摘　　要：本论文主要介绍了用光度分析测定锡矿石中锡含量的具体操作过程及结果分析。光度法测定低量锡是目前国内外一种广泛应用的方法。在测定锡矿石中锡含量时,重量法、滴定法等化学分析方法手续繁琐、操作严格,而光度法则具有灵敏度高、选择性好,测定下限低,简便、快速,准确度高等优点。可用于日常生产分析。This paper mainly introduces the specific operation process and result analysis of spectrophotometric determination of tin content in tin ore.Spectrophotometry is a widely used method for the determination of low tin content at home and abroad.In the determination of tin content in tin ore,the chemical analysis methods such as gratometry and titration are complicated and strict,but the photometric method has the advantages of high sensitivity,good selectivity,low determination limit,simple,rapid and high accuracy.Can be used for daily production analysis.
