鸟粪石（Ammonium MgPO 4. 6（H2O））是一种很有研究价值的无机磷酸盐矿物。鸟粪石是泌尿系结石的成分之一。鸟粪石在尿液中以微晶形式出现，并作为一种肾结石生长。本研究采用湿化学法合成鸟粪石纳米粒子。含有溶解的Mg（CH 3COO）2·4 H2O和（NH 4）H2 PO 4的水溶液以Mg/P摩尔比为1.00混合。采用XRD、FT-IR、热分析、TEM等手段对合成的鸟粪石纳米粒子进行了表征。从XRD，发现纳米颗粒的晶体结构是正交的，并且发现晶体尺寸在11至26 nm之间。 鸟粪石纳米颗粒的FT-IR光谱证实了水分子和金属-氧伸缩振动、O-H伸缩和弯曲、N-H弯曲和伸缩、P-O弯曲和伸缩振动的存在。热分析在室温至900°C下进行。通过TEM分析，…
Struvite, Ammonium Magnesium Phosphate Hexahydrate [(AMPH) - (NH4)MgPO4.6(H2O)], is one of the fascinating inorganic phosphate minerals. Struvite is one of the components of the urinary stones. Struvite occurs as crystallites in urine and grows as a type of kidney stone. In this study, struvite nano particles were synthesized by wet chemical technique. The aqueous solutions containing dissolved Mg(CH3COO)2.4H2O and (NH4)H2PO4 mixed at the Mg/P molar ratio of 1.00. The synthesized struvite nano particles were characterized by XRD, FT-IR, Thermal Analysis and TEM. From XRD, crystal structure of the nano particle was found to be orthorhombic and crystalline size was found to be within 11 to 26 nm. The FT-IR spectrum for the struvite nano particles confirmed the presence of a water molecule and metal-oxygen stretching vibration, O-H stretching and bending, N-H bending and stretching, P-O bending and stretching vibrations. The Thermal Analysis was carried out from room temperature to 900°C. From TEM analysis, ...
