He huānga kore-whakarewa te whanariki, ko te tohu matū S me te tau ngota he 16. Ko te whanariki parakore he tioata kōwhai, e mōhiotia ana ko te whanariki, ko te whanariki kōwhai rānei. Kāore te whanariki huānga e wairewa i roto i te wai, he paku wairewa i roto i te etanoru, ā, he ngāwari te wairewa i roto i te waro disulfideCS.2.
1. Ngā āhuatanga ā-tinana
- He tioata kōwhai mārama te whanariki, kāore he kakara, kāore hoki he reka.
- He maha ngā allotropes o te whanariki, ā, he mea tito katoa ēnei i te S8ngā ngota porowhita. Ko ngā mea tino noa ko te whanariki orthorhomb (e mōhiotia ana ko te whanariki rhombic, α-whanariki) me te whanariki monoclinic (e mōhiotia ana ko te β-whanariki).
- He momo pūmau te whanariki Orthorhombic o te whanariki, ā, ina whakamahanatia ki te 100 °C, ka taea te whakamatao kia whiwhi ai i te whanariki monoclinic. Ko te pāmahana whakawhiti i waenga i te whanariki orthorhombic me te whanariki monoclinic he 95.6 °C. Ko te whanariki orhombic anake te momo pūmau o te whanariki i te pāmahana rūma. Ko tōna āhua parakore he kōwhai-kakariki (ko te whanariki e hokona ana i te mākete he ahua kōwhai ake nā te mea he iti noa te cycloheptasulfur). Ko te whanariki Orthorhombic he mea kore e wairewa i roto i te wai, he ngoikore te kawe wera, ā, he pai te ārai hiko.
- Ko te whanariki monoclinic ko ngā tioata rite ki te ngira e toe ana i muri i te rewa o te whanariki me te ringihanga o te wai taikaha. Ko te whanariki orthorhombic whanariki monoclinic he momo whanariki taketake i ngā pāmahana rerekē. Ka pumau noa te whanariki monoclinic i runga ake i te 95.6 ℃, ā, i te pāmahana, ka huri mārire hei whanariki orthorhombic. Ko te ira rewa o te whanariki orthorhombic he 112.8 ℃, ko te ira rewa o te whanariki monoclinic he 119 ℃. He tino wairewa ngā mea e rua i roto i te CS2.
- Kei reira anō te whanariki pīwariwari. He totoka pīwariwari te whanariki pīwariwari, he kōwhai pouri, he iti ake te wairewa i roto i te waro disulfide i ērā atu allotropes whanariki. Kāore e wairewa i roto i te wai, ā, he paku wairewa i roto i te waipiro. Ki te ringihia wawetia te whanariki rewa ki roto i te wai matao, ka noho te whanariki mekameka roa hei whanariki pīwariwari pumau, ka taea te totoro. Heoi, ka whakapakeke i roto i te wā, ka huri hei whanariki monoclinic.
2. Ngā āhuatanga matū
- Ka taea e te whanariki te tahu i te rangi, ka tauhohe ki te hāora hei hanga i te hauhā whanariki (SO₂) hau.
- Ka tauhohe te whanariki ki ngā halogen katoa ina whakamahanatia. Ka tahuna ki te fluorine hei hanga i te whanariki hexafluoride. Ka tauhohe te whanariki wai ki te chlorine hei hanga i te disulfur dichloride tino whakapataritari (S2Cl2Ka taea te hanga i tētahi ranunga taurite kei roto ko te whanariki dichloride whero (SCl) ina nui rawa te chlorine, ā, he whakakorikori, pērā i te FeCl3SnI rānei4,e whakamahia ana.
- Ka taea e te whanariki te tauhohe ki te wai wera o te pāhare pākawa waro (KOH) hei hanga i te pāhare pākawa waro me te pāhare pākawa thiosulfate.
- Kāore te whanariki e tauhohe ki te wai me ngā waikawa kore-waikura. Ka tauhohe te whanariki ki te waikawa hauota wera me te waikawa whanariki kukū, ā, ka taea te waikura hei waikawa whanariki me te hauhā whanariki.

- Te whakamahinga ahumahi
Ko ngā whakamahinga matua o te whanariki ko te hanga i ngā matū whanariki pērā i te waikawa whanariki, ngā whanariki, ngā thiosulfates, ngā ocyanates, te hauhā whanariki, te waro disulfide, te disulfur dichloride, te trichlorosulfonated phosphorus, te phosphorus sulf, me ngā whakarewa sulfide. Neke atu i te 80% o te whakamahinga whanariki ā-tau o te ao e whakamahia ana ki te hanga waikawa whanariki. He whānuitia hoki te whakamahinga o te whanariki ki te hanga rapa whakamomona. Ina whakamomonahia te rapa mata ki roto i te rapa whakamomona, ka whiwhi i te ngāwari teitei, te ātete wera i te kaha kume, me te kore e wairewa i roto i ngā whakarewa waro. Ko te nuinga o ngā hua rapa he mea hanga ki te rapa whakamomona, e hangaia ana mā te tauhohe i te rapa mata me ngā whakatere i ētahi pāmahana me ngā pēhanga. E hiahiatia ana hoki te whanariki ki te hanga paura pango me ngā mati, ā, ko tētahi o ngā mea matua mō ngā ahi ahi. Hei tāpiri, ka taea te whakamahi i te whanariki ki te hanga tae me ngā tae whakamomona. Hei tauira, mā te whakawera i te ranunga o te kaolin, te waro, te whanariki, te whenua diatomaceous, te paura quartz rānei ka taea te whakaputa i te tae kikorangi e kiia nei ko te ultramarine. Ka pau hoki i te umanga mā te wai me te umanga rongoā tētahi wāhanga o te whanariki.
- Te whakamahinga hauora
Ko te whanariki tētahi o ngā kai o roto i te maha o ngā rongoā mate kiri. Hei tauira, ka whakamahanahia te hinu tung ki te whanariki kia whakapūhā ki te waikawa whanariki, kātahi ka whakakorengia ki te wai haukini kia puta ai te hinu tung kua whakapūhā. He pānga ārai-mumura me te whakaora te hinu 10% i hangaia mai i tēnei hinu, ā, ka taea te whakamahi hei rongoā i ngā mumura me ngā pupuhi kiri.
