Study and application of determination of different content level iron by sulfosalicylic acid differential spectroscopy 磺基水楊酸差示分光光度法測定不同含量鐵的研究及應(yīng)用
After improving , the effect of the beam splitter is removed , all the data measured can be compared together . the digital spectrum data is convenient for the implementation of the differential spectroscopy 改進后的歸一化方法消除了分光鏡的影響,每次測量的數(shù)據(jù)具有可比性,實現(xiàn)了光譜數(shù)據(jù)的數(shù)字化,為導(dǎo)數(shù)光聲光譜技術(shù)的實現(xiàn)準備條件。
