KINETICS STUDY OF AU(III) ADSORPTION ON GALLIC ACID INTERCALATED MG/AL-HYDROTALCITE

A Comparative Study on Adsorption of Gallic Acid onto Polymeric Adsorbents with Amine Functional Groups

The paper studies the adsorption of gallic acid from kinetic and thermodynamic perspectives, using several synthesized polymers with amine functional groups. These compounds, defined as P1, P115, P-Ba 2 and PHH, and obtained by appropriate chemical transformation reactions on crosslinked pyridine and acrylic copolymers, were characterized by weight and volume exchange capacities, their values b...

Adsorption of Arsenic on MgAl Layered Double Hydroxide

Groundwater in the Eastern Croatia, as well in the South-eastern Hungary, contains relatively high concentrations of arsenic that can cause chronic toxicity to humans. Therefore, the aim to find an effective composite adsorbent that can be applied for arsenic water remediation by introducing it in the groundwater treatment is very important. The presented results were obtained using layered dou...

Hydrotalcite Intercalated siRNA: Computational Characterization of the Interlayer Environment

Using molecular dynamics (MD) simulations, we explore the structural and dynamical properties of siRNA within the intercalated environment of a Mg:Al 2:1 Layered Double Hydroxide (LDH) nanoparticle. An ab initio force field (Condensed-phase Optimized Molecular Potentials for Atomistic Simulation Studies: COMPASS) is used for the MD simulations of the hybrid organic-inorganic systems. The struct...

Preparation of Gallic Acid Loaded Biodegradable Polymeric Nanogels and Study of its Release Kinetics

Optimization of CO2 adsorption capacity and cyclical adsorption/desorption on tetraethylenepentamine-supported surface-modified hydrotalcite.

The objective of this research was to investigate CO2 adsorption capacity of tetraethylenepentamine-functionalized basic-modified calcined hydrotalcite (TEPA/b-cHT) sorbents at atmospheric pressure formed under varying TEPA loading levels, temperatures, sorbent weight to total gaseous flow rate (W/F) ratios and CO2 concentrations in the influent gas. The TEPA/b-cHT sorbents were characterized b...
