摘要：The Purification of phosphoric acid used several extractants from the family of oxygenates, sulfurous or amino compounds. In this work, we were interested in the synthesis, physico-chemical and spectroscopic characterization, and use of the product C11H18N2O as an extractant of cadmium from phosphoric acid. The synthesized product was characterized by: infrared spectroscopy, nuclear magnetic resonance, and mass spectroscopy. Solubility tests in different solvents have been carried out. Subsequently, liquid-liquid extraction of cadmium from phosphoric acid was carried out using C11H18N2O as an extractant diluted in benzene. The study investigated the influence of concentration of phosphoric acid and the extracting agent. The result obtained ensure that our synthesized product is promising. The percentage of cadmium extraction from phosphoric acid reached 98.58% at a concentration of 2.5M phosphoric acid and an optimal concentration of 0.5×10-2 M of synthesized extractant.
