Imitha yoxinaniso ye-ion sisixhobo esiqhelekileyo sohlalutyo se-electrochemical elebhu esetyenziselwa ukulinganisa i-ion concentration kwisisombululo.I-electrodes ifakwe kwisisombululo ukuba ilinganiswe kunye ukwenza inkqubo ye-electrochemical yokulinganisa.
Imitha ye-ion, eyaziwa ngokuba imitha yomsebenzi we-ion, umsebenzi we-ion ubhekiselele ekugxininiseni okusebenzayo kweeyoni ezithatha inxaxheba kwi-electrochemical reaction kwisisombululo se-electrolyte.Umsebenzi wemitha yoxinaniso ye-ion: uhlobo lokuchukumisa-isikrini esikhulu se-LCD ukubonisa, ujongano olupheleleyo lwesiNgesi.Ngokulungelelaniswa kwamanqaku amaninzi (ukuya kumanqaku angama-5) kuvumela abasebenzisi ukuba benze imisebenzi yabo eqhelekileyo.
I-ion analyzer inokubona ngokulula kwaye ngokukhawuleza ubungakananiFluoride ion, nitrate radicals, pH, ubulukhuni bamanzi (Ca 2 +, Mg 2 + ions), F-, Cl-, NO3-, NH4+, K+, Na+ ionsemanzini, kunye nogxininiso oluchanekileyo lwezinto ezahlukeneyo ezingcolisayo.
Uhlalutyo lwe-Ion lubhekiselele ekukhetheni iindlela ezahlukeneyo zokuhlalutya kunye nokuvavanya ngokweempawu ezahlukeneyo zesampulu ukufumana uhlobo kunye nomxholo wezinto okanye i-ion kwisampulu, ukuqonda uhlalutyo lohlobo kunye nomxholo wezinto okanye ion kwisampulu, kunye nokuhlangabezana neemfuno zabathengi kuhlalutyo lwe-ion element.
WukwenzaPrinciple
Umhlalutyi we-ion ikakhulu usebenzisa indlela yokulinganisa i-ion ekhethiweyo ye-electrode ukufezekisa ukufumanisa ngokuchanekileyo.I-Electrodes kwisixhobo: i-fluorine, i-chlorine, i-sodium, i-nitrate, i-ammonia, i-potassium, i-calcium, kunye ne-reference electrode.I-electrode nganye ine-membrane ekhethiweyo ye-ion, ephendula kunye neeoni ezihambelanayo kwisampulu eziza kuvavanywa.I-membrane yi-ion exchanger, kunye nokukwazi phakathi kolwelo, isampuli kunye ne-membrane inokubonwa ngokusabela ngentlawulo ye-ion ukutshintsha i-membrane enokwenzeka..Umahluko phakathi kwezinto ezimbini ezinokuthi zibonwe kumacala omabini e-membrane ziya kuvelisa i-current.Isampulu, i-electrode yereferensi, kunye nolwelo lwe-electrode yesalathiso lwenza icala elinye le "loop", kunye nenwebu, ulwelo lwe-electrode yangaphakathi, kunye ne-electrode yangaphakathi kwelinye icala.
Umahluko kugxininiso lwe-ionic phakathi kwesisombululo se-electrode yangaphakathi kunye nesampulu ivelisa amandla ombane we-electrochemical kwi-membrane ye-electrode esebenzayo, ekhokelelwa kwi-amplifier nge-electrode yangaphakathi eqhuba kakhulu, kwaye i-electrode yereferensi ikwakhokelela kwindawo ye-electrode. isandisi-lizwi.I-curve yokulinganisa ifunyenwe ngokulinganisa isisombululo esichanekileyo esichanekileyo sokugxilwa kwe-ion eyaziwayo ukufumanisa i-ion concentration kwisampuli.
Ukufuduka kwe-Ion kwenzeka ngaphakathi kwinqanaba elimanzi le-ion-selective electrode matrix xa ii-ion ezilinganisiweyo kwisisombululo zidibanisa i-electrodes.Utshintsho kwintlawulo yee-ion ezifudukayo zinamandla, okutshintsha amandla phakathi kwendawo ye-membrane, okwenza umehluko okhoyo phakathi kwe-electrode yokulinganisa kunye ne-electrode reference.
Aisicelo
Ukubeka iliso kwimilinganiselo ye-ammonia, i-nitrate, njl njl kumanzi angaphezulu, amanzi aphantsi komhlaba, iinkqubo zoshishino kunye nokucocwa kogutyulo.
Iimitha yoxinaniso ye-fluoride ionyenzelwe ukulinganisa iumxholo we-fluoride ionkwisisombululo esinamanzi, ngakumbi ekujongeni umgangatho wamanzi acocekileyo kwizityalo zamandla (ezifana nomphunga, i-condensate, amanzi okutya kwibhoyila, njl. njl.) Iikhemikhali, i-microelectronics kunye namanye amasebe, zimisela ukugxila (okanye umsebenzi) wei-fluoride ionskumanzi endalo, imisele yemizi-mveliso kunye namanye amanzi.
Mulungiso
1. Ukusombulula njani xa idetector isilela
Kukho izizathu ezi-4 zokuba kutheni i-detector isilele:
①Iplagi yesixhobo ikhululekile kunye nesitulo sebhodi yomama;
②Isixhobo ngokwaso saphukile;
③ Isikrufu sokulungisa kumbindi wevalve kunye neshafti ejikelezayo yemoto ayibotshwanga endaweni;
④ I-spool ngokwayo iqine kakhulu ukuba ingajikeleza.Ulandelelwano lohlolo ③-①-④-②.
2. Izizathu kunye neendlela zonyango lwesampulu engalunganga yokufunxa
Zine izizathu ezingundoqo zomnqweno ongemhle wesampulu, ezijongwa ngendlela "elula ukuya kwentsonkothileyo":
①Jonga ukuba ngaba imibhobho yokudibanisa yojongano ngalunye lombhobho (kuquka imibhobho edibanisayo phakathi kwee-electrode, phakathi kwee-electrode neevalvu, naphakathi kwe-electrode nemibhobho yempompo) iyavuza.Lo mcimbi ubonakaliswa kungabikho sampuli yokufunxa;
② Khangela ukuba ityhubhu yempompo ibambekile okanye idinwe kakhulu, kwaye ityhubhu entsha yepompo kufuneka itshintshwe ngeli xesha.Isiganeko kukuba i-tube yepompo yenza isandi esingaqhelekanga;
③ Kukho imvula yeprotheyini kumbhobho, ngakumbi kumalungu.Lo mcimbi ubonakaliswa njengokumisa okungazinzanga kwenkqubo yesantya sokuhamba kwamanzi, nokuba ityhubhu yempompo ithathelwe indawo entsha.Isisombululo kukususa amajoyina kwaye uhlambulule ngamanzi;
④ Kukho ingxaki ngevalve ngokwayo, ngoko yijonge ngononophelo
