Abstract

The objective of this work was to examine possible application of biomass fly ash (BFA) for removal of ionic, toxic and carcinogenic diazo dye (Congo red) from aqueous solutions. Biomass fly ash is a by-product generated during mixed wood biomass combustion in 1 MW electric power facility in Udbina, Croatia. Batch sorption experiments were carried out to evaluate the influence of experimental parameters such as initial dye concentration (10–80 mg/L) and contact time (0–240 min) on the sorption process. The kinetic experimental data at different initial Congo red (CR) concentrations (20, 40 and 60 mg/L) were fitted by Lagergren’s pseudo-first order and Ho’s pseudosecond order model. The mechanism of the adsorption process was determined from the intraparticle Weber–Morris diffusion model. Results of the kinetic studies showed that sorption of CR dye onto biomass fly ash was best described by the pseudo-second order kinetic model.
