Gusukura ibikoresho by'ikirahure byahoze ari akazi ka buri munsi muri laboratwari. Ku bisigazwa bitandukanye nyuma y'ikizamini, intambwe zo gusukura, uburyo bwo gusukura, n'ingano y'amavuta yo kwisiga nabyo biratandukanye, ibyo bigatuma abagerageza benshi bashya bumva bafite umutwe.

None se twakora iki kugira ngo twoze amacupa y'ibirahuri vuba bishoboka, tugamije kugenzura isuku?

Mbere ya byose, tugomba gusobanukirwa ubwoko bw'ibirahuri bisukurwa?

Ikimenyetso cy'icupa risukuye ni uko amazi afatanye n'urukuta rw'imbere rw'icupa ry'ikirahure adaterana ngo abe ibitonyanga by'amazi cyangwa ngo atemba mu mugezi, cyangwa ngo akore agahu k'amazi ku rukuta rw'imbere.

Upfuke hejuru y'igikoresho cy'ikirahure n'amazi meza. Niba amazi meza ashobora gukora agapfunyika kandi agafata ku buso bw'ikirahure neza, kandi ntagire aho anyura cyangwa ngo atemba, ubwo ubuso bw'igikoresho cy'ikirahure buba busukuye.

Icyo gihe hazabaho ibintu bibiri. Hari abantu bazajya basukura amacupa y'ibirahure yakoreshejwe kugeza bageze ku bipimo byo gusukura byavuzwe haruguru. Ariko, agomba gusukurwa inshuro nyinshi kandi bitewe n'urwego rw'umwanda. Muri iki gihe, ni ugupfusha ubusa cyane. Igihe n'ingufu by'uwagerageje.

Abandi bakoresha uburyo bworoshye bwo koza ibintu bigaragara ku macupa y'ibirahuri n'amasahani. Ntacyo bitwaye niba amacupa n'amasahani byujuje ibisabwa mu isuku. Muri iki gihe, amacupa n'amasahani amwe atakarabye ashobora guteza amakosa mu igerageza ritaha. Ndetse n'igerageza ritagenze neza.

Umwanditsi ukurikira aragaragaza muri make uburyo butandukanye bwo gusukura amacupa n'amasahani bujyanye n'amahame agenga isuku, kandi urwego rutwara igihe kinini kandi rusaba imbaraga nyinshi ruragaragara.

1. Uko woza ibikoresho bishya by'ibirahuri: amacupa n'amasahani bishya byaguzwe birimo alkali nyinshi, bityo bigomba kwinjizwa mu cyuma gishyushye mu gihe cy'amasaha menshi hanyuma bigashyirwa mu mazi y'isabune mu gihe kirenga iminota 20. Nyuma yo gukaraba neza, koresha amazi asanzwe. Oza isabune kugeza igihe nta furo rihari, hanyuma woze inshuro 3-5, hanyuma woze inshuro 3-5 n'amazi yaciwe.

2. Uko woza amacupa n'amasahani byakoreshejwe mu kirahure:

(1) Imiyoboro yo gupimisha, amasahani ya petri, amacupa, amacupa yo kunyweramo, nibindi bishobora gusukurwa n'uburoso bw'icupa hakoreshejwe isabune (ifu yo kumesa cyangwa ifu yo gukuraho umwanda, nibindi), hanyuma bigasukurwa n'amazi ya robine. Ariko, ifu yo kumesa cyangwa ifu yo gukuraho umwanda ikunze kuba ku rukuta mu gihe cyo kuyikoresha. Hari utuntu duto duto tuyihambiraho, kandi akenshi yozwa n'amazi inshuro zirenga 10, hanyuma ikazumuka burundu.

(2) Amasahani ya petri afite ibintu bikomeye agomba gukurwaho mbere yo gukaraba. Amasahani arimo bagiteri agomba kwinjizwa mu muyoboro wica udukoko mu gihe cy'amasaha 24 cyangwa gutekwa mu gihe cy'amasaha 0.5 mbere yo gukaraba, hanyuma akagezwa n'amazi ya robine hanyuma akanyuzwa n'amazi yabugenewe. Kumisha bikorwa inshuro zirenze eshatu.

(3) Kugira ngo usukure icupa ry'amazi menshi, banza uryoge n'amazi ya robine inshuro nyinshi. Amazi amaze gusukwa, nta bitonyanga by'amazi biba biri ku rukuta rw'imbere. Ushobora kuryogesha n'amazi meza inshuro eshatu hanyuma ukabishyira ku ruhande. Bitabaye ibyo, bigomba kozwa n'amavuta ya aside chromic. Hanyuma oza icupa ry'amazi meza n'agasanduku k'amazi, uzunguze hanyuma woge gatatu n'amazi meza nyuma yo gukaraba.

Umwanditsi mukuru wavuzwe haruguru yashyize ahagaragara andi macupa n'amasahani asanzwe cyangwa yoroshye gusukura, kandi kuyasukura nabyo bifata igihe kinini n'ingufu nyinshi.

None se laboratwari nini zikemura gute iki kibazo gikomeye? Cyangwa zigahitamo gukoresha isuku y'intoki itwara umwanya munini kandi isaba akazi kenshi? Birumvikana ko atari byo! Ubu laboratwari nyinshi zitangiye gukoreshaimashini imesa ibikoresho by'ikirahure yikora, n'igihe cyaimashini yoza ibikoresho by'ikirahure muri laboratwariaho gukora isuku n'intoki byaratangiye.

None se ni ibihe bice by'iyi gahundaimashini imesa ibikoresho by'ikirahure yikorabishobora gusimbura isuku y'intoki?

1. Urwego rwo hejuru rw’ikoranabuhanga ryikora ku buryo bwuzuye. Bifata intambwe ebyiri gusa kugira ngo woze amacupa n’amasahani: Shyira amacupa n’amasahani mu kanda rimwe kugira ngo utangire gahunda yo gusukura (kandi irimo porogaramu 35 zisanzwe na porogaramu zihariye zishobora guhindurwa n’intoki kugira ngo zihuze n’ibyo abakiriya benshi bo muri laboratwari bakeneye). Ikoranabuhanga ribohora amaboko y’abagerageza.

2. Isuku ikora neza cyane (Imashini yo kumesa muri laboratwariImirimo yo gukora mu buryo bwa e-batch, isuku isubirwamo), umuvuduko muto wo gusenya amacupa (guhindura umuvuduko w'amazi, ubushyuhe bw'imbere, nibindi), uburyo bwinshi bwo gukora (guhuza ingano n'imiterere y'imiyoboro yo gupima, amasahani ya Petri, amacupa y'ingano, amacupa y'indobanure, silindiri zarangije, nibindi)

3. Umutekano mwinshi n'ubwirinzi, umuyoboro w'amazi winjiriramo udashobora guturika washyizweho mbere, umuvuduko n'ubushyuhe birwanya, ntabwo byoroshye kubipima, hamwe na valve igenzura irinda gusohoka, igikoresho kizahita gifunga iyo valve ya solenoid inaniwe.

4. Ubwenge bwo hejuru. Amakuru y'ingenzi nka conductivity, TOC, ubwinshi bw'amavuta yo koza, n'ibindi ashobora gutangwa mu gihe nyacyo, ibyo bikaba byorohereza abakozi babishinzwe gukurikirana no kumenya neza aho isuku igeze no guhuza sisitemu kugira ngo icapwe kandi ibikwe, ibyo bikaba byorohereza gukurikirana nyuma.
