Product description
Monodisperse polystyrene latex (with a copolymer of methacrylic acid and the sodium salt of vinylphenylsulfonate) with a particle diameter of 610 nm was studied by microelectrophoresis in an aqueous medium of 1.00 mmol/dm3 of potassium chloride KCl. At 25 0С (and pH 7) the electrophoretic mobility was 4.05*10-8 m2/(s*V). Calculate the thickness of the DEL and the zeta potential, assuming εr = 78.35, η= 0.890 cP.
