    • Preliminary study on the stannous ions removal from aqueous solutions by hydroxyapatite 

      Sri Asliza, Md Amin; Mohd Zaheruddin, Kasmuin; Kamrosni, Abdul Razak (Universiti Malaysia Perlis (UniMAP), 2012-07-18)
      The effect of stirring times and pH of solutions on the potential of HA in removing Sn ions have been investigated. The results shown that HA powder have tendency to remove a number of Sn ions by adsorption mechanisms. The ...

    • Preparation and characterization of natural Hydroxyapatite from bovine bone 

      Shahrizal, M. H.; Sri Asliza, Md Amin; Mohd Nazree, Derman; Mohd Zaheruddin, Kasmuin (Universiti Sains Malaysia (USM), 2008-06-18)
      The purpose of this study was to prepare and characterize Hydroxyapatite from natural source. Hydroxyapatite fine powder with average size particle of 10.324 um had been prepared by heating bovine bone at temperature 800°C ...

    • Response of functionality graded hydroxyapatite/F-75 in saline solution 0.9% NaCl 

      Noorazimah, Mohd Ab Llah; Shamsul Baharin,  Jamaludin, Prof. Dr.; Nur Hidayah, Ahmad Zaidi (Trans Tech Publications, 2013)
      Functionally graded hydroxyapatite (HAP) /F-75 was fabricated using powder metallurgy technique. Samples fabricated were tested inside 0.9% NaCl to check their bioactivity reaction. After immersed, samples were analyzed ...

    • Study the effect of TIO2 and soaking time to the natural hydroxyapatite properties
