| titleOfInvention | Method for measuring trace metal copper and zinc in nickel-cobalt solution |
| abstract | The invention discloses a method for measuring trace metal copper and zinc in a nickel-cobalt solution, which comprises the steps of filtering the nickel-cobalt solution by using a microporous filter membrane, enabling a metal simple substance in the nickel-cobalt solution to remain on the filter membrane, then selectively dissolving the metal copper, zinc or an alloy thereof on the microporous filter membrane by using ammonia water, enabling the metal copper and zinc on the filter membrane to enter the solution, measuring the copper and zinc in the solution by using an atomic absorption spectrum or a plasma spectrum after treatment, and obtaining the content of the metal copper and zinc in the solution. The method has simple process, can effectively detect trace metals of copper and zinc in the solution, has accurate and reliable detection result, and can directly return the treated solution to a production line without causing material waste. The method is suitable for measuring trace metal copper and zinc in nickel sulfate, cobalt chloride, cobalt nitrate, cobalt sulfate and nickel-cobalt mixed solution or mixed solution mainly containing nickel and cobalt and other metals. |
