Bipolar electrodialysis (BPED)

Bipolar electroosmosis yog ib qho kev siv hluav taws xob tshiab uas txhawb nqa cov dej ntws hauv cov xov xwm ntxeem tau los ntawm kev siv hluav taws xob ntawm electrodes los tsim hluav taws xob. Cov thev naus laus zis no tau siv dav hauv cov roj teeb rov ua dua tshiab, biomedical engineering, txhim kho cov roj rov qab thiab lwm yam kev lag luam, thiab tau txais txiaj ntsig rau nws cov kev ua haujlwm siab, txuag hluav taws xob, kev tswj hwm thiab lwm yam zoo.

Cov qauv ntawm Ion Exchange Membrane

Ion txauv membrane muaj cov qauv tshwj xeeb rau kev xaiv permeation ntawm anions thiab cations.

Cov qauv ntawm Bipolar Membrane

Txoj Cai Ua Haujlwm

- Kev sib cais ntawm cov dej rau hauv H + thiab OH- : H2O → H++OH-

- Hydrolysis voltage: 1.0 ~ 1.3V (tus nqi theoretical: 0.83V)

- High water decomposition efficiency>0.98

- Zoo heev durability

1.A bipolar membrane hais txog ib daim nyias nyias uas muaj kev sib xyaw ua ke ntawm ①an anion exchange layer, ②a cation exchange layer, thiab ③an intermediate catalytic layer.

2.Tom qab ib qho hluav taws xob siv thoob plaws hauv daim nyias nyias, dej hauv daim nyias nyias decomposes rau hauv acid (H +) thiab alkali (OH-).
