Abstract Iron, cobalt, copper and zinc decorated hydroxyapatite nanoparticles were produced with using ultrasonically assisted wet chemical method. Calcium nitrate tetra hydrate and dibasic ammonium phosphate were used as calcium and phosphorous source, respectively. Calcium nitrate tetra hydrate and dibasic ammonium phosphate solutions were prepared by dissolving the salts in distilled water and at different concentrations of decorated elements (iron, cobalt, copper and zinc) were appended to the calcium nitrate tetra hydrate solution. Stoichiometric decorated hydroxyapatite nanoparticles were analysed by energy dispersive X-ray fluorescence (EDXRF) with using standard method and the element analysis was determined with looking at the grain structures by Energy Dispersive X-Ray (EDX) and scanning electron microscopy (SEM). Not only have the concentrations of decorated metals but also calcium and phosphorus ratio for artificial bone powders been determined. As a result, calcium and phosphor ratio and metal decorated contents were evaluated according to the production values and compared previous studies. The answer to the question of how much of the contribution amounts was searched.

通过 EDXRF 和 SEM 对铁、钴、铜和锌装饰的羟基磷灰石合成骨粉进行元素分析

摘要 采用超声辅助湿化学法制备了铁、钴、铜和锌修饰的羟基磷灰石纳米粒子。四水合硝酸钙和磷酸氢二铵分别用作钙源和磷源。四水合硝酸钙和磷酸氢二铵溶液是通过将盐溶解在蒸馏水中制备的，并将不同浓度的装饰元素（铁、钴、铜和锌）添加到四水合硝酸钙溶液中。使用标准方法通过能量色散 X 射线荧光 (EDXRF) 分析化学计量装饰的羟基磷灰石纳米粒子，并通过能量色散 X 射线 (EDX) 和扫描电子显微镜 (SEM) 观察晶粒结构来确定元素分析。不仅测定了装饰金属的浓度，还测定了人造骨粉的钙磷比例。因此，根据产值评估钙磷比例和金属装饰含量，并比较以前的研究。搜索了多少捐款金额的问题的答案。
