Use of cationic surfactants in surface modification of magnetic nanoparticles for adsorption of organic dyes from aqueous solutions
The cationic C(16)H(33) Me(3)NBr, PhCH(2) Me(2)C(12)H(25)NCl and hexadecylpyridinium chloride surfactants were synthesized and deposited on magnetic Fe(3)O(4) nano particles to produce adsorbents used for removing methylene blue, crystal violet and methyl orange from their aq. solns. The highest degree of the dye removal was achieved when the nanoparticles were modified with the hexadecylpyridinium surfactant.
