【摘要】 针对含铜试料中锡的快速测定，提出用KSCN－KI混合掩蔽，对于不同掩蔽剂的作用、干扰元素、溶解氧、酸度的影响、还原剂选择及蒋样方式等多方面进行了试验，获得较好效果。更多还原

【Abstract】 Good results of the repid determinationn of tin in copper -- bearing samples with iodimetry are attained. KSCN -- KI is used as masking agent. Experiments on the function of different masking agents; effects of interfering elements,diedved oxygen and acidity; and sele of reductants and methods for melting sample are performed.更多还原
