Abstract:

The development of nanotechnology has been intensively in recent years and consequently innovative methods have been used. Nanoscale magnetic particles brings a high performance in separation processes due to its high specific surface area and the absence of internal diffusion resistance, moreover they also can be easily recovered with an external magnetic field. Surface modification of magnetic nanoparticles is a challenged key for different applications and can be accomplished by physical/ chemical adsorption of organic compounds. Dyes, pigments and others contaminants present in wastewaters from various industrial branches, such as petroleum industry, represent one of these problematic groups. Palygorskite nanoparticles Fe(III) adsorbed samples were covered by magnetite by a co-precipitation technique using FeCl 3 .6H 2 O and FeCl 2 .4H 2 O in basic medium magnetizing them. FTIR, TGA, X-ray diffraction and SQUID magnetometer analysis were used to characterize these particles. The results showed strongly support this phase transformation
