GB/T 10338-2008 "Determination of Carboxyl Content in Pulp" specifies the use of calcium ion exchange and EDTA volumetric method to determine the carboxyl content in pulp, applicable to various types of pulp such as chemical pulp, mechanical pulp, and semi-chemical pulp. The standard clarifies the determination principle, reaction formulas, and operational procedures, and includes additions such as quality assurance and control, as well as test reports. Through standardized chemical analysis processes, it accurately quantifies the carboxyl content in pulp, providing data support for evaluating pulp performance and optimizing papermaking processes.
