The capacity of mesoporous fly ash grafted with ultrathin film of polydiallyldimethyl ammonium for enhanced removal of phenol from aqueous solutions

Effective isolation of succinic acid from aqueous media with the use of anion exchange resins

“…Otherwise, i.e., when a non-linear relationship is observed, it indicates that the resin surface has more than one type of binding site (heterogeneous surface). 64 The relatively high R 2 values for the linearity reached with the Scatchard model and the agreement of q max values may indicate that the equilibrium data ts with the Langmuir isotherm model or homogenous adsorption process.…”

Bifunctional PDDA-stabilized β-Fe2O3 nanoclusters for improved photoelectrocatalytic and magnetic field enhanced photocatalytic applications

“…The FTIR spectrum of PDDA exhibited typical bands at 3448, 2939, 2872, 1645, 1475, and 1244 cm −1 . [38][39][40] The broad band at around 3400 cm −1 is due to the O-H stretching of moisture present in the sample. 41 The FTIR spectra of both the PDDA and β-Fe 2 O 3 @PDDA nanoclusters show the bands at around 2900, 2850, and 1400 cm −1 , which are attributed to the C-H group.…”

Progress in Emerging Contaminants Removal by Adsorption/Membrane Filtration-Based Technologies: A Review

“…The performance was strongly influenced by pH with an optimum value of 6, and the mechanism was well described by the Freundlich isotherm and pseudo-second-order kinetic models. Oyehan et al, (2020) investigated phenol removal by a mesoporous fly ash-based adsorbent. It was coated by an ultrathin film of polydiallydimethyl ammonium chloride.…”
