- What is polyacrylamide grafted psyllium mucilage used for?
- Polyacrylamide grafted psyllium mucilage is used as flocculant for treatment in tannery and domestic wastewater, and is was also used for suspended solid removal from tanneries and other wastewater. The flocculation efficiency of the optimal dose of grafted mucilage showed pH for tanneries and domestic waste water respectively.
- How is psyllium mucilage obtained from plantagoovata?
- Kaith et al., observed psyllium mucilage which was obtained from plantagoovata hasbeen modified through graft copolymerization and network formation using acrylic acid (AA) as the monomer, potassium persulphate (KPS) as an initiator, and hexamethylenetetramine (HMTA) as a cross-linker [ 59 ].
- Can polyacrylic acid graft be used to make Mercury sorbent?
- Singh V. et al. (2010) studied, efficient mercury sorbent had been crafted by poly (acrylic acid) grafting onto C. javanica seed gum under microwave irradiation and synthesised graftcopolymer samples withvarying the reaction conditions of different %G .
- What is mulberry silk fiber graft copolymerized with?
- Banyal et al. reported that mulberry silk fiber was graft copolymerized with binary mixtures of acrylic acid, methyl acrylate and acrylonitrile with methyl methacrylate as the principal monomer in aqueous medium by using CAN as redox initiator.
