文摘内容 The measurement of lignin content in black liquid of straw AS-AQ by ultraviolet spectrophotometer (UV) is discussed in this paper. Different dilution multiple and contrast solutions have an effect on the measured results of the lignin content by UV. The calculation method for the absorption coefficient and thes canning spectrum property of liquor acidified by SO are introduced in this paper。
