Abstract:Competitive adsorption of Pb 2+ , Cd 2+ and Zn 2+ ions on sodium dodecyl sulfate (SDS) in binary mixtures were investigated compared with non-competitive adsorption in the unitary metal solution in micellar-enhanced ultrafiltration at a temperature of 25 • C. Mutual interference effects were investigated based on the removal rate, the Langmuir Competitive Model (LCM) and equilibrium adsorption capacity ratios, q e /q m , which indicated the presence of other metal ions. The results indicated that the removal rate and adsorption capacity of Pb 2+ were higher than that of the other metal ions in unitary and binary systems. The effects on SDS micelles for Cd-Pb and Zn-Pb combinations were found to be antagonistic. However, it was a favorable effect for the Cd-Zn combination, and the metal ions sorption followed the order: Pb 2+ > Cd 2+ > Zn 2+ . The behavior of non-competitive and competitive adsorption for Cd 2+ and Zn 2+ in a single system and in the presence of Pb 2+ were well described by LCM. Moreover, the LCM showed poor fitting to non-competitive and competitive adsorption of Pb 2+ in a single solution and in the presence of Cd 2+ or Zn 2+ . In conclusion, the removal of Pb 2+ in the presence of Zn 2+ or Cd 2+ showed greater efficacy than that of Cd 2+ or Zn 2+ in the presence of Pb 2+ .

“…Another effective method is micellar extraction with micellar-enhanced ultrafiltration (MEUF) [9][10][11][12]. When an anionic surfactant such as sodium dodecylsulfate (SDS) is added to water above the critical micelle concentration (CMC), surfactant monomers aggregate to form negatively charged micelles.…”

“…The use of surfactants can enhance removal efficiency of membrane as the formation of micelle can capture metal ions and form molecule complexes, resulting in a reduction of high pressure needed for membrane permeation. Many types of surfactant are used to improve the ability of heavy metal ion removal in any treatment processes, such as, polyoxyethylene nonyl phenyl ethers [12], sodium dodecyl sulfate (SDS) [13], surfactin [14], rhamnolipid [14], etc. High removal efficiency greater than 90% can be obtained for this technique, however, large amount of surfactants used and less capability of continuous operating due to membrane blockage are the drawback of this technique [14,15,16].…”

Abstract. This paper presents an application of surfactants extended to environmental remediation. The promising process related to the use of surfactants for heavy metal sequestration purpose named "modified-functionalized nanoporous materials" is summarized in this work. The unique characteristic of high selective of the functional groups and large surface area of nanoporous support makes this material becomes a powerful tool for sequestration of target metals. The strength of this adsorbent is fast sorption kinetic, high thermal and chemical stability, easy handling, and the ability to regenerate.
