Synthesis And Development Of Metal Extractants

摘要

In synthesis and development of a metal extractants, yield and purity of the product are very important. There are various means of achieving this twin objective but the most attractive way is to gain the better understanding of the process and process parameter itself and then to improve and regulate them for optimum yield and purity. This approach needs quick and accurate methods for evaluating the design and operation of the process. A computer added simulation is suited for this purpose. This, in turn, needs a mathematical model, which is developed on the basis of sound theoretical knowledge about the system or on the extensive experimental data. Various reaction modeling approaches such as equilibrium constant method, Gibbs's free energy minimisation and reaction kinetics are discussed in this paper. Theoretical modeling approach needs to have reliable and accurate physical, chemical, thermodynamics and kinetic data. In the absence of these data, system can be model using black box approach. Various experimental methods are also outlined to achieve the desired objectives
