| Abstract: | The characterisation of heat-treated sea
nodule leached residues by various physicochemical methods (XRD, FT-IR and
surface area measurement) and their catalytic activity towards decolourisation
of methylene blue (MB) under varying experimental conditions have been studied.
Oxidative decolourisation of aqueous MB in batches shows an increase in
decolourisation with the increase of catalyst dose, while a decrease in
activity is observed with the increase in initial pH of the solution and MB concentration. More than 85% of 10 mg/L
MB is decolourised within
30 min with a catalyst dose of 0.6 g/L at pH
~ 3. The effect of different electrolytes on catalytic activity has also been
studied.
