The Influence of Mellitic Acid on the Crystal Growth of Hydroxyapatite

  • Zahid Amjad


The constant composition method has been used to study the influence of mellitic acid (benzene hexacarboxylic acid) on the kinetics of crystal growth of hydroxyapatite (HAP) at low constant supersaturation. Addition of mellitic acid to the calcium phosphate supersaturated solutions has a striking inhibitory influence upon the rate of crystal growth of HAP. The effect is interpreted in terms of adsorption, following the Langmuir isotherm, of mellitate ions at the active crystal growth sites.
