Determination of sodium, calcium, copper, iron and manganese in pulp and paper by atomic absorption spectroscopy

This method describes the determination of sodium, calcium, copper, iron, and manganese in pulp, paper, and wood by atomic absorption spectroscopy.

This method may also be applicable to other elements, provided that they do not volatilize in the process.

For alternate procedures see these methods which have been reclassified as Classical Methods: TAPPI T 241 “Manganese in Pulp,” TAPPI T 242 “Iron in Pulp,” TAPPI T 243 “Copper in Pulp,” TAPPI T 247 “Calcium in Pulp,” and TAPPI T 623 “Sodium Determination by the Uranyl Zinc Acetate Method.” A modern alternative method used by many analytical laboratories is inductively coupled plasma atomic emission spectroscopy (ICP-AES).
