Liquid Membrane Transport Kinetics of Hg (II) by Dithio Derivatized Macrotricyclic Compound

Abstract

The present study has been undertaken to investigate a process that removes inorganic mercury from waste water streams by use of a liquid membrane system in which a novel macrocyclic ligand based on dithio derivatized biscrown ether has been used as a cation carrier. The effect of temperature, stirring rate and different solvents on the kinetic parameters like k₁, k₂ and flux values J _a ^max, J _d ^max and t_max were also investigated. It was found that the membrane entrance rate constant (k₁) and the membrane exit rate constant (k₂) increased with increasing temperature and stirring rate. The membrane entrance rate constants (k₁), exit rate constants (k₂), as well as the flux values vary in the order of CH₂Cl₂ > CHCl₃ > CCl₄ in different solvents study
