随着钛及钛白粉的广泛应用,中外各厂家对其质量的要求也越来越高,因此,对二氧化钛中杂质元素进行测定更具有实际意义.我们采用直接装样的粉末光谱法试验了二氧化钛中铁、镍、钒、镁、铝、硅、钴、铬、钼、锰、铅、锡、铜等杂质元素测定时混合缓冲剂的作用,上下电极形状对谱线黑度的影响.方法的测定灵敏度为1×10~(-5)～3×10~(-4)%,相对标准偏差为10.7～21.4%.
With the wide application of titanium and titanium dioxide, the requirements of foreign and domestic manufacturers for their quality are also getting higher and higher, therefore, the determination of impurity elements in titanium dioxide is more practical.We used direct loading sample powder spectroscopy to test the titanium dioxide Effect of Mixed Buffer on Determination of Impurity Elements in Iron, Nickel, Vanadium, Magnesium, Aluminum, Silicon, Cobalt, Chromium, Molybdenum, Manganese, Lead, Tin, Copper and the Influence of Upper and Lower Electrode Shape on Spectral Blackness. The sensitivity is 1 × 10 ~ (-5) ~ 3 × 10 ~ (-4)%, the relative standard deviation is 10.7 ~ 21.4%.
