Reactive Polymers in Mercury Removal from Electrolytic Brine

The adsorption of mercury from concentrated aqueous solutions and chlor-alkali industry brine on the reactive polymers has been studied. The investigations were performed in the batch and column systems. The batch experiments were carried out to assess mercury ion exchange adsorption isotherms and adsorptive capacity. The effects of agitation time and pH were investigated. On the basis of dynamic experiment results, mercury concentration in the effluent obtained from the column against the flow rate of brine through the bed was deduced and the effective and total capacities were calculated. The regeneration of the spent resins was also investigated.
