AbstractThe hydrotalcite-like compounds with [Mg 3Al(OH) 8][CH 3(CH 2) 10CH 2SO 4]·nH 2O (HT-DDS) and [Mg 2Al(OH) 8] 2[OOC(CH 2) 8COO] nH 2O (HT-SEB) chemical formula were studied to investigate their potential adsorption properties for the uptake of the widely used non polar pesticide Linuron from water. Adsorption experiments were carried out under different experimental conditions, such as pH, contact time and pesticide concentration. Results show the efficiency of HT-DDS and HD-SEB for Linuron adsorption which was quick, pH independent and higher for HT-SEB than for HT-DDS. The adsorbents and the adsorption products were characterized by XRD technique, FT-IR spectroscopy and TG analysis confirming the presence of Linuron in the adsorption products.
