摘要
以H2SO4-K2SO4分解样品,加入少量(NH4)2MO4O13.2H2O加速样品还原,采用次甲基蓝-甲基橙作指示剂,Ce(SO4)2标准溶液作滴定剂,实现了锑矿石中锑的快速测定,此法分析速度快,RSD小于3%,测定值与标准样品推荐值比较,结果吻合。
Abstract ： By H2SO4 - K2SO4 decomposition sample, joins （NH4） 2MO4O13 · 2H2O acceleration sample to return to original state few, uses the ethylene blue-methyl orange to make the indicator, Ce （ SO4 ）2 standard solutions makes the titrant, has realized in the stibium ore the stibium fast determination, this law analysis speed is quick, RSD is smaller than 3% , the determination value and the standard sample recommendation value compares, finally tallies.
