| Description
| - The zeta potentials of kaolin dilute and concentrated suspensions were monitored using the techniques of electrophoresis and electroacoustics, respectively. The effect of addition of salt (KCl), a polymer material (Triton X-100), and an anionic surfactant (sodium dodecyl sulphate, SDS) on the suspension properties was investigated by electrophoresis. Electroacoustics was employed for the measurement of zeta potentials for the highest possible kaolin content in suspension and the effect of dilution. The effect of aging of a freshly prepared sample and kaolin isoelectric point was also studied. Using both techniques it was noted that there was no isoelectric point, just a maximum value in the magnitude of the kaolin suspension zeta potential. These maxima were observed also in the presence of Triton X-100 and SDS. An increase of the concentration of KCl and SDS in suspension shifted the maxima towards more acidic values, while in the presence of Triton X-100 the position of the zeta potential maxima rem

- Zeta potenciál zředěných a koncentrovaných kaolinových disperzí byl pozorován metodou elektroforézy a elektroakusticky. Vliv přídavku soli (KCl), a polymerního materiálu (Triton X-100) a anionického tenzidu (Sodium dodecylsulfátu, SDS) na vlastnosti suspenze byl studován elektroforetickými metodami. Elektroakustické metody byly použity pro měření zeta potenciálu pro nejvyšší možné koncentrace kaolinu v suspenzi a byl pozorován také vliv zřeďování. Vliv stárnutí čerstvě připravených vzorků a izoelektrický bod kaolinu byly také studovány. Použitím obou technik bylo zjištěno, že pro tento typ disperzí nebyl detegován izoelektrický bod, jenom maximum v hodnotě zeta potenciálu pro suspenzi kaolinu. Tato maxima byla pozorována také po přídavku Triton X-100 a SDS. Se zvyšující se koncentrací KCl a SDS ve vodní suspenzi se tato maxima posouvají více do kyselé oblasti, přičemž v přítomnosti Triton X-100 se poloha maxima zeta potenciálu nemění a zůstává konstantní. Elektroakustickými technikami bylo zjištěno, ž (cs)
