Dynamic Adsorption of As(V) onto the Porous α-Fe2O3/Fe3O4/C Composite Prepared with Bamboo Bio-Template

Arsenic (As(V)), a highly toxic metalloid, is known to contaminate wastewater and groundwater difficult degrade in nature. However, the development of efficient adsorbents, at low cost for use practical applications, remains challenging. Thus, investigate As(V) adsorption mechanism, novel porous α-Fe2O3/Fe3O4/C composite (PC-Fe/C-B) was prepared, using bamboo side shoots as bio-template, breakthrough performance PC-Fe/C-B composite-packed fixed-bed column removal evaluated, simulated wastewater. The material accurately retained hierarchical microstructure bio-templates, results demonstrated great potential composite, an effective adsorbent removing from wastewater, under optimal experimental conditions of: influent flow 5.136 mL/min, pH 3, concentration 20 mg/L, particle size < 0.149 mm, temperature 35 °C, dose 0.5 g, time 50 min (184 BV), with qe,exp 21.0 mg/g fixed-bed-column system. CD-MUSIC model effectively coupled transport model, PHREEQC software, simulate reactive transportation predict curve adsorption.
