Kinetic and thermodynamic studies on red sandalwood

摘要

Red sandalwood(Pterocarpus santalinus)has been used as a dye for wool and nylon with and without mordant. Ethanol extract of red sandalwood has been used for carrying out thermodynamic and kinetic studies on wool and nylon. The diffusion coefficients, rate of dye uptake, adsorption isotherms, standard affinity, enthalpy and heat of dyeing have been Calculated. It is observed that the red sandalwood dye has higher rate of dyeing and more affinity for nylon than those for Wool.
