Remove or deactivate metal ions in pulp bleaching

Dissolvine® chelating agents are used to remove and deactivate metal ions in pulp bleaching processes.

Some transition metal ions catalyze the decomposition of bleaching agents – peroxide, ozone and hydrosulfite – and can lead to brightness reversion of pulp and paper.

Dissolvine chelating agents are used to remove and deactivate these heavy metal ions, which result in a more efficient and low cost bleaching operation.
