Abstract: | The standard addition and standard subtraction methods are discussed briefly. Both methods are applied to the determination of copper(II) in very small sample volumes. A microcell (25 μl) and a copper-selective micro-electrode are described for this purpose; a nanoliter burette was constructed for the addition of very small increments. The results are compared with those obtained in a 10-ml cell. |
