In a procedure for electrolytic dissolving pure copper and common brasses,the approximate electrochemical mole mass(k) of the sample was determined in accordance with the brand of the sample,a suitable electrolyte was selected to make the current efficiency equal to 100%,and then the dissolved mass of samples was calculated according to Faraday's law (m=kIt).Three representative samples were sampled by the electrolytic dissolution method and the calculated dissolved amounts were equal to the values by weighing the anode.The experimental results of zinc and copper in the anode liquor are in agreement with certified values.
