Abstract
Innovative, sensitive and accurate method for liquid-liquid extraction using an ultrasonic device is presented in this work. A working system was created, consisting of two basic components: the ultrasonic device and the pump device, to pump or withdraw the organic layer A study of the key variables derived from the liquid-liquid system was carried out in the system containing Dithizone (1×10^-3 M) in (Chloroform) CHCl₃ solvent. and aqueous copper (II) chloride(CuC2.2H2O) (1×10^-6 M) solution to determine the degree to which they affect the extraction performance attained in this manner. The effect of initial sample copper concentration and ultrasonic time, temperature effect, pump speed, were studied, establishing the best conditions for a sample of (10 mL) aqueous solution of Cu (II) chloride, the optimum copper (II) concentration in the analyzed sample is (1×10^-6 M), the ultrasonic time for the device is (8 min), and the flowrate of the pump is (3mL/30sec) and a temperature (27ºC) and (pH=1). The extraction degree was optimum under these conditions (96±2%). The innovative ultrasonic extraction method's results were compared to previous studies, and they were found to be more efficient than the traditional methods of extraction using funnel separation and multiple extraction.
