“…T HE effect of gradual addition of alkali on the pH of dilute H-clay suspension has been studied 1 • 2 • Mukherjee and Mitra 1 have shown that kaolinite shows two inflections at pH 7-8 and 8-9.5 in its titration curve {pH-neutralisation curve) whereas montmorillonite manifests only one inflection between pH 7.1-8.8. The reverse character is also observed in some of these minerals 1 • 3 • 4 • This variation has been found to be primarily due to the differences in their surface area and base exchange capacity 4 • Unlike kaolinite and montmorillonite, the pH neutralization curves of illite and muscovite have three inflections 2 ; the first one is at pH 6, that of second at about pH 8 and third one is at above pH 11.…”

9 pH-neutralisation curves of some natural clay samples containing inters/ratified illite-montmorillonite minerals have been studied. It has been observed that their titration curves are d(fferent from those of kaolinite, montmorillonite, illite and their natural mixtures. Unlike these, the titration curves of samples containing interstratified minerals show four inflections at pH ranges 5-6, 7-7.5, 8-9.5 and 10-10.5. The role of associated clay and non-clayey materials on the nature of their titration curves has been discussed. It has been observed that their influence is not very markedly manifested on these curves and hence the titration characteristics of these samples have been ascribed as due to inters/ratified illite-montmorillonite minerals mainly. Reasons for the polybasic character of their curves have been discussed in relation to the surface area of the samples and their crystal structure.

“…The Zn retained represents about 20%, 19%, and 40% of the total exchangeable cations for these minerals. Mukherjee and Mitra (1946) have shown that a single cation may be held by a clay mineral with a wide range of bonding energies, and this is fundamentally related to the position on the silica^alumina packet at which the cation is sorbed. Accordingly, there are numerous types of energetically heterogeneous sites on these minerals.…”

Clay minerals such as kaolinite, illite, nontronite and montmorillonite werc complcxed with niethylenc blue, Malachite green and piperidine and their behaviour when heated was followed by differential thermal and thermogravimetric analysis. The results indicated that organic cations adsorbed on the broken bonds being easily accessible to oxygen are oxidised exothermally between 150 and 500". The cations adsorbed in the interlayer are oxidised in the range 500 t o 800" and this corresponds to the temperature at which thc (OH) water is expelled from the clay minerals.
