Surface modified bagasse fly ash zeolites for removal of reactive black-5
Journal of dispersion science and technology, 2011•Taylor & Francis
Zeolites were synthesized form Bagasse fly ash using the mixture of sodium hydroxide and
sodium chloride by conventional as well as microwave heating, for the effective removal of
reactive black-5 from aqueous solution. The virgin and synthesized sorbents were
characterized by XRD, XRF, SEM, and FTIR. The influence of operating variables such as
pH, contact time, sorbent dose, initial dye concentration and temperature were evaluated.
The Langmuir and Freundlich isotherm model best represents the equilibrium data than the …

The virgin and synthesized sorbents were characterized by XRD, XRF, SEM, and FTIR. The influence of operating variables such as pH, contact time, sorbent dose, initial dye concentration and temperature were evaluated. The Langmuir and Freundlich isotherm model best represents the equilibrium data than the Temkin isotherms for the sorption of dye. Sorption kinetics can be best represented by a pseudo-second-order rate expression.
