    摘要: Methods to control manganese deposition in an aqueous system, which include introducing a cerium-containing composition, and optionally another deposit control agent, to the aqueous system, are described. Also described, are cerium-containing compositions that promote the manganese stabilization performance of polymeric dispersants and phosphonic acids commonly used in water treatment applications. Cerium-containing compositions that can inhibit the oxidative degradation of deposit control agents are also described.
