1. Tikanga absorption:
Horoihia te hauwai sulfide ki te wairewa sulfide alkali (te wairewa houra wai ranei).Na te mea he paitini te hauwai sulfide, me whakahaere te tauhohenga absorption i raro i te pehanga kino.Hei aukati i te nui o te parahanga o te hau e te hauwai sulfide i roto i te hau whakapau, he maha nga kaihoroi e whakahaerehia ana i roto i nga raupapa i roto i te whakaputanga, a ka heke te ihirangi hauwai sulfide ki te taumata iti i muri i te whakaurunga o nga wa katoa.Ko te wai absorption ka kukū ki te tiki konutai hydrosulfide.Ko tōna tātai matū:
H2S+NaOH→NaHS+H2O
H2S+Na2S→2NaHS

2. Ka tauhohe te konutai alkoxide ki te hauwai sulfide maroke hei whakarite i te konutai hydrosulfide:
I roto i te ipu 150mL me te putorino manga, tāpirihia te 20mL o te waiwaro tino katahi ano ka marewa me te 2g o nga konganuku konutai konutai me te mata maeneene me te kore he paparanga waikura, whakaurua he kondenser reflux me te putorino whakamaroke ki runga i te ipu, ka hiritia te paipa manga i te tuatahi.Ka tohe te konutai alkoxide, tāpirihia te 40 ml o te waihā pūmau ki roto i ngā puranga kia rewa katoa te konutai alkoxide.
Whakauruhia he ngongo karaihe ki raro o te otinga ma roto i te putorino manga, ka tuku hau hauwai sulfide maroke (kia mahara karekau he hau e uru ki roto i te ipu ki te putorino manga kua hiri).Whakakukuria te otinga.I tātarihia te wairewa hei tango i te para.I rongoa te filtrate i roto i te ipu koeko maroke, me te 50 mL o te tino etera i tapirihia, a he nui te nui o te NaHS ma i tohe tonu.Tata ki te 110 mL o te ether e hiahiatia ana.Ka tere te tarai i te wai, ka horoi kia 2-3 nga wa ki te ether tino, ka maroke, ka maka ki roto i te desiccator korehau.Ka taea e te ma o te hua te tae ki te purenga tātari.Ki te hiahiatia te NaHS parakore ake, ka taea te rewa i roto i te waihano me te whakahiato ki te etera.

3.Sodium hydrosulfide wai:
Whakarewahia te konutai sulfide nonahydrate ki roto i te wai parai hou, ka waimeha ki te wairewa 13% Na2S (W/V).14 karamu o te konutai bicarbonate i tapirihia ki te wairewa i runga ake nei (100 mL) me te whakakorikori me raro iho i te 20°C, ka rewa tonu me te whakawera.I muri mai ka tapirihia te 100 ml o te mewaro me te whakakorikori me raro iho i te 20°C.I tenei wa ka rere ke ano te werawera, ka tata katoa o te konutai warowaikawa tioata ka rere tonu.Whai muri i te 0 meneti, ka tātarihia te ranunga ki te momi, ka horoia te toenga ki te methanol (50 mL) etahi wahanga.Ko te filtrate kaua e iti iho i te 9 g o te konutai hydrosulfide me te kore e neke ake i te 0.6 paiheneti o te konutai warowaiha.Ko nga kohinga o nga mea e rua he 3.5 karamu me te 0.2 karamu mo ia 100 ml o te otinga.

I te nuinga o te wa ka whakareri maatau ma te tango i te hauwai sulfide me te wairewa konutai waikawa.Ina he 70% te ihirangi (te hautau papatipu o te konutai hydrosulfide), he waikawa, he tawerewere te ahua;Mena he iti ake te ihirangi, he hua wai, e toru Hydrate.
