文摘
- •
Gel layer had high filtration resistance but high measured porosity simultaneously.
- •
Filtration resistance of gel was independent of pH and ionic strength.
- •
Current knowledge cannot reasonably explain the high resistance of gel layer.
- •
Chemical potential change in gel layer filtration was revealed and described.
- •
A new mechanism was proposed to be responsible for high resistance of gel layer.
