“…A number of interesting experimental data has also been gathered using the AFM observations for latex [21,24,26], colloid gold [81] or dendrimer suspensions [32]. One can also apply the electron microscopy to determine particle coverage [18] or the indirect methods like reflectometry [15,22,32,37], ellipsometry [82], radioisotopic labelling [83][84][85], or streaming potential [40,41,[86][87][88]. The latter method is especially sensitive and can be used for particles of arbitrary size ranging from ions, polyelectrolytes, proteins to large colloid particles of micrometer size range [89].…”

“…Particle adsorption onto solid surfaces is a very important process in a variety of fields such as filtration and flotation, paper making and textiles, functional materials, pharmaceutical and cosmetic industries [1][2][3][4][5][6][7]. For example, hydrophobic, conductive and antibacterial textiles could be fabricated by coating fibers with nanoparticles [8][9][10][11].…”

A more sensitive and accurate method for measuring very low concentration of cationic copolymer nanospheres is established by measuring the conductivity of cationic nanosphere dispersion. The effect of the nanosphere concentration on the conductivity was investigated during the adsorption process. The results indicate that the relationship between the concentration of nanospheres and bromide ions is coincidence with linear relation. At very low nanosphere concentrations, the conductivity increases with increasing the nanosphere concentration, exhibiting a linear relationship. However, the limiting molar conductivity of nanosphere decreases with increasing nanosphere concentration. The obtained adsorption data were fitted to the Langmuir adsorption isotherm. The SEM images show that the nanospheres form a uniform monolayer on cotton fiber surfaces. The saturated amount of the nanospheres on the cotton fibers is 63.49 mg/g.

The Effects of Surface Charging Properties on Colloid Transport in Porous Media

Transport properties of colloidal particles in a packed bed of collector beads are affected by hydrodynamic and colloidal interactions between particles as well as between the particle and the collector. The colloidal interaction depends on the surface charging of collectors and particles. While many researchers have studied on the colloid deposition and transport in porous media as a function of ionic strength, experimental investigations examining the effect of surface charge are scarce. To figure out the effect of surface charge on the colloid transport in porous media, we have performed colloid transport experiments in a packed bed of spherical beads. In the present experiment, we used sulfate latex with a constant negative charge and carboxylate latex having pH-dependent negative charge as colloidal particles. Zirconia beads with pH-dependent charge and an isoelectric point around pH 7 were adopted as collectors. Colloid transport experiments were carried out in 1 mM KCl as a function of pH and breakthrough curves of colloid were obtained. The experimental breakthrough curves were analyzed by a convection-dispersion equation including colloid deposition, where colloid filtration and dynamic blocking are considered. The results of experiments and analysis show that the maximum surface coverage of sulfate latex on the collector surface is constant against pH change. On the one hand, the maximum coverage of carboxyl latex decreases with increasing pH, indicating that the lateral particle-particle repulsion increased by high charge enhances blocking in later stage of deposition. The result suggests that electro-hydrodynamic interaction also affects the maximum coverage.
