I-TA – ISIHLAZIYI SOKUTHOLA UBUNZIMA OBUPHELELE EMANZINI OLWANDLE

I-alkalinity ephelele iyipharamitha ebalulekile yesamba emikhakheni eminingi yesayensi yokusetshenziswa okuhlanganisa ucwaningo lwe-ocean acidification kanye ne-carbonate chemistry, ukuqapha izinqubo ze-biogeochemical, ukufuywa kwezinhlanzi emanzini kanye nokuhlaziywa kwamanzi emigodini.

ISIMISO SOKUSEBENZA

Inani elichaziwe lamanzi olwandle lenziwa libe yi-asidi ngokujova inani elinqunyiwe le-hydrochloric acid (HCl).
Ngemva kokwakheka kwe-acid, i-CO₂ ekhiqizwe kusampula isuswa ngokusebenzisa iyunithi yokukhipha igesi esekelwe ku-membrane okuholela kulokho okubizwa ngokuthi i-open-cell titration. Ukunqunywa kwe-pH okulandelayo kwenziwa ngokusebenzisa udayi wenkomba (i-Bromocresol green) kanye ne-VIS absorption spectrometry.
Kanye nosawoti kanye nokushisa, i-pH ephumayo isetshenziswa ngqo ekubaleni i-alkalinity iyonke.

IZICI

• Imijikelezo yokulinganisa engaphansi kwemizuzu eyi-10
• Ukunqunywa kwe-pH eqinile kusetshenziswa i-absorption spectrometry
• I-titration yephuzu elilodwa
• Ukusetshenziswa kwesampula okuphansi (<50 ml)
• Ukusetshenziswa kwe-reagent okuphansi (100 μL)
• Ama-cartridge e-reagent e-“Plug and Play” asebenziseka kalula
• Imiphumela ye-biofouling encishisiwe ngenxa yokwakheka kwe-acid kwesampula
• Ukufakwa okuzenzakalelayo kwesikhathi eside

IZINKETHO

• Ukuhlanganiswa kwezinhlelo zokulinganisa ezenzakalelayo ku-VOS
• Izihlungi zokugeleza kwamanzi ukuze kube nokugcwala okukhulu kwamanzi/agcwele inhlabathi
