摘　　要：为了快速测定矿石中的锡含量,采用示波极谱法试验。以氯化钠-抗坏血酸-硫酸为底液组成,测量-430mV下锡的峰电流,并分析锡的质量浓度与峰电流的线性关系,进而测出矿石中的锡含量。这种方法快速、简便,且能避免高盐份影响测定仪器与结果,仅供参考。In order to quickly determine the tin content in the ore,an oscillopolarographic test was used.The composition was determined by using sodium chloride-ascorbic acid-sulfuric acid as the base liquid,and the peak current of tin at-430 mV was measured,and the linear relationship between the mass concentration of tin and the peak current was analyzed,and the tin content in the ore was measured.This method is fast and simple,and can avoid high salt affecting the instrument and results,for reference only.
