示波极谱法测定锑金矿中锑的研究

Oscillopolarographic Determination the Antimony of Antimony Gold

以盐酸一乙酸为底液示波极谱法测定锑。用酒石酸、硝酸、硫酸分解样品，加入抗坏血酸还原铁，加明胶抑制极大，在酸性底液极谱三电极系统中，-220mv处测量锑，加标回收率99．34％，100．48％，锑的测定范围为0．01％-15％。实验证明，此方法快速简便，成本低，是测定锑矿中锑的有效方法。

Experiments selected hydrochloric acid - acetic acid the base solution Oscillopolarographic determination of Antimony. Sample decomposition with tartaric acid, nitric acid, sulfuric acid, ascorbic acid and reductive iron, gelatin suppressed greatly. In acidic basic liquid and a polarographic three-electrode system, and at-220mV samples are measured. The recoveries of 99.34% - 100.48% meet the requirements. Determination of Antimony in the range of 0.01% -15% is showed that this method is quick, easy and low cost method for determination of antimony ore.
