资料介绍了钛—二安替比林甲烷—氯化亚锡三元络合物萃取分光光度法测定微量钛时,镍、钴、铬、钼、钒、铌等元素均不干扰.本文应用此法着重对可伐合金中微量钛的测定进行了试验.方法灵敏度高、简便可靠,可用于测定可伐合金、镍锰钢、低合金钢、铝镍钴铜合金中微量钛(≥0.002%).一、分析步骤称取0.250克试样于150毫升锥形瓶中,以20毫升硝酸(1+3)溶解,滴加2～3毫升盐酸,加5毫升硫酸(1+1)加热蒸
This paper introduces the extraction and determination of trace titanium by Ti-Diantipiron methane-stannous chloride ternary complex by spectrophotometry, without any interference of nickel, cobalt, chromium, molybdenum, vanadium, niobium and other elements.In this paper, The method focuses on the determination of trace titanium in Kovar.METHODS The method is sensitive, simple and reliable and can be used for the determination of trace titanium (≥0.002%) in Kovar, nickel-manganese steel, low-alloy steel and Al-Ni- First, the analysis step Weigh 0.250 g sample in 150 ml Erlenmeyer flask, dissolved in 20 ml of nitric acid (1 +3), add 2-3 ml of hydrochloric acid, add 5 ml of sulfuric acid (1 + 1) heating steam
