Disclosed are processes for the preparation of copper containing molecular sieves with the CHA structure wherein the copper is exchanged into the Na+-form of the Chabazite, using a liquid copper solution wherein the concentration of copper is in the range of about 0.001 to about 0.4 molar. Also described are copper containing molecular sieves with the CHA structure, catalysts incorporating molecular sieves, systems and methods for their use.
