Efficient Removal of Anionic and Cationic Dyes from an Aqueous Solution Using Pullulan-graft-Polyacrylamide Porous Hydrogel
In addition, FTIR spectral analyses were performed to confirm the graft polymerization of acrylamide onto pullulan to synthesis the pullulan-graft-polyacrylamide porous hydrogel. As shown in Fig. 1 , the infrared spectrum of the pullulan and hyd
An anionic, low-cost, and environmentally friendly composite PVA/Agar/Bentonite (PAB) hydrogel was prepared via self-assembly method, then evaluated as an adsorbent for both cationic methylene blue (MB) and anionic Congo red (CR) dyes using

- Can silica nanoparticles improve rheological properties of partially hydrolyzed polyacrylamide?
- This work aims to improve the rheological properties of partially hydrolyzed polyacrylamide (HPAM) for enhanced oil recovery by using silica (or silicon dioxide, SiO2) nanoparticles (NPs). Novel aq...
- What is partially hydrolyzed polyacrylamide (PHPA)?
- Partially hydrolyzed polyacrylamide (PHPA), consisting of neutral acrylamide and anionic acrylate groups, is suitable for use in water with <25,000 mg/L TDS 12, 15.
- Which polymer is used to produce partially hydrolyzed polyacrylamide (HPAM)?
- PAM is used to produce partially hydrolyzed polyacrylamide (HPAM), which is linear, anionic, water-soluble, stable, polymeric, and high molecular weight chain of acrylamide (C 3 H 5 NO) monomers (Bao et al., 2010; Braun et al., 2025; Liu et al., 2016; Xiong et al., 2018).
