Advancing the knowledge of solute transport in the presence of bound water in mixed porous media based on low-field nuclear magnetic resonance

Advancing the knowledge of solute transport in the presence of bound water in mixed porous media based on low-field nuclear magnetic resonance

•Bound water (BW) enhanced non-Fickian characteristics.•Immobile water fraction increased with increasing estimated bound water.•Solute exchange rate decreased with increasing bound water.•Moderately non-Fickian solute transport occurred in porous media with BW
