Inzira igenda itanga zinc sulfate heptahydate nuburyo bwa acide sulfuric

Zinc sulfate Hepyabyte nayo yitwa Zinc Vitriol na Alum Vitriol. Misa yacyo ya molekori ni 287.56. Isura yayo ni uguceka kwera cyangwa ifu. Ni iy'amabuye y'agaciro ya orthorhombic kandi ubucucike bwarwo ni 1.97. Buhoro buhoro burira umwuka wumye. Uburyo nyamukuru bwo gutanga umusaruro burimo uburyo bwa acide sulfuric nuburyo bwa smithsonite.
Uburyo bwa acide sulfuric bukoreshwa mugukora zinc sulfate hepthitydrate, ikoresha aside sulfuric ikubiyemo ibikoresho bitandukanye birimo zinc cyangwa ibikomoka kuri zinc ifu yibicuruzwa bya zinc, ibikoresho bisigaye bivuye mu nganda zitunganya ibyuma ndetse non- Inganda za Ferrorugy, na zinc slag na zinc mines, nibindi
Ibikoresho birimo zinc byajanjaguwe numupira wumupira kandi bishonga hamwe na 18% kuri aside 25%. Iseswa rikorwa mu buryo bwa realtle yahujwe n'ibikoresho birwanya abode, nk'ikijyanwa, kandi gifite ibikoresho. Formactulantu reaction ni izi zikurikira:
Zn + h2so4 → znso4 + h2 ↑ zno + h2so4 → znso4 + h2o
Imyitwarire irashize kandi ubushyuhe buzamuka hejuru ya 80 ° C. Niba ibikoresho birimo umubare munini wa zinc, hazakorwa hydrogène nini. Kubwibyo, reaction igomba kuba ifite ibikoresho bikomeye byumunaniza. Kugirango wihutishe igipimo cyimyitwarire mugice cyanyuma cyimyitwarire, ibikoresho bya zinc-bikubiyemo bikubiyemo. Agaciro PH kurangiza reaction igenzurwa ahagana 5.1, kandi gusinzira birasobanuwe kandi byungurujwe. Ibirimo zinc muburyo bwa spoter bugomba kuba munsi ya 5%. Usibye zinc sulfate, filtrate ikubiyemo na sulfate ijyanye numwanda wicyuma mubikoresho fatizo. Gukuraho umwanda birashobora gukorwa mu ntambwe ebyiri. Ubwa mbere, umuringa, Nickel, nibindi biravanwaho, hanyuma icyuma kivanwaho. Imyambarire irashyuha kuri 80 ° C mukiruhuko, ifu ya zinc yongeyeho, kandi imvange irashirwaho cyane amasaha 4 kugeza kuri 6. Kubera ko zinc ifite ubushobozi bwo kugabanya umutekano ugereranije n'umuringa, Nickel, na Cadmium, ibyo byuma birashobora kwimurwa bivuye ku gisubizo. Formactulantu reaction ni izi zikurikira:
Zn + Cuso4 → Znu4 + Cuzn + Niso4 → znso4 + nizn + cdso4 → znso4 + cd
Igisubizo cyasimbuye kirusheho igitutu cyo gukuraho icyuma cyiza. Imyambarire yoherejwe mu isahani ya okiside, aherekeje kuri 80 ° C, na sodium hypochlorite, podium hymanium permanium, dioxyde de mangase, ibibi byongewe kuri oxidize mubyuma byinshi. Nyuma yama okidation, umubare ukwiye wa lime wongeyeho. amata kugirango aciremo hydroxide yamazi maremare hanyuma akayungurura. Mugihe ukoresheje ifu ya varije, ubike igisubizo nyuma yimvura kugirango urimbure ifu isigaye. Iyo ukoresheje potasiyumu permaganate, zinc oxide irashobora kongerwaho kugirango uhindure PH agaciro ka PH ka 5.1 kubera imvura yo ku buntu. Imyambarire yibanda ku guhumeka, gukonjeshwa munsi ya 25 ° C, na zinc sulfate Hepyaydrate Znso4 · 7h2o ari kworoha kandi yumye.
