Trace Elements Content of Mangium Pulp Throughout ECF Bleaching Stages as Measured by ICP

, 2015
The fate of metals in pulp of the five years old mangium wood (Acacia mangium Wild) during bleaching process was investigated. The wood was divided into tree division, i.e. bottom, middle and upper divisions.
