Magnesium sulfat utawa magnesium sulphate (ing basa Inggris Britania) minangka senyawa kimia, uyah kanthi rumus MgSO4, kalebu kation magnesium Mg2+ (20,19% kanthi massa) lan anion sulfat SO42-. Iki minangka kristal putih padhet, larut ing banyu nanging ora ana ing etanol. Magnesium sulfat biasané ditemoni ing wangun saka hydrate MgSO4·nH2O ,kanggo macem-macem nilai n antara 1 lan 11. Sing paling umum yaiku MgSO4·7H2O, dikenal minangka uyah Epsom, sing minangka bahan kimia rumah tangga sing akéh nggunakaké tradisional, kalebu uyah adus.[1]

Sampel magnesium sulfat

Panggunaan utama magnesium sulfat yaiku ing tetanén, kanggo mbeneraké lemah sing kurang magnesium (nutrisi tanduran penting). Monohidrat disenengi kanggo nggunakaké iki; ing pertengahan taun 1970-an, prodhuksi dadi 2,3 yuta ton saben taun.[2] Wangun anhidrat lan pirang-pirang hidrat ing alam minangka mineral, lan uyah minangka komponén penting banyu saka sawetara tuk.

Sipat fisik magnesium sulfat besut

Relaksasi magnesium sulfat minangka mekanisme utama sing nyebabaké panyerepan swara ing banyu laut kanthi frekuensi ing ndhuwur 10 kHz [3] ( energi akustik diowahi dadi énégi termal ). Frekuensi ngisor kurang diserap uyah, saengga swara frekuensi kurang luwih adoh ing sagara. Asam borat lan magnesium karbonat uga nyumbang kanggo nyerap.[4]

Magnesium sulfat kanggo médhis

Médhis besut

Magnesium sulfat digunakaké ing njaba (minangka uyah Epsom) lan njero. Pemanfaatan eksternal utama yaiku formulasi minangka uyah adus, utamané kanggo sikil kanggo ngenthengaké sikil sing lara. Siram kaya mengkene uga nyenengaké lan nyepetaké pemulihan otot, lara, utawa cilaka. Nanging, klaim kasebut durung dikonfirmasi kanthi ilmiah. Keuntungan utama uyah yaiku kosmetik: ngalangi kerut kulit sauntara amarga dicelupaké kanthi suwe ing banyu kosong.[1][5] Iki uga komponén umum saka solusi sing digunakaké ing tank isolasi.

Ing Inggris, obat sing ngemot magnesium sulfat lan fenol, sing diarani "drawing paste", diklaim migunani kanggo bisul cilik utawa infeksi lokal [6] lan ngilangi serpihan.[7] Secara internal, magnesium sulfat bisa uga ditrapaké kanthi rute oral, napas, utawa intravena. Panggunaan internal kalebu terapi panggantos kanggo kurang magnesium,[8] perawatan aritmia akut lan abot,[9] minangka bronkodilator ing perawatan panandhang asma,[10] lan nyegah eklampsia.[11]

Pertanian besut

Ing tetanén, magnesium sulfat digunakaké kanggo nambah isi magnesium utawa belerang ing lemah . Umume digunakaké kanggo tanduran pot, utawa kanggo tanduran sing lapar magnesium kayata kentang, tomat, wortel, mrica, jeruk nipis, lan mawar. Keuntungan magnesium sulfat tinimbang parubahan lemah magnesium liyané (kayata jeruk  dolomit ) yaiku kelarutan sing dhuwur, sing uga ngidini pilihan panganan foliar. Solusi magnesium sulfat uga meh pH netral, dibandhingaké karo uyah alkalin magnesium kaya sing ditemokaké ing watu gamping; mula, panggunaan magnesium sulfat minangka sumber magnesium kanggo lemah ora bakal ngowahi pH lemah kanthi signifikan.[12]

Magnesium sulfat sacara historis digunakaké minangka perawatan kanggo keracunan timah sadurungé pangembangan terapi chelasi, amarga samesthiné manawa ana timbal sing dicerna bakal diencerké dening magnesium sulfat lan banjur diresiki saka sistem pencernaan.[13] Aplikasi iki nuduhaké panggunaan nyebar ing kalangan dokter hewan sajrone wiwitan abad kaping 20 nganti pertengahan; Uyah epsom wis kasedhiya ing pirang-pirang peternakan kanggo digunakaké ing tetanén, lan asring diwènèhaké ing perawatan kéwan tani sing tanpa sengaja ngonsumsi timah.[14][15]

Pangan besut

Magnesium sulfat digunakaké minangka uyah kanggo nggawé bir.[16] Iki uga bisa digunakaké minangka koagulan kanggo nggawé tahu.[17]

Akuaria besut

Heptahidrat magnesium sulfat uga digunakaké kanggo njaga konsentrasi magnesium ing akuarium laut sing ngemot karang karang sing akéh banget, amarga alon-alon ilang ing proses kalsifikasi. Ing akuarium laut kekurangan magnesium, konsentrasi kalsium lan alkalinitas angel banget dikontrol amarga ora cukup magnesium kanggo stabil ion kasebut ing banyu asin lan nyegah udan spontan dadi kalsium karbonat.[18]

The treatment of acute lead-poisoning consists in the evacuation of the stomach, if necessary, the exhibition of the sulphate of sodium or of magnesium, and the meeting of the indications as they arrive. The Epsom and Glauber's salts act as chemical antidotes, by precipitating the insoluble sulphate of lead, and also, if in excess, empty the bowel of the compound formed.

Udall (1) suggests sodium citrate as of some value together with Epsom salts which will bring about a precipitation of the lead in the form of an insoluble compound. Nelson (3) reported a case that survived following the use of a 20% magnesium sulphate solution intravenously, subcutaneously and orally. McIntosh (5) has suggested that purgative doses of Epsom salts may be effective in combining with the lead and overcoming the toxicity.

The specific antidotes to metal poisoning had not been discovered and the only thing which sometimes did a bit of good was magnesium sulphate which caused the precipitation of insoluble lead sulphate. The homely term for magnesium sulphate is, of course, epsom salts.
