Layered Rare-Earth Hydroxide Unilameller Nanosheets: Synthesis, Characterization, and Adsorption

Figure 12

Recycling of the synthesized LEuH adsorbent in fluoride adsorption from aqueous solutions; 100% q_{max =} 40 mmol/g; pH = 7; temperature = 298K; mass of sorbent = 0.2 g. In cycle 1, we used LEuH-flocs, and in the subsequent cycles, we use LEuH-spinels obtained after calcination of LEuH-flocs at 500°C as sorbent materials.
