Labarai - Me Yasa Ake Bukatar Kula da Na'urar Nazarin Ion ta Intanet?

Mita mai auna yawan ion kayan aiki ne na nazarin lantarki na dakin gwaje-gwaje wanda ake amfani da shi don auna yawan ion a cikin maganin. Ana saka electrodes a cikin maganin don a auna tare don samar da tsarin lantarki don aunawa.

Mita ion, wanda kuma aka sani da mitar ayyukan ion, aikin ion yana nufin ingantaccen yawan ions da ke shiga cikin amsawar lantarki a cikin maganin electrolyte. Aikin mitar maida hankali na ion: babban allon LCD mai nau'in taɓawa, cikakken hanyar sadarwa ta aiki ta Ingilishi. Tare da daidaitawar maki da yawa (har zuwa maki 5) yana bawa masu amfani damar ƙirƙirar nasu saitin ayyuka na yau da kullun.

Mai nazarin ion zai iya gano shi cikin sauƙi da sauri cikin adadiions na fluoride, nitrate radicals, pH, taurin ruwa (Ca2+, Mg2+ ions), F-, Cl-, NO3-, NH4+, K+, Na+ ionsa cikin ruwa, da kuma daidaiton yawan gurɓatattun abubuwa daban-daban.

Binciken ion yana nufin zaɓar hanyoyin bincike daban-daban don nazari da gwaji bisa ga halaye daban-daban na samfurin don samun nau'in da abun ciki na abubuwan ko ions a cikin samfurin, don fahimtar nau'in da abun ciki na abubuwan ko ions a cikin samfurin, da kuma biyan buƙatun abokin ciniki don nazarin ion na abubuwa.

WorkingPrinciple

Mai nazarin ion galibi yana amfani da hanyar auna electrode na ion selective don cimma daidaiton ganowa. Electrodes akan kayan aikin: fluorine, chlorine, sodium, nitrate, ammonia, potassium, calcium, da electrodes na reference. Kowane electrode yana da membrane mai zaɓin ion, wanda ke amsawa da ions masu dacewa a cikin samfurin da za a gwada. Membrane ɗin musayar ion ne, kuma ana iya gano yuwuwar tsakanin ruwa, samfurin da membrane ta hanyar amsawa da cajin ion don canza yuwuwar membrane. . Bambanci tsakanin yuwuwar guda biyu da aka gano a ɓangarorin biyu na membrane zai samar da wutar lantarki. Samfurin, electrode na reference, da ruwa na electrode na reference suna samar da gefe ɗaya na "madauri", kuma membrane, ruwa na electrode na ciki, da electrode na ciki suna samar da ɗayan gefen.

Bambancin yawan ionic tsakanin maganin electrode na ciki da samfurin yana samar da wutar lantarki ta lantarki a fadin membrane na electrode mai aiki, wanda ke kaiwa ga amplifier ta hanyar electrode na ciki mai yawan aiki, kuma ana kai wutar lantarki ta hanyar amfani da na'urar aunawa zuwa wurin da amplifier ɗin yake. Ana samun lanƙwasa ta hanyar auna daidaitaccen bayani na daidaiton yawan ion da aka sani don gano yawan ion a cikin samfurin.

Shigowar ion yana faruwa ne a cikin layin ruwa na matrix na electrode na zaɓin ion lokacin da ions da aka auna a cikin maganin suka haɗu da electrodes. Canjin cajin ions masu ƙaura yana da yuwuwar, wanda ke canza yuwuwar tsakanin saman membrane, yana haifar da bambanci mai yuwuwa tsakanin electrode mai aunawa da electrode mai tunani.
