摘要
试验了用氯代磺酚S在水相显色测定微量钪,具有易掌握、试剂易得、成本低、重现性好、相对误差不大于20%,回收率在94%以上,克分子消光系数为1.8×10~4等特点,并成功地应用在钒钛磁铁矿、金红石、铁粉、黑钨渣中微量钪的测定。也适用于其它复杂矿物中微量钪的测定。
The microamount of scandiun in vanadous titanomagnetite was determined using the color development reaction of chlorosulphonphenol S in aqueous phases. This method is characterized by ease of operation, availability of the reagent, low cost and good reproductivity. The relative error of this analysis is less than 20%, standard recovery≥94%, molar extinction coefficient 1.8×10~4. This method has been successfully used for determining the microamounts of Sc in rutile, iron powder and slag from wolframite treatment besides Sc in the magnetite, and allows the determination of microamounts of Sc in other complex minerals.
