Dynamics of colloid transport-deposition in water-bearing media under different environments of sodium absorption ratios

Column experiment was conducted to elucidate dynamics of colloid transport-deposition in the coastal porous media of Tianjin with different sodium absorption ratios(SAR).Kinetics curves of colloid deposition were measured,and deposition ratio and deposition rate constants of colloid were calculated.Moreover,the mechanism of colloid transport-deposition was discussed.Results show that the breakthrough curve of colloid had the critical pore volumes(CPV)compared with the tracer ion,and the transpor...
