作者在测定矿石中微量钪的试验过程中,发现钛—过氧化氢—氯代磺酚S三元络合物可以应用于测定微量钛。这种三元络合物比钛—过氧化氢二元络合物的灵敏度高约30倍,比钛—氯代磺酚S二元络合物灵敏度高三分之一,比二安替比林甲烷钛灵敏度高约1倍。它的摩尔收光系数为2.22×10~4。但由于该法的选择性欠佳,铁、铜、锆、钪、钍等元素严重干扰测定,尤其是常见的铁、铜元素,因此,妨碍了其应用。但是,我们采用阴离子交换树脂分离了一系列干扰元素,成功地应用于金属铁、金属铝、金属钴及铝土矿中微量钛的测定,经与其它方法对照,结果较为满意。利用阴离子交换树脂分离后,有可能应用于金属钼、钨、铜、锌、镉、汞、镓、铟、铊、锗、锡、锑、砷、铋、铀、金、钌、锇、铱、钯、铂及化合物中微量钛的测定。
The author in the determination of trace scandium ore test process and found that titanium - hydrogen peroxide - chlorosulfonate S ternary complex can be used for the determination of trace titanium. This ternary complex is approximately 30 times more sensitive than the titanium-hydrogen peroxide binary complex and one-third more sensitive than the titanium-chlorosulfonated S binary complex, Lin methane titanium high sensitivity about 1 times. Its molar absorption coefficient is 2.22 × 10 ~ 4. However, due to the poor selectivity of the law, iron, copper, zirconium, scandium, thorium and other elements seriously interfere with the determination, especially the common iron and copper, thus hinder its application. However, we used anion exchange resin to separate a series of interference elements and successfully applied to the determination of trace titanium in metallic iron, metallic aluminum, metallic cobalt and bauxite. The results were satisfactory compared with other methods. After the separation by anion exchange resin, it is possible to apply it to metal molybdenum, tungsten, copper, zinc, cadmium, mercury, gallium, indium, thallium, germanium, tin, antimony, arsenic, bismuth, uranium, gold, ruthenium, osmium, Palladium, platinum and compounds Determination of trace titanium.
