Abstract: An innovative and sensitive method for extracting liquid-liquid flour using pre-mixing with the singledrop microextraction technique. This working system is distinguished by its ability to be applied to chemical and biological analyses. It is suitable for microfluidics, has a short time, is free of contaminants, and has a simple design that can be installed anywhere in the laboratory. The working system consists of several basic parts: a pump device to pump or fall back the organic and aqueous phase from the liquid-liquid micro-system through micro-rubber tubes and two precise micro-needles to generate drops, two mixers using two magnetic clamps on two graduated holders, and a precise micro-mixer to complete the mixing process. Study of the main variables in the system containing dithizone (0.0001 M). ) in CHCl₃ solvent solution and aqueous copper chloride solution (1000 ppm) to see how they affect the extraction performance obtained by this method. The effect of the copper concentration in the initial sample, the speed of the mixer, and the flow rate were discussed and studied, and the best conditions were determined: for (2 ml) sample an aqueous solution of copper (II) chloride, the optimal concentration of copper. (II) in the analyzed sample is (0.0001M), the speed of the micromixer is maximum, and the pump flow rate is (0.5 ml /sec). In these optimal conditions, the degree of extraction was (97±2%).
