The invention discloses a jewelry white surface treatment plating solution, a preparation method and an
electroplating method thereof. The preparation method comprises the steps that about 90 g of
ammonium sulfamate and about 20 g of
nickel aminosulfonate are weighed and poured into a 1 L
beaker; 700 ml of water is added for
dilution and
dissolution; a stirrer is added, the
beaker is added into a thermal-collection type constant temperature heating
magnetic stirrer for performing heating and stirring for 40 min; the mixture is taken out, and then dinitroso-
diamine palladium is added, wherein the content is
palladium is about 6 g; water is added to reach about 950 ml and the mixture is added into the thermal-collection type constant temperature heating
magnetic stirrer for performing heating and stirring for 15 min; the
beaker is taken out, a solution is filtered, the filtered solution is subjected to testing of PH value through PH paper of the specification of 6-9, if the PH value is 8-9, the plating solution is obtained; if the PH value is not 8-9, a dropper is used for taking
ammonium hydroxide, a half amount of the
ammonium hydroxide in the dropper is added, a glass rod is used for performing stirring for 203 min, then, the PH value is tested, and the steps are repeatedly executed till the PH value is 8-9; finally, pure water is added to supplement the solution to reach 1 L so that the plating solution can be formed.
