Hydrogen Sulfide (H2S)

Sigogi na fasaha

Hydrogen sulfide wani sinadari ne mara tsari wanda ke da tsarin kwayoyin halitta na H2S kuma nauyin kwayoyin halitta na 34.076. A ƙarƙashin yanayi na yau da kullun, iskar acid ce mai ƙonewa. Ba ta da launi kuma tana da ƙamshin ƙwai da suka ruɓe a ƙarancin yawan guba. Maganin ruwa shine hydrogen sulfuric acid, wanda ya fi rauni fiye da carbonic acid, amma ya fi ƙarfi fiye da boric acid. Hydrogen sulfide yana narkewa a cikin ruwa, yana narkewa cikin sauƙi a cikin barasa, mai narkewar mai da ɗanyen mai, kuma halayen sinadarai ba su da ƙarfi. Hydrogen sulfide sinadari ne mai ƙonewa da haɗari. Idan aka haɗa shi da iska, yana iya samar da cakuda mai fashewa. Yana iya haifar da ƙonewa da fashewa lokacin da aka fallasa shi ga harshen wuta da zafi mai zafi. Hakanan abu ne mai tsanani kuma mai guba sosai. Hydrogen sulfide mai ƙarancin yawan taro yana da tasiri ga idanu, tsarin numfashi da tsarin jijiyoyi na tsakiya. Shaƙa ƙaramin adadin hydrogen sulfide mai yawan taro na iya zama mai mutuwa cikin ɗan gajeren lokaci. Ana amfani da shi wajen kera phosphors na roba, electroluminescence, photoconductors, photoelectric exposure mitoci, da sauransu. Maganin rage hada sinadarai. Ana amfani da shi wajen tace ƙarfe, magungunan kashe kwari, magani, sake farfaɗo da abubuwan kara kuzari. Reagents na gabaɗaya. Shirye-shiryen sulfide daban-daban. Ana amfani da shi wajen kera sulfides marasa tsari, kuma ana amfani da shi wajen nazarin sinadarai kamar gano ions na ƙarfe. Ana amfani da hydrogen sulfide mai tsafta a semiconductor da sauran fannoni. Haka kuma ana iya amfani da shi a masana'antar sinadarai ta tsaro ta ƙasa, magungunan magunguna da magungunan kashe kwari, gyaran ƙarfe mara ƙarfe da gyaran saman ƙarfe, ana amfani da shi wajen shirya iskar gas ta yau da kullun, iskar gas mai daidaitawa, da nazarin sinadarai kamar gano ions na ƙarfe. Wani muhimmin abu don kera kayan gani na infrared. Gargaɗin ajiya: A adana a cikin ma'ajiyar ajiya mai sanyi, mai iska. A ajiye shi nesa da hanyoyin wuta da zafi. Yanayin zafin ajiya bai kamata ya wuce 30°C ba. A rufe akwati sosai. Ya kamata a adana shi daban da oxidants da alkalis, kuma a guji ajiya mai gauraya. Yi amfani da hasken da ba ya fashewa da wuraren samun iska. An haramta amfani da kayan aikin injiniya da kayan aikin da ke iya haifar da tartsatsin wuta. Ya kamata a sanya kayan aikin gaggawa na magance ɓullar ruwa a wurin ajiyar.

Aikace-aikace:

① Samar da mahaɗan thioorganic:

Ana samar da wasu sinadarai na organosulfur ta amfani da hydrogen sulfide. Waɗannan sun haɗa da methanethiol, ethanethiol, da thioglycolic acid.

②Sinadarin nazari:

Tsawon sama da ƙarni guda, hydrogen sulfide yana da mahimmanci a cikin ilmin sunadarai na nazari, a cikin nazarin inorganic na inganci na ions na ƙarfe.

③Mai gabatarwa ga ƙarfe sulfide:

Kamar yadda aka nuna a sama, yawancin ions na ƙarfe suna amsawa da hydrogen sulfide don samar da sulfide na ƙarfe masu dacewa.

④Aikace-aikace daban-daban:

Ana amfani da hydrogen sulfide don raba deuterium oxide, ko ruwa mai nauyi, daga ruwan yau da kullun ta hanyar tsarin Girdler sulfide.
