Yuav Siv Aluminium Hydroxide Gel li cas
Feb 16, 2022
Alumina gel feem ntau yog hais txog aqueous suspension ntawm aluminium hydroxide. Cov gel yog npaj los ntawm reacting txhuas chloride nrog ammonia dej, ntxuav tawm ammonium ions nrog ib tug loj npaum li cas ntawm distilled dej, thiab ces autoclaving. Yuav siv tau rau kev npaj tshuaj tiv thaiv. Yog li cia peb saib seb yuav siv li cas.
Aluminium hydroxide gel yog cov kua nplaum nplaum dawb; cov txheej nyias nyias yog translucent, thiab cov dej me me tuaj yeem raug tshem tawm tom qab sawv; nws muaj cov tshuaj tiv thaiv me ntsis thaum nws ua tau raws li daim ntawv liab lossis xiav litmus, thiab nws tsis tau raws li cov tshuaj phenolphthalein qhia. Liab. Cov khoom no yog ib qho kev ncua-hom gel kua tsim los ntawm dispersing me me colloidal hais ntawm txhuas hydroxide nyob rau hauv dej. Cov ntsiab lus ntawm aluminium hydroxide yuav tsum yog 3.6 mus rau 4.4 feem pua (g / g) xam ntawm alumina.
Hais txog nws qhov kev tshuaj xyuas zoo, cov kua qaub ntau lawm, cov ntsiab lus chloride, cov ntsiab lus sulfate, cov ntsiab lus hlau hnyav, cov ntsiab lus ntawm arsenic ntsev thiab cov ntsiab lus aluminium hydroxide yuav tsum tau txiav txim siab raws li qhov yuav tsum tau ua ntawm "Pharmacopoeia", uas yog tag nrho raws li "Pharmacopoeia" .
Lus Ceeb Toom: Rau koj tus kheej kev nyab xeeb, ua ntej siv cov txhuas hydroxide gel reagent, thov ceev faj, xws li hnav cov tsho loj thiab hnab looj tes. Qhov ntsuas kub cia yog 2-8 degrees Celsius.
