GB/T 10337-2008 "Determination of Acid-Soluble Lignin in Raw Materials and Pulps for Papermaking" specifies the method for determining acid-soluble lignin in raw materials and pulps for papermaking, applicable to various types of raw materials and pulps. Based on the solubility characteristics of acid-soluble lignin in sulfuric acid solution, the absorbance is measured at a wavelength of 205 nm using an ultraviolet spectrophotometer, and the mass percentage of acid-soluble lignin is calculated using a formula. The standard has revised the content of reagents and experimental procedures and added warning prompts to ensure the accuracy and safety of detection.
