In this study, an outstanding anion exchange chemical filter has been prepared for acidic gas removal. Commercial anion exchange resin has been attached to polyurethane (PU) foam by using different type of pressure sensitive adhesive (PSA). Water resistance, chemical resistance and adhesive elongation have been investigated. Also, behavior of HCl and HF adsorption has been evaluated as functions of initional concentration and flow rate. ATE-701, AT-4000C and HCA-1000 showed elongation of 900%, 1500% and 2400%, respectively. It was confirmed that the desorption ratio of HCA-1000 was less than 6% and had excellent durability in water resistance and chemical resistance test. Adsorption occurred faster as concentration and flow rate of HCl and HF increased. But 100% adsorption equilibrium occurred, after 110 minutes, regardless of concentration and flow rate. |
