Why zeta potential gets more negative values with increasing the concentration of monovalent salts from 1mM to 10mM?

For silica particles (size 1-5 um), with increasing the concentration of monovalent salts (NaF, NaCl, NaBr, NaI, etc.) from 1mM to 10 mM, more negative electrophoretic mobility(EM) and...

What is the best way for measuring contact angle of heavy metals (e.g. Pb, Cu, Zn) on the silica particles surface in the adsorption process?

I am going to investigate the surface free energy of silica particles in the presence of heavy metal ions according to vanOss–Chaudhry–Good (vOCG) theory. So that, I need the contact angle of...
