摘要：
The spectrophotometric methods for the determination of lignin substances in water are evaluated and modified. Covered are the tungsten-molybdate-phosphate and nitrate methods for the visible spectrum region, and the Goldschmid's and Lindberg's methods, as well as the orientation method of the absorbency observation at 280 nm for the UV-spectrum region.
