  • Nonionic Polyacrylamide Available Top Quality at Best

    2019-9-9 · However, production of nanoscaled cellulose such as cellulose nanocrystalline and cellulose nanofibril usually requires harsh condition (Blanco et al. 2018), and it often consumes large amount of mineral acid in the case of cellulose nanocrystalline while the yield is not satisfactory (Chen et al. 2016). Therefore, direct application of a nanoscaled cellulose as flocculant may still be challenging, on consideration of the relatively high cost of the nanoscaled cellulose …
