Abstract
The utilization of organo-modified layered double hydroxides with anionic surfactants (organo-LDHs) asadsorbents were successfully carried out to remove various synthetic dyes from aqueous solution. Intercalation of anionic surfactants changed the surface properties of MgAl-LDH from hydrophilic tohydrophobic, and a charge inversion occurred with increasing the length of surfactant chains. Suchchanges in the surface properties of the organo-LDHs were important. Experimental data shown that theSNS-modified MgAl-LDH could be used as a broad-spectrum adsorbent to effectively remove anionic,non-ionic, and cationic dyes from aqueous solution.
