Bioregeneration of mono-amine modified silica and granular activated carbon loaded with Acid Orange 7 in batch system.
George Town, Malaysia. In Bioresour Technol, Aug 2012
The objectives of this study were: (1) to investigate the role of mixed culture of biomass in the regeneration of mono-amine modified silica (MAMS) and granular activated carbon (GAC) loaded with Acid Orange 7 (AO7), (2) to quantify and compare the bioregeneration efficiencies of AO7-loaded MAMS and GAC using the sequential adsorption and biodegradation approach and (3) to evaluate the reusability of bioregenerated MAMS.
CeO2 mediated photocatalytic degradation studies of C.I. acid orange 7.
Shanghai, China. In Environ Technol, Feb 2012
By selecting photocatalytic degradation of acid orange 7 (AO7) as a probe reaction, the influences of calcination temperature of catalyst, the concentration of AO7, initial pH value of AO7 solution and catalyst dosage on the photocatalytic activity of CeO2 were studied.
