Fig. 8From: Mineralogical and physico-chemical properties of halloysite-bearing slip surface material from a landslide during the 2018 Eastern Iburi earthquake, HokkaidoResults of electrophoretic analysis. (a) Zeta potentials with respect to pH. Results for reference halloysite and allophane samples are included for comparison. (b) Zeta potentials with respect to pH at different solute concentrations. Error bars denote the range of three repeated measurementsBack to article page
