A Rehological Screening Method for Membrane Modifying Polymers

Research output: Contribution to journalArticle

Abstract

A rheological method for screening water soluble polymers intended for fouling prevention of membranes is investigated.

Viscosity is measured of mixtures between polymers (neutral Dextran T500 positively charged DEAE-dextran and negatively charged dextran sulphate) and proteins (BSA, ovalbumin, pepsin and lysozyme).

The method is sensitive enough to detect interactions between the polymers and the proteins also at low concentrations.

Different types of interactions are discussed and one application with modified membranes is described (BSA and above mentioned polymers).
