Anion exchange removal of Al3+ from Li+-Al3+ aqueous solution (originating from lithium recovery from brine)

Efficiency of Aptenia Cordifolia Mucilage in Removal of Anion Dyes from Aqueous Solution

Dye-containing wastewater is one of the main environmental challenges that can cause health issues. It is crucial to remove the dyes from wastewater before its discharge into the environment. This study aims to evaluate the efficiency of aptenia cordifolia mucilage in removal of anionic dyes from textile wastewater via coagulation and flocculation process. To this goal, the effect of different ...

Removal of Congo Red from Aqueous Solution by Anion Exchange Membrane (EBTAC): Adsorption Kinetics and Themodynamics

The adsorption behavior of anionic dye congo red (CR) from aqueous solutions using an anion exchange membrane (EBTAC) has been investigated at room temperature. The effect of several factors including contact time, membrane dosage, ionic strength and temperature were studied. Kinetic models, namely pseudo-first-order and pseudo-second-order, liquid film diffusion and Elovich models as well as B...

Removal of Copper from Aqueous Solution by Ion Exchange Resins

Removal of Cationic Dyes from Aqueous Solution using Organomodified Nanoclay

In this work, organomodified nanoclay has been used as the adsorbent for the removal ofbasic blue 41, cationic dye from an aqueous solution. The performance of the organomodified nanoclay was tested in a batch system under varying pH (2–12), adsorbent dosage (0.1–2 g L-1), initial dye concentration (10–60 mgL-1), and contact time (5- 100 min). The best conditions were achieved at pH of 7,...

Removal of Heavy Metals from Aqueous Solution by Mordenite Nanocrystals

This study examined the ability of the synthetic mordenite nanocrystal to remove Tl(III) and As(III) from an aqueous solution. The determination of the concentration changes of H+ and OH- quantities in the acidic (pH 3) and alkali (pH 9) treated mordenite nanocrystals were done by the potentiometric titration curves. The maximum uptake capacities (Qmax) of these metal ions using the mordenite i...
