Selection and evaluation of adsorbents for the removal of anionic surfactants from laundry rinsing water.
Low-cost adsorbents were tested to remove anionic surfactants from laundry rinsing water to allow re-use of water. Adsorbents were selected corresponding to the different surfactant adsorption mechanisms. Equilibrium adsorption studies of linear alkyl benzene sulfonate (LAS) show that ionic interaction results in a high maximum adsorption capacity on positively charged adsorbents of 0.6-1.7 gLA...
متن کاملA review on Carbon nanotubes adsorbents for the removal of pollutants from aqueous solutions
Carbon nanotubes (CNTs) are a novel material that exhibits good adsorption behavior toward various toxic pollutants in aqueous solution. These adsorbents have a fast adsorption rate and high adsorption efficiency, efficient to remove various pollutants and they are easy to recover and reuse. These features highlight the suitability of CNTs for the treatment of water polluted with heavy metal io...

متن کاملThermal and chemical modification of bentonite for adsorption of an anionic dye
Raw bentonite (RB), a known low-cost versatile clay was used as an adsorbent. RB was treated thermally and chemically to increase its adsorption capacity. For thermal treatment (TTB), the bentonite was heated at 400 °C for 60 min, and for the chemical modification, its surface was treated by cetyltrimethylammonium bromide (CTAB) to prepare organo-modified bentonite (CTAB-B). The removal of Cong...
متن کاملSynthesis of Fe3O4/Eggshell and egg membrane Nanocomposite and Application for Adsorption of Cationic and Anionic Dyes
This work is reported on the synthesis of Fe3O4/eggshell nanocomposites in the absence of anystabilizer or surfactant. Fe3O4 magnetic nanoparticles were established on the egg shell. The adsorptionof Malachite green (MG) and Crystal violet (CV) as cationic dyes and Eriochrome Black T (EBT) as ananionic dye by magnetite nanoparticles loaded egg shell (MNLES) and magnetite nanop...
