TA - CHOSANTHULA CHA ALKALINI YONSE MU M'MADZI A NYANJA

Kuchuluka kwa mchere m'madzi ndi chinthu chofunikira kwambiri pa ntchito zambiri zasayansi kuphatikizapo kufufuza za acidization ya nyanja ndi carbonate chemistry, kuyang'anira njira za biogeochemical, ulimi wa nsomba m'madzi/ulimi wa nsomba komanso kusanthula madzi m'mabowo.

MFUNDO YOGWIRITSA NTCHITO

Kuchuluka kwa madzi a m'nyanja kumachepetsedwa ndi asidi poikamo kuchuluka kokhazikika kwa hydrochloric acid (HCl).
Pambuyo pa acidization, CO₂ yomwe imapangidwa mu chitsanzocho imachotsedwa pogwiritsa ntchito membrane based degassing unit zomwe zimapangitsa kuti pakhale open-cell titration. Kuzindikira pH kotsatira kumachitika pogwiritsa ntchito indicator dye (Bromocresol green) ndi VIS absorption spectrometry.
Pamodzi ndi mchere ndi kutentha, pH yomwe imachokera imagwiritsidwa ntchito mwachindunji powerengera kuchuluka kwa alkalinity.

MAWONEKEDWE

• Kuzungulira kwa miyeso kosakwana mphindi 10
• Kuzindikira pH yolimba pogwiritsa ntchito ma absorption spectrometry
• Kugawa kwa mfundo imodzi
• Kugwiritsa ntchito zitsanzo zochepa (<50 ml)
• Kugwiritsa ntchito mankhwala ochepa (100 μL)
• Makatiriji a reagent a "Plug and Play" omwe ndi osavuta kugwiritsa ntchito
• Kuchepetsa zotsatira za biofouling chifukwa cha acidization ya chitsanzo
• Kukhazikitsa kodziyimira pawokha kwa nthawi yayitali

ZOSANKHA

• Kuphatikiza mu machitidwe oyesera okha pa VOS
• Zosefera zodutsa madzi kuti madzi azikhala ndi dothi lochuluka / madzi odzaza ndi matope
