A super-efficient polyquaternium gel that can remove over-10-times masses of lignins from wastewater for resourcefulness

Abstract To address the efficient resourcefulness of papermaking wastewater, this study designed a super-efficient gel material (SGPQG/SGPQ) that could remove over-10-times masses lignins from and subsequently realized highly-efficient reuse wastes. The mass lignin removed by per unit SGPQG/SGPQ was 10,157.71 mg•g -1 , i.e., 10.16 times itself, which 1.23-50.55 better than existing similar materials, showing removal ability. Meanwhile, average rate 1.85-3.34 higher those pre-products. Moreover, extended application in purification complex wastewater real had been also successfully carried out. mechanism investigations confirmed an integrated skeleton-space effect mechanism, is key factor for to achieve wastewater. In addition, wastes after treating lignins, be directly used adsorption treatment dyeing 443.9 capacity compared widely-used activated carbon, demonstrating reuse.
