Adsorption of an anionic dye from aqueous solution on a treated clay
(Elsevier, 2021-11)
The presence of synthetic dyes in water causes serious environmental issues dueto the poor water quality, toxicity to the environment and human carcinogenic effects.Adsorption has progressively become an economical and ...
Improvement in the Adsorption of Anionic and Cationic Dyes From Aqueous Solutions: A Comparative Study Using Aluminium Pillared Clays and Activated Carbon
(Taylor & Francis, 2013-11-14)
The aim of this work was to evaluate the adsorption properties of anionic dye Reactive Black 5 (RB5) and cationic dye Methylene Blue (MB) from salted aqueous solution using natural clay, aluminum pillared clay (Al-PILC), ...
Preparation of a clay-modified carbon paste electrode based on 2-thiazoline-2-thiol-hexadecylammonium sorption for the sensitive determination of mercury
(2005-11-01)
A montmorillonite from Wyoming-USA was used to prepare an organo-clay complex, named 2-thiazoline-2-thiol-hexadecyltrimethylammonium-clay (TZT-HDTA-clay), for the purpose of the selective adsorption of the heavy metals ...
Preparation of Cd/Al layered double hydroxides and their intercalation reactions with phosphonic acids

Adsorption of picloram on clays nontronite, illite and kaolinite: equilibrium and herbicide-clays surface complexes
(Taylor & Francis, 2019-04)
The picloram (PCM) adsorption on nontronite, illite and kaolinite was studied at pH 3, 5 and 7. The adsorption isotherms had well-fitted to Langmuir and Freundlich models equations. The interactions of PCM with the clay ...
Surfactant modified clays’ consistency limits and contact angles
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2012)
This study was aimed at preparing a surfactant modified clay (SMC) and researching the effect of surfactants on clays' contact angles and consistency limits; clay was thus modified by surfactants formodifying their engineering ...
