Abstract:

The aim of this study was to investigate the kinetics of adsorption of mucin onto titanium surface. Mucin adsorbed onto untreated, calcium and potassium treated titanium surfaces in vitro tests were monitored using uv-visible spectrophotometer the effect of contact time was determined by the ‘’limited bath technique.’’ The parameters used in this study such as 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, 350C and 6.4, respectively. The amount of mucin adsorbed increased with time until equilibrium was attained after about 115 min 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 Ca˛ 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.
