The aim of this communication is to understand the different aspects and needs of the
modification of micro and meso-porous clay or clay based materials in particular to its …

This research involved the efficient adsorption of an anionic dye (Reactive Red 120) by
natural untreated clay, a low-cost material abundant in highly weathered soils. The …

Adsorption of anionic dye–Orange II–in aqueous solution onto
hexadecyltrimethylammonium bromide (HDTMA)-coated zeolite (HCZ) reached 38.96 mg/g …

Bentonite was modified with cetylpyridinium bromide (CPBr) and investigated by elemental
analysis, IR, X-ray diffraction, thermogravimetric analysis, specific surface area (BET) and …

This study investigates the possibility of applying an adsorption process using two abundant
natural minerals M1 and M2. Without pretreatment or activation, the adsorbents were used to …

In this study, natural clay was used as an adsorbent for the removal of methylene blue from
an aqueous solution. The influence of the initial dye concentration, contact time, pH …

The process of mono and binary removal of crystal violet and safranin dyes by Spirulina
sp.(blue-green algae) modified with cationic surfactant is evaluated. The surfactant used …

The present work deals with the dehydration transformation of Ca-montmorillonite in the
temperature range 30°–500° C. Thermal, infrared (IR), and X-ray diffraction (XRD) analyses …

Eight organoclays were prepared from sodium-rich bentonite and dodecylpyridinium
chloride loading levels of 0.25–2.00 times the cation exchange capacity (CEC). The …

Removal of Cr (VI) from aqueous solution by hexadecyltrimethylammonium chloride
(HDTMA) modified kaolinite (HMK) was investigated, where the maximum adsorptive …
