Abstract
A process is provided for the removal of undesirable organic matter from solutions of sodium nitrite that are generated as byproducts in the manufacture of thermoplastic resins. The process employs certain activated carbon types derived from lignite granular material under conditions that are favorable to promote the absorption of the organic matter of a variety of organic substances that are residuals that remain from organic phase specifications in the plastics manufacture.
