摘要
本文通过对水中挥发酚和油类测定中干扰因素的讨论 ,提出了酚测定时预蒸馏中问题的解决和空白样吸光度降低的方法 ,同时分析了油测定中溶剂的选择 ,及 H2 SO4、Na Cl、无水 Na2
Through the discussion of interference factors in determination of volatile phenol and oil in water, the paper gives the methods to solve the problem in predistillation and lower blank absorbability, analyses the influence solvent choice and the use of H 2SO 4、NaCl and anhydrous Na 2SO 4 as well as extractive liquor treatment in oil determination.
