摘要： An aqueous zinc nitrite solution which contains substantially no calcium (Ca) ions is provided, in which, in terms of the aqueous zinc nitrite [Zn(NO2)2] solution having an NO2 concentration of 10% by weight, the sodium (Na) ion concentration is 200 to 2000 ppm and the sulfate (SO4) ion concentration is 20 ppm or less in the solution. The aqueous zinc nitrite solution can be prepared by providing a zinc compound and an alkali nitrite as raw materials and subjecting the raw materials to electrolytic synthesis through a double decomposition reaction using an ion-exchange membrane as a diaphragm. As the aqueous zinc nitrite solution is provided, an extremely efficient metal surface treatment is made possible which has a reduced amount of sodium ions. In particular, it contains substantially no sulfate ions and no calcium ions.

摘要： A high purity metaphosphate is characterized in that the concentration of each coloring metal element serving as an impurity is 5 ppm or less. The metaphosphate is an aluminum salt, a barium salt, a calcium salt, a magnesium salt, or a strontium salt. The aluminum salt is suitably produced by means of a production method comprising a first step of producing a reaction mixture containing aluminum biphosphate by reacting an aluminum compound with phosphoric acid by heating, a second step of placing the reaction mixture containing aluminum biphosphate obtained in the first step in a firing vessel on which aluminum metaphosphate powder is spread in advance and subjecting the reaction mixture to firing, and a third step of pulverizing the fired product obtained in the second step.
