ZAMCH

ZAMCH, zok, kristallogidrati namakhoi duchandi sulfat, formulai umumiashon Me2ISO4 • Me2III(SO4)3 • 24H2O yo MeINeIII(SO4)2 • 12H2O, dar injo MeI, MeIII – kationi metallhoi yak va sevalenta (mas., Z.-i alyuminiyu kaliydor K2SO4 • Al2(SO4)3 • 24H2O. Elementhoi nodirzamini sevalenta Z. hosil namekunand. Z. dar sharoiti muqarrari sobit boshad ham, hangomi garm kardan ba Z.-i pukhta mubaddal meshavad. Z. dar ob purra hal meshavad. CHunin mahlul tami tursh va khosiyati karakhtkunanda dorad. Z.-ro az omezishi mahlulhoi garmi sulfati metallhoi yak va sevalenta hosil mekunand. Kristallhoi Z. hangomi khunukshavi judo meshavand. Z.-i alyuminiyu kaliydor va khromu kaliydor [K2SO4 • Cr2(SO4)3 • 24H2O]-ro beshtar istifoda mebarand. Onhoro dar suratgiri, charmgari (chun vositai dabbogi), olkori (chun vositai tezobdihanda hangomi rang kardani mato va g.) istifoda mebarand.
Ba aqidai tabiboni khalqi zokro sukhta chun surma ba chashm kashand, gushahoi chashmro az khilm pok mekunad; agar onro bo asal sirishta kashand, gafsi va dagalii pilki chashmro isloh menamoyad. Agar onro ba vositai naycha ba daruni bini pur kunand, khuni biniro man mesozad. Zokro os karda bo obi kashniz sirishta bimoland, surkhbod, qutur va khorishakro davo meshavad, zakhmhoi tarro karakhsh mebandonad. Onro kufta biposhand, baroi khunravi az hamai uzvho, varami buni dandon va mushakhoi halq davo meshavad. Zoki safedro kufta, bo asal khamir sokhta, fatilaro ba on olonda, dar gush guzorand, zakhmi daruni gushro shifo mebakhshad, daruni gushro az rimu chirk toza mekunad, dar maqad, ki bavosir doshta boshad, bardorand, foida mebakhshad. Kamtarero az zoki safed dar obi boron yo obi muqattar (distilyatsiyavi) hal karda, dar chashm chakonand, chashmro pok va guli onro raf mekunad.
