Abstract
PURPOSE: To obtain a sulfamic acid lead plating liquor having highly stable electric deposition characteristics and easier waste water treatability and containing lead sulfamate, sulfamic acid, a specific amount (on the basis of sulfamic acid) of a water-soluble alkaline compound, and water.
CONSTITUTION: An aqueous solution containing lead sulfamate and sulfamic acid is prepared by dissolving a lead salt in an aqueous solution containing an excess (based on lead) of sulfamic acid, where 0.8W1.0mol. of a water-soluble alkaline compound, e,g., one or more of NaOH, KOH, and NH4OH, is added on the basis of 1mol. of sulfamic acid in order to stabilize the plating liquor.
