Freundlich and Langmuir isotherms have always been developed using changes in absorbance of oils. In this study we have investigated use of changes in turbidity of oils to assess bleaching efficiency and develop Freundlich ...

The Langmuir isotherms of 1-aminobutane in isohexane slurries showed increase in clay acidity with increase in concentration of mineral acid used to leach the clay as well as the temperature at which the clay was thermally ...

The decrease in content of iron in the bleached oils was highest for all oils bleached. The content of copper showed the smallest change. The decrease in copper content for palm oils decreased from 0.2ppm to 0.1ppm when ...

Natural clays occur as mixtures of many clay minerals and remains of the rocks that underwent diagenesis to yield the clays. As weathering of clay soils never ceases it may not be possible to mine single clay minerals. The ...

The results on the elemental and mineralogical compositions of clays from Central Uganda differed from those from the volcanic sediments of the Mt. Elgon in Eastern Uganda. Utilisation of the two types of clays should ...
