PURPOSE:To make possible the simple, quick and exact measurement of an indium concn. by using a standard indium soln. and measuring the indium concn. in an indium plating liquid by an atomic absorption calibration curve method. CONSTITUTION:The standard indium soln for atomic absorption analysis characterized by the liquid compsn. consisting of indium chloride, potassium cyanide, potassium carbonate and water is used. The indium concn. in the indium plating liquid is measured by the atomic absorption calibration curve method, by which the influence of matrix in the stage of atomic absorption analysis is decreased and the interference is lessened. The exact measurement of the indium concn. is thus made possible. |
