The Effect of Chloride and Sulfate Ions on the Adsorption of Cd2+ on Clay and Sandy Loam Egyptian Soils
Adsorption of Cd(2+) on two types of Egyptian soils: clay (alluvial) and sandy loam (calcareous), was studied. Effect of changing the matrix electrolyte type and concentration was used to mimic the natural soil salts. Kinetics and thermodynamic parameters of the adsorption were calculated at two different electrolyte concentrations: 0.05 N and 0.15 N. The adsorption was described by Langmuir an...
متن کاملvalorization of tunisian pottery clay onto basic dyes adsorption
this study examined the adsorption behavior of two cationic dyes used in textile industries (cibasic red 46 and ci basic blue 3) on tunisian clay used in pottery. the ability of pottery clay to remove thebasic dyes from aqueous solution was compared to that of the commercial powdered activated carbon (pac)and raw clay. physicochemical characteristics of these adsorbents were performed by boehm ...
متن کاملDFT Study of N-hydroxyurea Adsorption Behavior onto Pristine and Iron-doped Single-walled Carbon Nanotube
The interactions between N-hydroxyurea (NHU) as anticancer drug and SWCNTs (pure and Fe-doped) were investigated with density functional theory. In this study, large long-range corrected CAM-B3LYP and B3LYP were employed to investigate the stability of the different NHU-CNT and NHU/Fe-CNT complexes in the gas phase and solution (water). The presence of an iron atom would create suitable space o...
متن کاملThe competitive adsorption of human proteins onto natural-based biomaterials.
This study aims to further the understanding of nanoscale structures relevant for cellular recognition on contact and interaction with natural-based materials. The correlation between surface characteristics and protein adsorption from unitary and complex protein systems was investigated with respect to altering the bulk chemistry of the substrate material. Polymeric blends of starch and cellul...
متن کاملNanoporous Xerogel for Adsorption of Pb2+ and Cd2+
Classical xerogels are robust, inexpensive and nontoxic materials with low-ordered nanoporous structures. In water streams where the pH is higher than the Point of Zero Charge, the surface of classical xerogels such as tetraethoxy orthosilan (TEOS) xerogel is negatively charged. It was assumed that a xerogel can work as a strong adsorbent for metal ions without further modification. Therefore, ...
