Phenolphthalein isampula - element control

Kuyinto imfihlo ukuthi ngemuva kokusebenzisa amathuluzi yezokwelapha kanye nemikhiqizo badinga aphathwe ngokucophelela ukususa zonke izinhlobo zokungcola. Kuze kube yimanje, izindlela ezahlukene ezisetshenziswa. Ngemva ukwelashwa nge izihlanzi ngokuhambisana Izincomo methodical MH 28-6 / 13 sangomhla 08.06.1982 ka phenolphthalein isampula kumele ngempela abulawe.

ukwabela amasampula

Ukuze nokuhlola izinga yokwelashwa (ukuwasha) ebusweni iyiphi izihlanzi ithuluzi nezinye izinto kukhona izixazululo ukulungele ezahlukene. Phenolphthalein isampula ingenye izinyathelo kokuhlola khona amanani bokungasetshenziswa insipho, okungukuthi kuphela - izingxenye zawo ane-alikhali. Ukuze ukusetshenziswa kwalesi sitatimende, isixazululo we ketshezi. Ngokusho imihlahlandlela, kubalulekile ukwenza isixazululo 1% phenolphthalein. Ngokushesha ngemva kokuqala ekuwulungiseleleni kokuhlaziywa kwamathenda izinga ukucutshungulwa amathuluzi.

ukuhlolwa Ukuqhuba Phenolphthalein

It wenziwa izigaba eziningana. Endaweni yokuqala ithuluzi isicelo 2-3 amathonsi solution phenolphthalein. Kumelwe uthole ukuxhumana izingxenye ezinyakazayo bese endaweni lapho surface isilonda. Lokhu kungenxa ingozi lokuxhumana ayingozi futhi izinto eziphilayo ukusuka umthamo wegazi lesiguli.

Ngo isinyathelo esilandelayo uchwepheshe ihlola degree of isixazululo staining. Phenolphthalein isampula kubonisa lokuhlala ezahlukene alikhali. Ukubukeka color pink kubonisa khona surfactants ezimbi wageza. Ukuba khona isampula sinombala kubonisa khona nokugqwala chlorine-aqukethe oxidizing ejenti. Kwezinye izimo, le staining kuyinto pink-purple shades. Isebenza kuhle nxa ushintsho umbala isampula ziphathwe lonke batch amathuluzi siqondiswe ziwashwa kaningi ngamanzi agobhozayo. Babe iphathwa ngamanzi distilled.

Ngemva ukugeza amathuluzi ezibekwe iziqukathi ekhethekile necebo yokuhlanza. Bona achithwa presterilizing kabusha ukucubungula. Ngokukhethekile ikhokhelwa izinga yokuhlanza catheters kanye neminye imikhiqizo eziyize. Ngenxa yalesi isampula phenolphthalein labetibambile ngaphakathi ithuluzi ngokwethula ikhambi usebenzisa pipette noma isipetu. I reagent kufanele ahlale ngaphakathi umkhiqizo 30-60 imizuzwana. Khona-ke is batheleka izicubu futhi kuqhathaniswa LED.

Imigomo isampuli

Ngokuhambisana nemithetho yamanje ukubeka Phenolphthalein isampula Kwenziwa amayunithi (1% zomculo kanyekanye kusetshenzwe, kodwa hhayi ngaphansi kuka amayunithi ezintathu - ngaphambili ngaphambi kulayishwa ku inzalo); inzalo eyodwa (1% kubo bonke amagama emikhiqizo ukuthi selwenziwe ukuze shift). Imiphumela inqubo ukuqapha ezilotshwe ifomu №366 / y.

Control ochwepheshe magciwane nezenhlanzeko-epidemiological iziteshi okuhlanza inzalo zezempilo nsuku ngekwata. Lapho eliphansi ukucutshungulwa zonke izinsimbi kuhlinzwa namadivayisi yezokwelapha mhlawumbe itheleleke amanxeba ngesikhathi imisebenzi, ukuthuthukiswa kwesibindi nengculaza.
