“…The development in modern medical science has improved biomaterials role in replacing damaged tissue, organs, and improving their functions. Hydroxyapatite (HAP) one of the apatite minerals with a chemical formula of (Ca 10 (PO 4 ) 6 (OH) 2 ), is a major inorganic constituent about 60-70 % of the inorganic portion of the bone matrix and possesses the high ability of ion-exchange against various cations which make that HAP has high biocompatibility and bioactivity properties [7][8][9][10]. Besides HAP can be used in a wide range of applications such as bone substitution, fertilizers, food supplements as a source of calcium, dental materials, drug delivery agent, gene carriers biology, adsorbent of liquid chromatography and proteins, catalysts, ion exchangers, removal of organic pollutants like phenol and other divalent metal cations, gas sensors, proton conductors and more [4,5].…”

“…HAP has been reported to exhibit excellent biocompatibility, bone-bonding ability and also possesses no toxicity or inflammatory response towards the human body [2]. Due to these beneficial attributes, it has widely been investigated within biomedical applications such as a bone/teeth implants, bone tissue regeneration, cell proliferation and drug delivery [3,4]. In addition to these applications, the specific characteristics of HAP, such as low water solubility and high stability under oxidising and reducing conditions, make this material suitable as a sorbent in the purification of wastewater and removal of a variety of heavy metals, such as arsenic (III), selenium (IV), lead (II), cadmium (II), cobalt (II) or nickel (II) from contaminated industrial aqueous waste [5][6][7][8][9].…”

Abstract:A novel procedure for the synthesis of both hydroxyapatite (HAP) and palladium doped HAP via a wet chemical precipitation method is described herein. X-ray Diffraction (XRD), Raman Spectroscopy, Scanning Electron Microscopy (SEM) with Energy Dispersive X-ray Spectroscopy (EDS) and Fourier Transform Infrared (FT-IR) Spectroscopy are utilised to characterise the synthesised material's morphology, structure and crystallinity. The developed synthetic protocol produces high purity HAP with an average yield of 83.7 (˘0.10)% and an average particle size of 58.2 (˘0.98) nm, such synthesis has been achieved at room temperature and within a time period of less than 24 h. Additionally, in order to enhance the overall conductivity of the material, a range of Pd (2, 4 and 6 wt %) metal doped HAP has been synthesised, characterised and, for the first time, applied towards the competitive electrocatalytic detection of hydrazine, exhibiting a linear range of 50-400 µM with a limit of detection (3σ) of 30 µM.

Abstrak: Hidroksiapatit dengan struktur heksagonal merupakan biomaterial yang berpotensi sebagai implan tulang maupun gigi, karena memiliki sifat biokompatibilitas, dan bioresorbabilitas. Karakteristik kimia dan kristalinitas hidroksiapatit yang mirip dengan sifat tulang dan gigi manusia, menyebabkan kehadirannya dalam tubuh mudah diterima. Tujuan penelitian ini untuk menyintesis hidroksiapatit dengan metode basah menggunakan kalsium hasil isolasi dari cangkang telur ayam. Sintesis hidroksiapatit dilakukan dengan reaksi metode basah. Proses sintering optimum diamati dengan variasi waktu 3, 5 dan 9 jam. Karakterisasi struktur, morfologi, dan komposisi unsur hidroksiapatit masing-masing menggunakan XRD dan TM-EDX. Hidroksiapatit terbanyak diperoleh pada waktu sintering selama 5 jam, yaitu sebesar 74,74%, dengan rasio massa Ca/P 1,67. Pola difraksi XRD hidroksiapatit hasil sintesis mirip dengan ICSD #157481.Kata kunci: biomaterial, cangkang telur, hidroksiapatit, metode basah Abstract: Hydroxyapatite with hexagonal structure is a potential biomaterial as bone and dental implants, because it has the nature of biocompatibility, and bioresorbability. Characteristics and crystallinity of hydroxyapatite are similar to those of human bones and teeth, that why its presence in the body is readily acceptable. The aim of this research is to synthesize hydroxyapatite by wet method using calcium isolated from
