摘要
采用2.5次微分催化极谱法,在硫酸—硫酸羟胺—硫酸钠—抗坏血酸—碲(Ⅳ)混合底液中,在国产JP3-1型极谱仪上,于起始电位-0.700伏,终止电位-1.200伏,测定矿石中微量铼。铼浓度在0—15μg/25m l可保持线性关系,且灵敏度高,重现性好,完全满足钼矿、辉钼矿中,以及其他矿物中微量铼的测定。
By the quardratic,pentad differentiation catalysis polarographic method,in the mixed base solution of sulphuric acid-hydroxylamine sulfate-sodium sulfate-ascorbic acid-Te,with the polarograph instrument Jp3-1 type made in China,start potential 0.700 V,end potential 1.200 V,the trace Re in ore is determined,which can keep the linear relationship as the Re concentration 0～15 μg/ml,sensitivity high,repeatability good,and completely meet the requirement of the determination of trace Re in Mo ore,molybdenite and other minerals.
