摘要： A method and apparatus are described for removing iron cations and/or zinc cations from an autodeposition coating bath by passing a limited number of bed volumes through a column containing a gel type SAC IEX resin when iron cations are to be removed and passing a substantially larger number of bed volumes through the column when zinc cations are to be removed. To prevent clogging when zinc cations are being removed the direction of the flow through the column is periodically reversed.

摘要： The use of chelating type cation exchange resins, particularly those with iminodiacetic acid functionality, to remove dissolved multivalent cations such as iron, zinc, and chromium from used autodeposition compositions permits reuse of the autodeposition compositions without the need for added surfactant and without developing any undesirable graininess or other texture in the coatings formed. The cation exchange resins can be efficiently regenerated with 0.5 to 4% by weight aqueous hydrofluoric acid.
