Mg-Al Layered Double Hydroxide Doped Activated Carbon Composites for Phosphate Removal from Synthetic Water: Adsorption and Thermodynamics Studies

“…The negative or positive value of ∆S • indicates the degree of freedom of pollutant particles at the solid-liquid interface. In our case, the ∆S • was positive (31.15 J/mol/K), suggesting the increase in phosphate ions' randomness and degree of freedom at the adsorbent interface [66]. These results indicate that removing phosphate ions by AC/MgAl-3 is a favorable adsorption process.…”

Unveiling a robust and high-temperature-stable two-dimensional ZnAl layered double hydroxide nanosheet based flexible triboelectric nanogenerator

“…3b, the FTIR spectrum of the ZnAl LDH–PVA nanocomposite shows a broader peak at 3302 cm −1 , which corresponds to the stretching mode of the hydroxyl group in the PVA matrix, whereas the other peaks at 1318, 949, and 829 cm −1 confirm the presence of the LDH filler in the PVA matrix. 39,40 Moreover, other significant characteristic peaks of the PVA matrix are also observed at 2923, 1651, 1411, 1095, and 949 cm −1 . These absorption peaks are assigned to the asymmetric stretching of CH 2 , carbonyl (CO) stretching, the bending vibration of C–H bonds, and C–O and C–C stretching vibrations of the PVA polymer.…”
