a FA adsorption capacities of the investigated materials at saturation (red bars) and technical useable adsorption capacities (orange bars), measurement error bars +/− 5% in black lines. In the structural schemes, Zr clusters are represented in light blue, whereas Al clusters are in pink; (b) Experimental setup for the single-pass removal test; (c) Al-3.5-PDA extrudates; (d) FA single-pass removal efficiency (SRE) of shaped Al-3.5-PDA and activated carbon under different relative humidity levels. (test conditions: temperature: 23 °C, flow rate: 74 mL s−1, face velocity: 0.15 m s−1, the mass of adsorbent: 8 g, inlet FA concentration (C0): 0.2 mg m−3 (0.163 ppm)).
