te wera. ka rewa ki roto i te wai ki te waimeha reito , i muri i te tu mo te whakamaarama, ko te wairewa rei to runga ka kukū ki te tiki konutai sulfide totoka. Ka whiwhihia te hua o te konutai sulfide i runga i te papa (papa ranei) na roto i te waka whakawhiti, te papaa (me te whakamaarama ranei)
Te whārite tauhohenga matū: Na2SO4+2C→Na2S+2CO2

Tikanga 2.Absorption: 380-420 g/L konutai wairewa wairewa e whakamahia ana ki te mimiti hau ururua kei roto H2S>85% hauwai sulfide, a ka whakaeto te hua whiwhi ka kukū ki te whiwhi konutai sulfide hua oti.
Te whārite tauhohenga matū: H2S+2NaOH→Na2S+2H2O

3. Tikanga Barium sulfide, ka taea te hoko konutai sulfide hei hua-a-taapiri ina whakamahia te konutai pūkawa ngāwha me te barium sulfide mō te tauhohenga metathesis ki te whakarite i te waikura pākawa ngāwha. Ko tera
Te whārite tauhohenga matū: BaS+Na2SO4→Na2S+BaSO4↓

4. Ko te tikanga whakaheke hau, i te aroaro o te whakakorikori rino, ka tauhohehia te hauwai (te waro monoxide ranei, te hau kaihanga, te hau mewaro) ki te konutai pūkawa ngāwha i roto i te oumu koropupū, me te konutai konutai konutai konutai (kei roto Na2S 95%) ka taea. kia whiwhi. ~97%).
Whārite tauhohenga matū:
Na2SO4+4CO→Na2S+4CO2
Na2SO4+4H2→Na2S+4H2O

5.Te tikanga whakaputa, ka whakamahia e te tikanga whakamahine te otinga konutai sulfide me te kukū mo te 4% i te hua-hua i roto i te mahi o te whakaputa i te barium sulfate hei rauemi mata. I muri i te pana ki roto i te whakaetonga hua-rua ki te whakaeto ki te 23%, ka uru ki roto i te taika whakakorikori hei tango i te rino. , I muri i te maimoatanga tango waro, ka panaia te rei ki roto i te whakaetonga (i hanga mai i nga mea nickel parakore) ki te whakaeto i te rei kia tae ki te kukū, ka tukuna ki te miihini papa whakamahana wai pahū.

E rua nga tikanga e whakamahia ana e to maatau wheketere, te tikanga whakaheke waro me te tikanga barium sulfide, hei whakaputa i nga tawerewere whero konutai sulfide me nga tawerewere kowhai.
