THE INTERCALATION OF Zn/Al HDL BY THE DIAMINO DODECYL PHOPHONIC ACID: SYNTHESIS AND PROPERTIES OF ADSORPTION OF CADMIUM
A B S T R A C T In this paper, Zn/Al double layered hydroxides (ZnAl LDH) were synthesized by chemical co-precipitation method and grafted with Diamino Dodecyl Phosphonic Acid (DDPA) by direct reaction and the obtained solids (ZnAl-DDPA LDH) were characterized by powder X-ray diffraction, infrared spectroscopy, BET and elemental analysis. So, the present research was aimed to study the removal efficiency of Cd2+ by ZnAl-DDPA LDHand investigated all the parameters of adsorption such as the effect of concentration of Cd2+, effect of pH, adsorbent dose, the effect of salt and temperature. The sorption data were analyzed and fitted to linearized equations of the Langmuir and Freundlich. The kinetics of sorption was analyzed by use of pseudo-first-order and pseudosecond order kinetic models.
