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

Dissolvine remove or deactivate metal ions in pulp bleaching

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.
