Adsorption of Methylene Blue from Aqueous Solution by AB-8 Macroreticular Resin

MATEC Web of Conferences, 2016
Study on adsorption kinetics and thermodynamics of methylene blue by AB-8 macroreticular resin was carried out through static experiments. The results showed that the adsorption rate for the solute appear to be the first order kinetics, the intraparticle

The Effectiveness of Magnetite Modified Gallic Acid Synthesized by Sonochemical Method As AuCl4- Adsorbent-Reductor

Indonesian Journal of Chemical Research, 2021
In recent years gallic acid has been developed as an AuCl4- adsorbent-reducing agent. In this research, gallic acid was modified with magnetite by sonochemical method (GA-Fe3O4), and its effectiveness as an AuCl4- adsorbent was studied.

From Car Parking to Protein Adsorption: An Overview of Sequential Adsorption Processes

, 1999
The adsorption or adhesion of large particles (proteins, colloids, cells, >...) at the liquid-solid interface plays an important role in many diverse applications. Despite the apparent complexity of the process, two features are particularly important: 1)

Adsorption Kinetics of Banana Stem Activated Carbon in Reducing Phosphate Levels

Jurnal Kesehatan Lingkungan
Introduction: High levels of phosphate in water are caused by wastewater pollution such as laundry waste water causing eutrophication. Adsorption is a method that can be used to reduce phosphate level.

Kinetic and Thermodynamic Studies on the Phosphate Adsorption Removal by Dolomite Mineral

Journal of Chemistry, 2015
The efficiency of dolomite to remove phosphate from aqueous solutions was investigated. The experimental results showed that the removal of phosphate by dolomite was rapid (the removal rate over 95% in 60 min) when the initial phosphate concentration is ...

Thermal desorption of ammonia from crystalline forsterite surfaces

, 2015
The thermal desorption of ammonia (NH$_3$) from single crystal forsterite (010) has been investigated using temperature-programmed desorption. The effect of defects on the desorption process has been probed by the use of a rough cut forsterite surface ...

Generalized Fick Jacobs Approach for describing Adsorption Desorption Kinetics in Irregular Pores under Non Equilibrium Conditions

, 2016
We present a study exploring the range of applicability of a generalized Fick Jacobs equation in the case when diffusive mass transport of a fluid along a pore includes chemical reactions in the bulk and pore surface.
