... in and on the fouled membrane was determined. Fouling of the membrane as measured by flux reduction was usually accompanied by a positive change in zeta potential and iso-electric point (IEP) of the membrane. Severity of fouling seems to correlate with the presence of some pores of size larger tha ...

... 3-(2-aminoethylamino)propyl]trimethoxysilane. The changes on electrokinetic properties of modified sepiolite particles were studied by measuring the zeta potential of particle as a function of metal concentration and equilibrium pH of solution. It was found that the zeta potential of the cla ...

Limiting flux in skimmed milk ultrafiltration: impact of electrostatic repulsion due to casein micelles
... strength, chemical nature of added salts). The evolutions were explained taking into account the physicochemical characteristics (size distribution, zeta potential) of the casein micelles, that is the main components of the fouling layer formed at the membrane surface. It was shown that in the pH

... 3 and then, the adsorption of Cu(II) ion onto sepiolite from aqueous solutions as a function of pH, ionic strength and temperature. We found that (1) zeta potential of sepiolite suspensions increased with increasing ionic strength, (2) zeta potential values of sepiolite suspensions in different valenc ...
