Alumina (A / B / N)Alumina icyiciro gikomeye cyo gukuramo inkingi / SPE inkingi

Alumina ni aside isanzwe ya lewis, Centre ya aluminium ibura electron ebyiri. Ifite polar adsorbent ikomeye, isa na silicone, Hariho ibikorwa bitatu byo hejuru bya acide, alkalinity no kutabogama; Alumina nayo igira ingaruka zidasanzwe kuriπelectrons ya hydrocarbone ya aromatic, Nibyiza kuruta silicone mubihe byinshi bya pH. Uburyo nyamukuru bwo kugumana ni aside ya lewis / ibikorwa fatizo, polarite no guhana ion.

Acide aluminaAcide ya lewis ya alumina-A (pH = 4.5) yarazamuwe, Ubu bwoko bwa adsorbent bufite uburyo bwiza bwo kubika ibintu byinshi bya electron. Byongeye kandi, iyo kwitegura hamwe nigisubizo cya acide, adsorbent ifite imiterere ya cationic idakomeye, ubuso burashobora kugumana ibintu bitagira aho bibogamiye kandi byashizwemo nabi (nka anone ya electroneutral cyangwa acide), Ntishobora gukomeza kwishyurwa neza. binorohereza kugumana ibikoresho bibi byishyurwa.

Shingiro aluminaUbuso bwa Alumina-B (pH = 10) butoneshwa kugumana ibyiza cyangwa hydrogène - ibikoresho bihujwe. Aluminium oxyde ivurwa n'umuti wa alkaline ifite imiterere ya anionic hamwe nibikorwa byo guhanahana amakuru. Mubyongeyeho, nubwo ubuso bufite ibiranga base ya lewis, burashobora kugumana icyitegererezo cya electron, nkibintu bitagira aho bibogamiye. Ubushobozi buri hasi cyane kuri alumina idafite aho ibogamiye na aside. Mubyongeyeho, imigozi ikomeye ya hydrogène irashobora kuboneka kuri alumina-b, bityo ingaruka za polar cationic sample nazo ziragaragara.

Alumina itabogamyeAlumina-N (pH = 7.5) nayo ni polar adsorbent ikomeye. Ukurikije imiterere ya pH ndende, alumina irahagaze neza kuruta iyitsinda ryimikorere idafunze. Ibice bya finer byemeza neza gukuramo neza, bityo uburiri buto bwa silindrike (50mg) nigicuruzwa gikunze gukoreshwa. Adsorbent ntaho ibogamiye mumashanyarazi kandi ikunda kugumana ibikoresho bya elegitoroniki bikungahaye nka amine nziza kandi ibinure. Muri icyo gihe, hari n'ubushobozi bwo kugumana ibice birimo amatsinda ya electronegative nka ogisijeni irimo ogisijeni, fosifori na sulfuru. Alumina-N irashobora gukoreshwa mugukuramo no gutandukanya ibintu bya polar cyangwa bidafite inkingi mumazi ashonga kandi adafite amazi.

Ibyiza byibicuruzwa:

Quality Ubwiza bwibicuruzwa burahamye, kubyara neza, umutwaro ugereranije gutandukana (RSD) <5%.

Gupakira birasukuye kandi ntahantu hatagaragara.

Rate Igipimo cyo gukira ni kinini, kandi igipimo cyo gukira cyo kongeramo icyitegererezo 10 ~ 100ppm nicyiza cyiza cya 95% ~ 105%.

Performance Igiciro cyibicuruzwa biri mubicuruzwa byiza kwisi.

Ings Ibinyabuzima ngengabihe bya sintetike biratandukanye.

Products Ibicuruzwa bisanzwe, ibimera.

Method Ubuyapani JPMHLW uburyo bwemewe: umuti wica udukoko mubiryo.

★ Uburyo bwa AOAC na EPA.

Ubwitange bufite ireme:

★ Turemeza ko buri gicuruzwa cyujuje ibisabwa, tugakurikiza amahame akomeye yo kugenzura ubuziranenge kandi tugakora buri genzura.

. Menya neza ko buri gicuruzwa kidafite imbogamizi zuzuye, kandi igipimo cyo kugarura icyitegererezo kiruta icya leta, kigera ku rwego rwo hejuru rw’ibicuruzwa bimwe.

Kwiyemeza serivisi:

★ Dutanga inkunga ya tekiniki yumwuga kubuntu.
