Efficient adsorption and desorption of (R,S)-2,3-dichloro-1-propanol by HZ-818 resin from waste water.

A macro porous resin-based separation method for (R,S)-2,3-dichloro-1-propanol removal from waste water and subsequent recovery from the resin was efficiently developed. The adsorption efficiency of four macro porous resins was evaluated. The results indicated that the resin HZ-818 has higher adsorption and desorption efficiency. After identifying the better eluent (ethanol) and optimum temperature (25°C), we achieved 100% separation of (R,S)-2,3-dichloro-1-propanol from the aqueous phase and recovery from the resin. Ethanol was also better to avoid damage on the structure of resin and to regenerate the resin for reuse. The method established has also a potential to be applied in the bioremediation of 1,2,3-trichloropropane contaminated waste water in larger scale by removing the (S)-2,3-dichloro-1-propanol.
