Abstract
The kinetics of adsorption of mucin onto titanium surface was investigated. The amount of
titanium, concentration of mucin solution, reaction temperature and pH were optimised by
preliminary experiments as 0.02 mg, 0.1 mg/ml, 35 °C and 6.4, respectively. The amount of
mucin adsorbed increased with time until equilibrium was attained after about 115 minutes
with the maximum concentration of mucin adsorbed being 0.0603 mg/ml for Ca-Ti followed
by that of unto K-Ti implying that the adsorption is not influenced by the presence of Ca²
ions. Analysis of kinetic data obtained with Lagergren, Bhattacharya/Venkobacharya and
Flick’s models revealed that the adsorption is first order with respect to mucin molecules and
that diffusion is the predominant mechanism for the adsorption.
