Mathematical modeling of metal ions extraction process using a single drop technique

One of the main ways of determining the mechanism of the process is to study the kinetics of the process, the dependencies of the kinetics on various parameters and adopt the proper mathematical models to the obtained results. Generally, the correctness of such a course is mostly dependent on the derived model - assumptions taken, the type of solution and variables taken into consideration. This work presents a mathematical modeling of an extraction using a single drop method, where metal ions are being extracted in a form of complex with metal to extractant ratio of 1:2. This kind of complex has been observed for example in the extraction of metal dications using imidazole derivatives. Two mathematical models assuming different limiting stages of process have been derived and the course for determining the one most appropriate for individual system has been presented
