    Sammanfattning : The purpose of this study was to investigate the fundamental characteristics of a chelating surfactant in terms of solution behaviour, chelation of divalent metal ions, and interaction in mixtures with different foaming agents and divalent metal ion, as well as examining its prospects in some practical applications. Chelating surfactants are functional molecules, with both surface active and chelating properties, which are water soluble and therefore suitable for chelation in many aqueous environments. LÄS MER

  3. 2. Structural impact on some physical properties of cellulose-based films

    Sammanfattning : Cellulose is a natural material that can be used both in its original form and as a building block for creating new types of materials. This work focused on regenerated cellulose (RC) and cellulose acetate butyrate (CAB) in which the hydroxyls on the cellulose backbone were substituted with ester groups. LÄS MER
