Yo ango ma ki tiyo kwede me nongo yamo ma ki lwongo ni oxygen ma tye i pii?
Kit me temo jami ma ki tiyo kwede i lobo wa tye iye: "Nwongo yamo ma odonyo i pii - yoo me Iodometric" (GB7489-1987), "Nwongo yamo ma odonyo i pii - yoo me Electrochemical probe" (HJ506-2009), ki rwom me American ASTM (D888-05). Gin aryo mukwongo ni obedo yoo ma ki tiyo kwede i lobo China, ki me aryo ni obedo yoo ma ki ngeyo ki US Environmental Protection Agency.
Yo me nongo yamo ma ki lwongo ni dissolved oxygen i pii - yoo me iodometric
Cik me yoo me iodometric me pimo yamo ma ki lwongo ni dissolved oxygen: Nongo yamo ma ki lwongo ni dissolved oxygen i pii pol kare ki tiimo kun kitiyo ki yoo me iodometric. Med manganese sulfate ki alkaline potassium iodide i pii me yubu manganese hydroxide precipitate. Pi kit ma manganese hydroxide ni pe rwate kwede, en oyot rwate ki yamo ma ki lwongo ni oxygen i pii me yubu manganese sulfate. Iyonge dakika 15, medo sulfuric acid ma ki keto i kom gin ma ki lwongo ni brown precipitate ni rwate ki potassium iodide ma ki medo i kom gin ma ki rubu ni, ki iodine mapol, ci yamo ma ki lwongo ni dissolved oxygen dwong, ki kala pa gin ma ki rubu ni bedo macol. Kwany wel pii ma ki kwanyo ki i pipette, tic ki jami ma ki lwongo ni starch ma calo lanyut, titrate ki standard solution, ki kwano wel oxygen ma tye i pii ni.
Kit me pimo iodine tye ki rwom ma lamal ki pi ber pi pimo i kabedo, ma weko kare me nongo ne tero kare malac. I pii ma lum dongo iye, tic ki jami ma ki lwongo ni photosynthesis medo wel oxygen ma ki gonyo, ma twero weko oxygen ma tye i pii ni oo i rwom ma malo. I kare ni, tek me nongo yamo ma ki keto i pii kun kitiyo ki yoo me iodine, ki adwogi me pimo ni pe tye kakare.
Yo me nongo yamo ma ki lwongo ni dissolved oxygen i pii - electrode polarography
Cik me electrode polarography me pimo yamo ma ki lwongo ni dissolved oxygen: teko ma rwate ki keto i kin electrode aryo ni, ki electrons gi mol ki i cathode me oo i anode, ma kelo diffusion current; I rwom me lyeto mo, rwom me nya pa yamo ni rwate ki dwong pa yamo ma ki lwongo ni dissolved oxygen; Ket rwom me rwate i kin rwom me yamo ma tye ka mol ki yamo ma tye ka mol; Gin ni loko rwom me ammeter me doko dwong pa yamo ma ki lwongo ni dissolved oxygen ki nyutu wel oxygen ma ki keto i cim.
Kit me electrode polarography me nongo yamo ma ki lwongo ni dissolved oxygen i pii tye ki yoo ma yot ki oyot, ki wel jami ma ki tiyo kwede ni tye piny, ma tye i yoo ma ki tiyo kwede i wilobo. Ento ka oxygen tye ka tic, cilo obi dongo i kom membrane ki electrode, ma obi yubu oxygen gradient ma obi dwoko piny rwom me tic. Ka gin ma ki lwongo ni semi permeable membrane ni obale, electrolyte ni twero balo oyot, ma twero kelo rweny pa kero pa battery, ki rweny ni obi nyute ma pi opore calo dwong pa oxygen ma ki keto i pii ni. Pi meno, mitte ni ki lok kare ki kare electrolyte ki semi permeable membrane.
Yo me nongo yamo ma ki lwongo ni dissolved oxygen i pii - yoo me fluorescence
Cik me yoo me fluorescence me pimo yamo ma ki lwongo ni dissolved oxygen: mac ma bulu ma ki loko ki keto i kom jami ma ryeny me yomo cwiny gi ki miyo mac makwar. Pi teko pa molecules me oxygen, kare ki teko pa lero makwar ma kelo miti tye ma rwate ki dwong pa molecules me oxygen. Nong ki tic ki mac ma kwa ma rwate ki mac ma bulu ma calo lanyut, pimo apoka poka ma tye i kin mac ma kwa ki mac ma nyutu, ki poro wel ma ki keto me kwano dwong pa molecules me oxygen. Iyonge tic mogo, ki kwanyo yamo ma ki lwongo ni dissolved oxygen.
Kit me LDO ma ki lwongo ni fluorescence me pimo yamo ma ki lwongo ni dissolved oxygen i pii obedo yoo ma yot ki oyot. Ka kiporo ki yoo aryo mukwongo ni, yoo me fluorescence LDO me pimo yamo ma ki lwongo ni dissolved oxygen i pii pe mito calibration, tye ki kare me gamo oyoto, adwogi me pimo ma rwate, pe mito mol, pe ki balo, dwoko piny kare me lwoko, ki gwoko ne manok.
