关于钛的比色剂,最长用的是双氧水和变色酸。在铬,镍含量高时双氧水法测定有困难,变色酸法要求严格不易采用。在分析耐热钢和不锈钢中之钛时,我們应用了抗坏血酸作试剂,得到了滿意的結果。仪器及試剂 1.71型高级光电比色计; 2.六用比色计PH部分,玻璃电极和甘汞电极。 3.钛标准溶液:取光譜纯的二氧化钛0.0799克,与1克焦硫酸钾共溶,熔融物用1%硫酸浸出,移入
About titanium colorimeters, the longest use of hydrogen peroxide and chromotropic acid. In the chromium, nickel content is high when the hydrogen peroxide method has difficulty in determining the requirements of the chromotropic acid is not easy to adopt strict. In the analysis of titanium in heat-resistant and stainless steels, we used ascorbic acid as a reagent and obtained satisfactory results. Instruments and Reagents 1.71 advanced photoelectric colorimeter; 2. Six with colorimeter PH part, glass electrode and calomel electrode. 3. Titanium standard solution: take the pure titanium dioxide 0.0799 g, co-dissolved with 1 g of potassium pyrosulfate, leach the melt with 1% sulfuric acid,
