Alumina arụ ọrụ maka ọgwụgwọ mmiri
Okwu Mmalite ngwaahịa
Ngwaahịa ahụ bụ ihe na-acha ọcha, ihe na-acha odo odo nke nwere ihe onwunwe nke na-adịghị egbu egbu, isi ísì, na-adịghị edozi na mmiri na ethanol. The urughuru size bụ edo, elu bụ ezigbo, n'ibu ike dị elu, ike nke mmiri absorption bụ ike na bọl na-adịghị kewaa mgbe absorbing mmiri.
The partical size nwere ike ịbụ 1-3mm, 2-4mm / 3-5mm ma ọ bụ ọbụna nta dị ka 0.5-1.0mm.It nwere ibu kọntaktị ebe na mmiri na kpọmkwem elu ebe elu karịa 300m² / g, o nwere nnukwu ibu nke quantity. microspores na nwere ike hụ na adsorption siri ike na oke defluorination na fluorinion na mmiri.
Alumina maka hydrogen peroxide nwere ọtụtụ ọwa capillary na nnukwu akụkụ elu, nke enwere ike iji mee ihe dị ka adsorbent, desiccant na catalyst. N'otu oge ahụ, a na-ekpebikwa ya dabere na polarity nke ihe adsorbed. Ọ nwere njikọ siri ike maka mmiri, oxides, acetic acid, alkali, wdg. arụ ọrụ alumina bụ ụdị micro-mmiri miri desiccant na ihe adsorbent maka adsorbing pola ụmụ irighiri ihe. .
N'okpuru ụfọdụ ọnọdụ ọrụ na mmeghari ọnọdụ, omimi ihicha ya dị elu dị ka ebe igirigi dị n'okpuru -40 ℃, ọ bụkwa ihe na-arụ ọrụ nke ọma maka ikpochapụ miri emi nke mmiri. Ọ na-ọtụtụ-eji gas na mmiri mmiri na-adọ ihicha nke petrochemical ụlọ ọrụ, ihicha nke textile ụlọ ọrụ, oxygen mmepụta ụlọ ọrụ na akpaka ngwá ikuku, mgbali siwing adsorption na ikuku nkewa ụlọ ọrụ, wdg N'ihi na elu net okpomọkụ nke monomolecular adsorption oyi akwa, ọ. dị nnọọ mma maka ngwaọrụ mmeghari okpomọkụ. Alumina maka hydrogen peroxide bụ ọcha sppherical porous ahụ na edo urughuru size, ezigbo elu, elu n'ibu ike na ike hygroscopicity. A na-eme ya nke alumina dị oke ọcha site na nkwadebe sayensị na mmecha catalytic. Enwere ike iji ya dị ka onye na-ewepụ fluoride maka mmiri fluoride dị elu, na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ebe dị elu. Mgbe uru pH na alkalinity nke mmiri raw dị ala, ikike iwepụ fluorine dị elu, karịa 3.0mg/g. Enwere ike iji ya mee ihe maka iwepụ fluorine, iwepụ arsenic, nsị mmiri mmiri na-ekpochapụ mmiri na deodorization nke mmiri ọṅụṅụ na ngwaọrụ mmepụta ihe.
