Adsorption of Synthetic Dye by Betel Nuts Activated Carbon in a Fixed-bed Column, Experiments and Prediction of Breakthrough Curves

An experimental study on hydrogen sulphide (H2S) adsorption behaviours using amine-impregnated solid adsorbent (GAC/PEI) was carried out for H2S concentration in the range of 200 and 400 ppm. The dynamic adsorptions of GAC and modified GAC (2.0 and 1000 g/L PEI) in a fixed-bed column were investigated by determining the breakthrough curves and adsorption capacities of various adsorbents. The adsorbent exhibits an excellent adsorption capacity of 106.87 and 231.45 mgH2S/g-adsorbent for 200 ppm and 400 ppm H2S, respectively. The H2S breakthrough capacity is found to relate to the surface adsorption and chemical adsorption.

Granulated Tolypocladium biomass (industrial waste) was tested as mercury biosorbent in continuous mode (fixed bed column). Supplied material contained approx. 70% of fungal biomass and 30% of inert material (diatomaceous earth). Prior to column experiments, batch sorption was also performed. The results of batch experiments were compared to our previous results obtained for powdered biomass (100% biomass material) and an important drop of sorption capacity was observed. For column experiments, the bed height and flow rate were kept constant and the influence of both initial mercury concentration and bead size was investigated. The Adams Bohart, the Thomas and the Yoon and Nelson models were used for the characterization of breakthrough curves.

Abstract Biochar caged zirconium ferrite (BC-ZrFe2O5) nanocomposites were fabricated and their adsorption capacity for Reactive Blue 19 (RB19) dye was evaluated in a fixed-bed column and batch sorption mode. The adsorption of dye onto BC-ZrFe2O5 NCs followed pseudo-second-order kinetics (R 2 = 0.998) and among isotherms, the experimental data was best fitted to Sips model as compared to Freundlich and Langmuir isotherms models. The influence of flow-rate (3–5 mL min−1), inlet RB19 dye concentration (20–100 mg L−1) and quantity of BC-ZrFe2O5 NCs (0.5–1.5 g) on fixed-bed sorption was elucidated by Box-Behnken experimental design. The saturation times (C t /C o = 0.95) and breakthrough (C t /C o = 0.05) were higher at lower flow-rates and higher dose of BC-ZrFe2O5 NCs. The saturation times decreased, but breakthrough was increased with the initial RB19 dye concentration. The treated volume was higher at low sorbent dose and influent concentration. Fractional bed utilization (FBU) increased with RB19 dye concentration and flow rates at low dose of BC-ZrFe2O5 NCs. Yan model was fitted best to breakthrough curves data as compared to Bohart-Adams and Thomas models. Results revealed that BC-ZrFe2O5 nanocomposite has promising adsorption efficiency and could be used for the adsorption of dyes from textile effluents.
