Adsorptive Removal of Rhodamine B Using Novel Adsorbent-Based Surfactant-Modified Alpha Alumina Nanoparticles

Figure 1

The ζ potential based on adsorption isotherms of the SDS onto α-Al₂O₃ nanoparticles at pH 5.0 and under different ionic strengths of 1 and 10 mM NaCl. The standard deviation was taken by the three different measurements.
