Preparation of modified polyacrylamide hydrogels and application in removal of Cu(II) ion Article in Polymer 42(18):7497-7502 · August 2001 with 147 Reads How we measure 'reads'
Preparation of modified polyacrylamide hydrogels and application in removal of Cu(II) ion Modified polyacrylamide hydrogels were prepared by transamidation and Hofmann reactions using different amine compounds. Products were characterized by their amine value (AV), equilibrium degree of swelling (EDS) and FT-IR spectroscopy.
Modified polyacrylamide hydrogels and their application
Modified polyacrylamide hydrogels and their application in removal of heavy metal ions. The metal ion removal capacities changed depending their BGC and EDS. While the Mannich products were selective towards Cu(II) ion, the sulfomethylation products were highly selective to Pb(II) ions. Modified polyacrylamide hydrogel. Heavy metal ion

- Which polymer is used to prepare acrylic acid hydrogel?
- Free radical polymerisation is commonly used to prepared acrylic acid hydrogel since acrylic acid can easily react with the electrophilic agent and free radicals . Acrylic acid (Fig. 1) is a monomer that is cross-linked to produce hydrogels with high water absorbing capacity as a single or multi-component system.
- What is polyacrylamide hydrogel (Paag)?
- 1. Introduction Polyacrylamide hydrogel (PAAG) is an extensively cross-linked polymeric hydrogel consisting of 2.5%–5% polyacrylamide and 95%–97.5% nonpyrogenic water.
- What is nonionic polyacrylamide?
- Nonionic polyacrylamides Nonionic polyacrylamides represent the smallest group of acrylamide-based polymers, representing about 25% of the total polyacrylamide market. Nonionic polyacrylamide is somewhat misleading since in the manufacture of acrylamide, regardless of the route, some degree of hydrolysis of acrylamide occurs.
- What is a high molecular weight nonionic polyacrylamide?
- High-molecular-weight nonionic polyacrylamides are routinely used in the mineral processing industries as thickeners and flocculants , , . 34.2.5. Polyacrylamide product forms The product types for polyacrylamides are solutions, liquids (emulsion or dispersion), and dry powders.
