Implication

Experimental analysis investigates citric acid's effect on alumina suspension properties, indicating potent stabilization potential.

Key Points

This study aims to characterize the interaction between citric acid and alumina in aqueous suspensions and evaluate its effect on stabilizing these suspensions.
Characterization of citric acid adsorption on alumina using adsorption isotherms and ATR-FTIR spectroscopy.
Measurement of electrophoretic mobility and rheological properties as a function of citric acid concentration and pH.
Construction of a stability map for alumina suspensions relating viscosity and dynamic measurements.
Maximum citric acid adsorption of 2.17 μ.mol/m² at pH 3, decreasing to 1.17 μmol/m² at pH 8.
Citrate adsorption shifts the isoelectric point of alumina to lower pH values, enabling control between pH 3 and 9.
Citrate creates a steric barrier that enhances suspension stability by preventing particle agglomeration.
