Most natural sediment particles have numerous pores and a complex surface texture which facilitates their adsorption of contaminants. Particle surface structure, therefore, is an important instrumental factor in the transport of contaminants, especially in water environments. This paper reports on the results of adsorption-desorption experiments to analyze polluted sediment surface pore tension characteristics performed on samples from the bottom of Guanting Reservoir. In our analysis, the Frenkel-Halsey-Hill (FHH) equation is applied to calculate the fractal dimensions of particles to quantify the surface roughness and pore tension characteristics. The results show that the surface fractal dimensions of sediment particle surfaces normally measure from 2.6 to 2.85. The volume of pores smaller than 10 nm changes significantly after being contaminated with pollutants and the fractal dimension decreases because the pores adsorb the contaminants. sediment pollution, pore distribution, fractal dimension, adsorption mechanics

“…The hysteresis loop formed from the adsorptiondesorption branch of Ca 8 Zr 2 is a typical H3 hysteresis loop, as proposed by International Union of Pure and Applied Chemistry (IUPAC). And thus, SGCS-made Ca 8 Zr 2 should be mesoporous sorbent with slitlike pore [60], also as observed in Fig. 7(a) above for the FSEM figure of Ca 8 Zr 2 .…”

“…Recently, Neimark (10 -13) has suggested the possibility of applying the thermodynamic method, until now used exclusively on the nitrogen adsorption data (14,17,18), for calculating the surface fractal dimension from mercury porosimetry experiments. In this method, the analogue of the Kiselev integral equation used for determining the area of the liquid-vapor interface from sorption experiments is the Rootare-Prenzlow equation (19),…”
