Photo-catalytic degradation of toxic dye amaranth on TiO2/UV in aqueous suspensions
Vinod Kumar Gupta,Rajeev Jain,Alok Mittal,Tawfik A. Saleh,Arunima Nayak,Shilpi Agarwal,Shalini Sikarwar +6 more
TL;DR: The photo-catalytic degradation of an azo dye - Amaranth (AM) - has been investigated in TiO(2)/UV aqueous suspensions and it was observed that decolorization rate increased by the increase in temperature and the lower the pH the higher the degradation.

Removal of congo red from aqueous solution by bagasse fly ash and activated carbon: Kinetic study and equilibrium isotherm analyses
TL;DR: Thermodynamics showed that the adsorption of CR on BFA was most favourable in comparison to activated carbons, and the R-P isotherm best-fits the CR adsorbent data on all adsorbents.
