Effect of Citrate on Morphological and Structural Properties of Hydroxyapatite Nanoparticles Synthesized by Wet Chemical Precipitation Method
Hydroxyapatite (HAp) nanoparticles organically modified with citrate group are fabricated via a simple wet chemical precipitation method. The as-synthesized nanoparticles are structurally characterized by TEM, XRD, FT-IR, EDAX and dynamic light scattering (DLS) to investigate in detail the influence of surface coating ligand i.e. citrate on HAp morphology, crystal structure, phase and colloidal stability of the particles. Production of single phase with hexagonal crystal structure is evident by XRD analysis. The work shows mesoporous structure could be synthesized under the influence of citrate as confirmed by TEM image and N2 adsorption−desorption isotherm. The experimental results indicate that citrate strongly influences HAp crystallization giving reduced particle size and uniform distribution. BET and BJH analysis indicate large surface area 135.74 m2/g and pore diameter of 9.86 nm with a total pore volume of 0.41 cm3/g respectively for 1 : 1 citrate to calcium ion molar ratio. The appropriate surface area and pore entrance significantly indicate potentiality to apply into biomedical fields as drug loading/delivery application.
期刊介绍：
Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
