Ko e founga ke Fakaleleiʻi ʻaki Electrode laa Fouling

Ko e Electrode fouling ko ha palopalema lahi ia ʻi he ngaahi founga electrochemical lahi pea ʻi electrochemical sensors. ʻE lava ke uesia ʻe Electrode fouling ʻa e ngaue mo e ivi feʻunga ʻo ha electrochemical toʻotoʻo. Ko e Ultrasonication ko ha founga lelei ia ke fakaʻehiʻehi mo toʻo electrode fouling.

ʻOku fakasiʻisiʻi ʻe Electrode fouling ʻa e fetuʻutaki fakatuʻasino ʻa e electrolyte mo e electrode ki electron feʻaveʻaki pea ko ia ʻoku ne fakasiʻisiʻi ʻa e vave ʻo e tali electrochemical. ʻOku faʻa adheres ʻa e fakafofonga fouling ki ha faʻunga pau ʻi he tafaʻaki electrode ko e ola ia ʻo hydrophilic, hydrophobic, pe electrostatic ngaahi fengaueʻaki ʻi he vahaʻa ʻo e fakafofonga fouling mo e electrode.

ʻOku kau ʻi he ngaahi founga Antifouling ʻa e liliu pe coating ʻaki ʻa e ngaahi naunau polymers pe kaponi, hange ko e kaponi nanotubes pe graphene, koeʻuhi ko honau feituʻu lahi, electro-catalytic, mo e fakafepaki fouling. Pe, meʻa nanoparticles lava ke ʻi ai ha ngaahi koloa antifouling fakataha mo electro ngaahi koloa catalytic mo e ʻuhila maʻolunga conductivity.

Ko e ultrasonic fakamisini ko ha founga ia ʻe taha antifouling.

ʻOku fakaʻaongaʻi ʻe ultrasonic hono ueʻi holo ʻo e antifouling ʻa e ngaahi peau lalahi mo malohi ʻi ha vai ke fakafaingofuaʻi pe fakaleleiʻi hono toʻo ʻo e kau fakafofonga fouling mei he tafaʻaki ki ʻolunga ʻi ha ultrasonically kuo fakamoʻui. Ko ultrasonic electrode fakamaʻa ko ha tekinolosia makehe ia ʻi heʻene malava ke toʻo fouling kau fakafofonga mei electrode tafaʻaki ki ʻolunga. ʻOku lava ʻe ultrasonic tekinolosia fakamaʻa ʻo hu ki loto mo fakamaʻa ha faʻahinga wetted electrode, kau ai ʻa e ngaahi luo kui, filo, mo e ngaahi takimamata ʻi he fukahi tahi.
Kuo hanga ʻe he ngaahi fie maʻu ke fakaleleiʻi electrode e maʻa ʻo tekeʻi ʻa e fakalakalaka ʻo ultrasonic tekinolosia ʻoku ne ueʻi holo. ʻI he ʻaho ni ʻoku malava pe ke ueʻi hake electrodes ʻi he tuʻo lahi ultrasonic pe ke ueʻi hake ʻa e vai ofi ki he electrode ki hono fakamaʻa ʻo e electrode.

ʻI he antifouling fakahangatonu ʻo e electrode, ʻoku ʻave ai ʻa e malohi ultrasonic ki he huhuʻa ofi ki he electrode. ʻOku hanga ʻe he adsorbs huhuʻa ko ʻeni ʻo ʻave ʻa e malohi ultrasonic mo ʻave ha konga siʻi ʻo e malohi ko ʻeni ki he fukahi electrode, ʻa ia ʻoku toʻo ai ʻe he ultrasonic cavitation ʻa fouling. Ko hono fakalūkufuá, ko e founga ʻoku ʻikai fakahangatonu ko ʻení ko e "laine ʻo e ʻao" ʻi natula; ʻa ia, kuo pau ke ʻi ai ha faingamalie fakahangatonu ki he meʻa ʻoku ʻuli ke ola lelei.
