Studies of the Alumina Suspension Stability in the Presence of Anionic Polymer—Influences of Polymer Molecular Weight, its Concentration and Solution pH

The effect of an anionic polymer—polyacrylic acid (PAA) adsorption on the alumina (Al2O3) suspension stability was studied. The influence of the following parameters was examined: polymer molecular weight, its concentration and solution pH. Two methods were used to monitoring the suspension stability: turbidimetry and spectrophotometry. The conformational changes of macromolecules, both adsorbed and non-adsorbed, determine the stabilization—flocculation properties of the alumina suspension in the presence of the polymer.
