磺基水杨酸光度法连续测定岩石中的铁和钛
CONTINUOUS SPECTROPHOTOMETRIC DETERMINATION OF IRON AND TITANIUM IN ROCKS WITH SULPHOSALICYLIC ACID
【摘要】 本文提出用磺基水杨酸(SSA)作显色剂,在不同pH值和同一波长下.于一分试液中连续测定铁和钛的分析方法。测定波长为420nm,测铁的pH值为8—11,Fe量在0—10μg/ml范围内服从比尔定律;测钛的pH值为2,TiO2量在0—14μg/ml范围内服从比尔定律。
【Abstract】 In this paper,the method of continuous determination iron and titanium with sulphosalicylic acid colour reaction in the same solution and different pH at same wavelength has been investigated. Determinating condition for iron is λ=420nm,pH=8-11 and Fe content in the range 0-10μg/ml obeying Beer’s law, Determinating condition for titanium is =420 nm.pH = 2 and TiO2 content in the range 0-14μg/ml obeying Beer’s law.
