Description
It was shown that the isolation and the purification of alkali lignin could be carried out by the treatments of their black liquors with the ion exchange resins.
The experimental data concerning on the yield of the lignins isolated and on the residual natrium contents after elimination of Na included in the soda process lignins and the thiolignins treated by the ion exchange resin the Amberlite-IR-120, were compared with the results by pH3-sulphuric acid process.
Concluding from these results, the ion exchange resin treatment method can be applied under the moderate conditions and in the good yields for these purposes.
