Production o hauwai sulfide, ona āhuatanga, te whakamahi o

I roto i tēnei tuhinga ka titiro tatou ki te whiwhi he whanariki i te hauwai pūngāwhā. He āta titiro ki te āhuatanga ōkiko me te matū o te taonga.

hanganga

I roto i te tikanga ki te tātari i te fariiraa matua o hauwai sulfide, he mea e tika ana ki te kitea i roto i nga āhuatanga o tona hanganga. Hei wāhanga o te taonga kei tetahi ngota whanariki, me te rua hauwai. He kore-konganuku ratou, na i waenganui i nga mea timatanga i hanga kotuari here neke. Ko te hanganga koki o te sulfide hauwai. hanga te reira i te koki o 92 nekehanga i waenganui i te whanariki me te hauwai, i te mea paku iti ake i roto i te wai.

ngā āhuatanga ōkiko

Hauwai sulfide kakara rite hua pirau, he maheni ki te katoa. I raro i ngā āhuatanga noa, ko te taonga i roto i te āhua haurehu waihā. He kahore tae, he ruarua wairewa i roto i te wai, paitini. I te toharite, ka tareka i te 20 degrees 2.4 hauwai sulfide i roto i te rōrahi wai. I hauwai whakakitea wai sulfide iti waikawa āhuatanga kaihoko dissociation puta stepwise. He mōrearea sulfide hauwai paitini ara i roto i pota iti. Ihirangi o te rangi tata 0.1 ōrau hauwai sulfide arata'i ki pāpāngia o te pokapū romahā ki mate o te mahara. Hei tauira, te taiao o rongonui Pliniy Starshy mate i roto i te BC 79 rau, ko reira hauwai sulfide, i hanga nei i roto i te hūnga o Vesuve.

Ko te take mo te mahi o te hauwai sulfide paihana i roto i tona pāhekoheko matū ki pūtoto i roto i te toto. Iron roto i roto i tenei pūmua hanga he sulfide ki hauwai sulfide.

whakaaro te kukū tīkina mōrahi o te sulfide hauwai i roto i te rangi e ki kia 0.01 mg / l. Ka rite ki te raau inhalation whakamahia o hāora parakore ranei rangi, i roto i nei hanganga i reira ko te nui iti o te māota.

Te mahi ki te sulfide hauwai titau tautukunga ki etahi ture haumaru. whakamātau katoa mo tenei taonga haurehu waihā kawea i roto i ngā pūrere hiri me kāpata fume.

Methods o te whakaputa sulfide hauwai

He aha te whiwhi i te sulfide hauwai i roto i te taiwhanga? Ko te kotahi tino noa ko te pāhekoheko o te hauwai ki te whanariki. E pā ana tēnei tauhohenga matū ki te pūhui kawea e te atu i roto i te autahu'araa fume.

I tua atu, ko te whakarite me te pea te sulfide hauwai i roto i te utu i waenganui i te pūngāwhā totoka rino (2) me te otinga o te waikawa pungatara pūmāota ranei. Hei whiwhi i te hua taua, i roto i te ipuipu he nui ki te tango i te torutoru mongamonga o whanariki, e kore e nui ake te rahi o te pea. I tua atu, ko te ngongo (hawhe rōrahi) i tapiritia te otinga waikawa, katia te ngongo kohu te. whakanohoia ana te pūrere te i raro i te araa, he wera te ngongo. tahi te tauhohenga matū e tuku o mirumiru hau. Tenei taea ki a koe te hanga hauwai sulfide ki te whiwhi i te nui o te rauemi rawaka kia whiriwhiria o ona āhuatanga matū.

He aha te tahi atu mau rave'a e? I roto i te faaineineraa taiwhanga o hauwai pūngāwhā e whakaaetia ai e te tauhohe i konganuku rino (i raro i te autahu'araa) ki te whanariki, tioata, aru i te tauhohe o te sulfide ki te waikawa pungatara.

āhuatanga matū

tauhohe hauwai sulfide ki te hāora i roto i te rangi, e ngiha ai he tae kikorangi. I roto i te take o oti hua ngingiha tauhohe he pūngāwhā hāora rua (4) me te wai. Hoatu e te hau oumu ko te waikura waikawa, i roto i te otinga, hanga ana e ia he ngoikore waikawa sulfurous, tae puru pepa tohu waikawa whero.

I roto i te take o te iti moni o hauwai sulfide, tioata i hanga whanariki. whakaaro ana tēnei tukanga ko te tukanga ahumahi mō te whakaputa whanariki i hauwai sulfide parakore.

I roto i tenei matū tāutuhia me resilience pai. E whakaaturia ana ratou, mo te tauira, mā te tauhohe i ki tai, kōnakonako. I roto i te tikanga ki te whakahaere i roto i vitro tauhohenga rite i roto i ipuipu ki māota me te pūkeha ringihia otinga pūngāwhā, i kitea discoloration. Ka rite ki te hua tauhohenga i kitea te hanganga o tioata whanariki.

A, no te te tauhohenga matū o te hauwai sulfide ki te wai te hanganga o te hauwai honowai te māraa H3O +.

Ka taea e te hauwai sulfide hanga e rua ngā momo o ngā pūhui: sulfides (tote reo) me hydrosulfides (tote waikawa).

I roto i te whenua alkali me kawakore sulfides whakarewa he pūhui taekore. I roto i te konganuku taimaha (parahi, nika, mata), he mangu ratou. sulfide konupora he tae māwhero. E rave rahi o te tote e kore e memeha i roto i te wai.

tauhohenga kounga ki sulfides kitea ngā ki otinga parahi pūkawa ngāwha (2). Ko te hua o taua pāhekoheko he hohenga mangu o te parahi pūngāwhā (2).

mutunga

I roto i te natura, ko tenei taonga i roto i te puna kohuke, hau puia. Tenei pūhui Ko te hua o te pirau o te tipu me te kararehe kaiao, titore reira te kakara āhuatanga o te hauwai sulfide. sulfides Natural kitea i roto i te hanganga o konganuku onge i te metallurgy o ratou riro huānga e tika ana. He mea nui ki te mahara e te sulfide hauwai ko te taonga kaha paitini.
