A more eco-friendly synthesis of flocculants to treat

Using polymers with the other charge densities, 40 and 60%, the reduction of the water turbidity was lower, even if the polymers with 60% charge density did also show reasonable results. Apparently, for this effluent the synthesis medium does not seem to have a strong effect on the flocculant performance.

The intrinsic viscosity and positive charge density were achieved at 1577 mL g 鈭? and 4.43 mmol g 鈭? under different synthesis conditions, respectively. The chemical structure of polymer PDAC was confirmed via FTIR spectra, and 1 H NMR spectrum displayed the characteristic proton of different groups.

Abstract. The synthesis of cationic flocculants by inverse microemulsion copolymerization of acrylamide and [2- (acryloyloxy)ethyl]-trimethylammonium chloride in continuous reactors (single CSTR and two CSTRs in series) was investigated. It was found that the particular microstructure of the polymers strongly depended on the process.

Development of cationic flocculants from lignocellulosic wastes not only eliminates the health and environmental concerns associated with the use of conventional chemicals, but also is the way of waste valorization. In the present study, cellulose fibers extracted from rice husk were cationized through an optimization method based on response surface methodology. The fibers cationized at the
