Some of the current adsorbents showed over 3 mmol/g adsorption capacities in DAC conditions. Modification of resin-based adsorbent Lewatit\u00aeVP OC 1065 with tertiary amine via urea bridge will be discussed. The experimental part will concentrate on synthesis methods for commercial Lewatit\u00aeVP OC 1065 ion exchange resin.
