Ability of a montmorillonitic clay to interact with cationic and anionic dyes in aqueous solutions

Systematically Exploring Molecular Aggregation and Its Impact on Surface Tension and Viscosity in High Concentration Solutions

“…Reactive dyes, one kind of important organic dyes, are mainly used for dyeing and printing natural fabrics [18]. These dye molecules contain water-soluble groups (usually sodium sulfonate), and have good water solubility [19], but the dye molecules still tend to aggregate by self-association of the hydrophobic π-π conjugated parts of the molecular structure [20][21][22][23][24], which will lead to the formation of dimers, trimers [25], etc. The aggregation of dyes dilute solution has been investigated by many methods, such as, polarography [26,27], conductometry [28,29], UV-Vis [30][31][32][33], NMR [34], light scattering [35][36][37] measurements.…”

One-step preparation of a novel SrCO3/g-C3N4 nano-composite and its application in selective adsorption of crystal violet

“…[43][44][45] However, certain deciencies including costly, intricate pre-treatment and low adsorption capability limited the use of some certain adsorbents. [46][47][48][49][50][51][52][53] Due to the conjugated region, stacking structure and the weak forces of g-C 3 N 4 , it has the potential for aggregating functional groups or materials to form nanocomposite with multiform favorable properties. [54][55][56] This distinctive structure has drawn great interesting in improving the photocatalytic performance.…”

The Thermodynamics of Heavy Metal Sorption onto Lignocellulosic Biomass

“…The selection of this model was supported by the fact that it is considered as more general than Langmuir and it does not rely necessarily in the formation of a homogenous monolayer surface or a constant adsorption potential. D-R model has been used by several authors to distinguish between physical and chemical adsorption onto different biomaterials [28,29]. This model can be linearized and described by the next equation:…”
