曾研究钛-二安替比林甲烷-二氯化锡二元络合物萃取光度法测定钛。我们试验增加二安替比林甲烷浓度,加速了反应,几分钟便可显色完全。可用于高纯铁和钢中微量钛(10~(-2)—10~(-4)%)的快速、准确的光度法测定。一试剂钛标准液 (a)100μg Ti ml~(-1),称取纯二氧化钛0.1668克。放入垫有5克碳酸钠-硼砂(2+1)熔剂的铂坩埚中,混匀,再盖2克熔剂,在950°～1000℃马弗炉中熔融15分钟。冷却,用300毫升盐酸(1+2)浸取,于量瓶中稀释至1升。
Extraction of Titanium with Diantipyrine Methane - Tin Dichloride Binary Complex by Spectrophotometry. We experimented with increasing the concentration of diamipinine methane to accelerate the reaction and to develop color in a matter of minutes. It can be used for the rapid and accurate spectrophotometric determination of trace titanium (10 ~ (-2) -10 ~ (-4)%) in high purity iron and steel. A reagent titanium standard solution (a) 100μg Ti ml ~ (-1), weighed 0.1668 grams of pure titanium dioxide. Placed in a platinum crucible with 5 g of sodium carbonate-borax (2 + 1) flux, mixed, covered with 2 g of flux and melted in a muffle furnace at 950-1000 ° C for 15 minutes. Cool, leach with 300 ml of hydrochloric acid (1 + 2) and dilute to 1 liter in a measuring flask.
