Theoritical investigations have been made to calculate the nucleatiion thermodynamical parameters like interfacial energy,critical energy barriers and nucleation rate of L-Arginine tetrafluroborate using the solubility data and applying the classical nucleation theory . in the present study both classical nucleation theory and modified classical nucleation theory have been employed to study the nucleation parameters of L-AFB crystal using various solvents water, acetone & ethanol. A comparative study has been made with respect to the solvents and the results are analyzed the successful growth of large size crystals of good quality L-AFBby gradual temperature lowering technique using suitable solvent, requires knowledghe of fundamental nucleation parameters that influence the growth in super saturation. In other words optimum crystallization processes can only be accomplished if proper super saturation level and suitable solvent chosen during the growth technique is decided by the theoretical estimation of nucleation parameters based on the classical and present theory. Results are dissussed to understand the growth kinetics of L-AFB crystals from low temperature solution growth .
