High cost of importation of bleaching earths has necessitated for their alternative source
from locally abundant clay minerals. Ukpor clay was chosen due to its abundant nature. It …

Structural modification of clay minerals is necessary to improve their applicability. Bentonite
from Nkaliki was treated with different concentrations of sulphuric acid ranging from 0.5–5.5 …

This study was aimed at analyzing the physicochemical properties of clay mineral from Nteje
after sulphuric acid activation. The clay was grinded to a particle size of 0.212 mm and …

The structural and bleaching properties of nitric acid-activated Nteje clay was studied to
investigate its ability to serve as an alternative to the high cost imported bleaching earth. The …

Natural clays are acquiring prominence as low-cost adsorbent over the past few decades
due to their local and abundant availability and capability to undergo modification. The use …

The optimization of the bleaching effi ciency of acid-activated Ntezi bentonite was studied by
reacting raw bentonite with different concentrations of hydrochloric acid solution for varying …

Bentonite from Ntezi was modified by reacting it with different concentrations of hydrochloric
acid solutions. The modified samples were analysed by x-ray fluorescence. The kinetics of …

This study analyzed the structural transformations and adsorption properties of Ukpor clay
after nitric acid activation. The clay samples were mined, sun-dried, sized, and reacted with …

This study analyzed the effects of sulphuric acid (H2SO4) treatment on pysico-chemical
properties and morphological changes of clay obtained from Sg. Sayong, Perak. The clay …

The use of locally sourced materials as adsorbents has been investigated as a result of high
cost of bleaching clay for the purpose of bleaching vegetable oils. Consequently, shells such …
