Adding acetic acid to specific kaolin induces reverse electroosmotic flow (EOF). The experimental results indicate that the pH of the kaolin after experimentation ranged from 3.78 to 10.48, which did not reach the point of zero charge (pHPZC) identified by previous studies as the critical factor causing the reverse EOF. This reverse EOF was attributed to the differential …

The surface zeta potential variation of the hard kaolin as a function of pH was almost the same as that of the soft kaolin. The IEP of the hard kaolin varied from 2.5 to 3.8. The SiO 2 (wt%) content of the several kaolins showed negative correlations with IEP, but Al 2 O 3 (wt%) content showed positive correlation with IEP.

Abstract. Kaolin has been widely used both in fundamental studies of soil behavior and in physical model tests. However, the properties of pure kaolin are somewhat atypical of natural clay soils. In the first part of this paper we compare the mechanical properties of sedimented kaolin to median trends established from tests on natural clays and argue that …

The initial pH of the synthetic test waters was on the alkaline side (≥8.2). The alkalinity of the test waters was as high as 180–205 mg/L. The pH and alkalinity were measured after coagulation-flocculation and a constant decrease was seen in the pH of all the suspensions with the increase in the coagulant dose.

The results showed that kaolin can elevate the pH level, while bentonite can lower the pH. Preparations F1 and F2 satisfy the requirements, whereas F3 fails to fulfil the standards following the pH test. F1 (5 % bentonite and 15 % kaolin) and F2 (3 % bentonite and 25 % kaolin) were optimal clay mask formulas for black glutinous rice.
