Removal of Dichloroethylene in Water Using a Novel TCAS-Loaded Resin

Abstract:

Through the method of the static tests, the removal rate of aqueous dichloroethylene onto a new TCAS-loaded resin was researched. This TCAS-loaded resin was made of a novel supramolecular acceptor compound named thiacalix[4]arenetetrasulfonate(TCAS) and anion exchange resin, and the adsorption mechanism was discussed preliminarily. The results of adsorption indicated that the pH value was an important factor for the removal of dichloroethylene and it would be better for the adsorption if the pH value was greater than 6. The operating temperature should be controlled in 5 to 15°C for the adsorption of dichloroethylene onto TCAS-loaded resin while the removal rate decreased with the temperature increasing and the best time for reaction was 40min. The removal rate of dichloroethylene in aqueous solution was better when 25mL aqueous solution of dichloroethylene (1.0mg/L) was adsorbed by 0.5g TCAS-loaded resin. The dichloroethylene can be resolving and TCAS-loaded resin can be reused.
