Mechanism for the adsorption of mucin on hydroxyapatite

Abstract

The adsorption of mucin onto HA has been investigated with respect to the role of electrostatic interactions, ionic environment, mucin concentration and pH. Aqueous solution of Mucin was suspended with treated and untreated HA and the mucin concentration in the supernatant determined. The Langmuir's model was used to analyze isotherm data; the maximum amount of mucin adsorbed and the affinity or association constants were calculated. The presence of added Ca ions increased the amount of mucin adsorbed as well as the association constant.
