Design of a new home-made ultrasonic extraction system

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(CuCl2.2H2O) (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, and 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 flow rate of the pump is (3mL/30sec) and a temperature (27ºC) and (pH=1). The extraction degree was optimum under these conditions (96±2%) and the relative standard deviation (RSD)% (0.29%), In this work, a simple method is proposed to extract and concentrate copper in aqueous copper chloride using an ultrasonic device in the presence of dithizone solvent. The main parameters affecting the extraction method such as copper ion concentration, pump speed, temperature, device time, and the effect of equal and different volumes were evaluated. The proposed method was applied for the determination of copper in aqueous copper chloride samples. Accuracy was assessed by comparing the results with a conventional extraction method (traditional methods).
