Preparation and Application of Modified Sodium Lignosulfonate Hydrogel

Lignosulfonate have a tri-dimensional network like structure containing hydroxyl,carboxyl and sulphonyl groups in their molecules, these structural features therotically ensured them to be a good raw material for preparing the hydrogel. This paper focuses on the development and utilization of lignosulfonate. Firstly, we studied the preparation of lignosulfonate hydrogel, made an investigation into the removal […]
