Upgraded bentonite was activated using sulphuric acid with various acid strength of 0.05 0.5 5 and 10 M. Ratio of bentonite weight and acid volume was 1 25. The activation process was performed with three methods namely heating in 60 C for 1 hour heating for 1 hour followed by acid soaking for 1 week and acid settlement for two weeks.
The conventional process for producing acid-activated bleaching clays utilizes calcium bentonite clays and requires relatively high acid dosages to achieve maximum bleaching efficiencies. The calcium bentonites used in the process are hydrated sodium calcium aluminosilicates which typically are mildly basic.
Preparation of activated bentonite and its adsorption behavior on oil-soluble green pigment 833 sulfuric acid H 2 SO 4 dosage, microwave power, liquid-to-solid ratio and activation time. Figure 3 shows the effect of operation factors on the activity degree and decolorization ratio of activated bentonite AB.
Actal Acid Clay Catalyst. Naturally occuring Bentonite is activated with acids. During acid activation the interlayer cations are exchanged per protons and other catalytically active cations. Metal ions like Al amp Fe are leached out from octahedral layer of clay. As a result, clay becomes acidic and porous.
