Product description
- Commercial colloidal quartz (Si02, trademark Min-U-Sil), fractionated to an equivalent particle radius of 0.3-0.5 µm, shows an electrophoretic mobility of -0.045 mm2 / (V * s) in a solution of 1.00 * 10-2 mol / l NaCl at 25.0 °C (pH 8). Calculate the DEL thickness and zeta potential. Find the necessary characteristics of the NaCl solution from the reference empirical equations:
where
C is in mol/l, η is in cps.
