Novel nano cellulosic fibers for remediation of heavy metals from synthetic water
The increased surface area-to-volume ratio of nanoparticles, quantum size effects and the ability to tune surface properties through molecular modification make nanostructures ideal for environmental remediation. The present piece of work reports the preparation and characterization of nano cellulosic fibers (NCFs) with further polymeric reinforcement using vinyl sulphonic acid for the remediat...

متن کاملKey Considerations in the Determination of Polyelectrolyte Concentration by the Colloidal Titration Method
Medium or high charge density cationic polyelectrolytes are frequently used for water treatment. In the papermaking wet-end they are used as retention agents or as flocculating aids. Negative polyelectrolytes that enter the papermaking system increase the demand for cationic polyelectrolytes. Polyelectrolyte concentration can be determined by the colloidal titration method, using either of two ...
متن کاملComplex Formation between Bovine Serum Albumin and Strong Polyelectrolytes: Effect of Polymer Charge Density
Light scattering and pH titration were used to examine the binding of bovine serum albumin (BSA) to poly(diallyldimethylammonium chloride) (PDADMAC), poly(acrylamidomethylpropyl sulfonate) (PAMPS), poly(methacrylamidopropyltrimethylammonium chloride) (PMAPTAC), and an AMPS-acrylamide random copolymer (PAMPS80AAm20). The critical protein charge required to induce protein-polyelectrolyte complexa...
متن کاملCharge determination of proteins with polyelectrolyte titration.
A recently developed photometric version of polyelectrolyte titration was applied for the determination of the number of charged residues on globular proteins. Based on the observation that oppositely charged polyelectrolytes form, in general, stoichiometric polyelectrolyte complexes, the protein solutions were incubated in excess with an oppositely charged polyelectrolyte, and the residual amo...
