本文提出在硫酸-氯化钠底液中,借硫酸铜的催化作用,于-0.75到-1.10伏处用一般经典极谱仪的导数部分测定碲-铜的催化导数极谱波,可测至3.2×10~(-8)M的碲,一般样品可测至1×10~(-5)％。实践证明本法灵敏度高,重现性好,适用于铜矿、铁矿、铅锌矿等矿石中微量碲的测定。 This paper proposes the determination of the tellurium-copper catalytic derivative polarographic wave at a derivative of a classical classical polarography spectrometer at a temperature of -0.75 to -1.10 V by the action of copper sulfate in sulfuric acid-sodium chloride at the bottom, 3.2 × 10 ~ (-8) M tellurium, the general sample can be measured to 1 × 10 ~ (-5)%. Practice has proved that the law of high sensitivity, good reproducibility, suitable for the determination of trace amounts of tellurium in copper, iron ore, lead-zinc ore.
