Polyelectrolyte

This study has investigated in a comparative fashion the effect of cations and polyelectrolytes on the characteristics and final properties of both synthetic and activated sludge. Synthetic sludge was prepared according to established procedures; activated sludge was produced in a lab-scale, continu

The removal of nitrate from contaminated groundwater via polyelectrolyte-enhanced ultrafiltration (UF) was investigated using different chelating polymers and membrane pore sizes. Although the percentage polymer rejection by membranes slightly decreased with higher chelating polyelectrolyte dosages,

Electrophoretic separations were theoretically performed for large polyelectrolytes such as DNA in the membrane chromatography. This paper deals with the study of the mass transfer involved in multi-layered membrane chromatography in the presence of an electric field. The different contributions to

Sulfonated poly(ether ether ketone) (SPEEK), a strong polyelectrolyte, was investigated as an additive in polysulfone (PSU)/SPEEK/N-methyl-2-pyrrolidinone (NMP) systems. Membrane characterisation was carried out using filtration studies and by atomic force microscopy (AFM). The effect of SPEEK in th
