【摘要】 以水溶液作为生物模拟体系,在不同反应摩尔比条件下,合成了一系列胆红素钙,利用中、远红外光谱,多晶X射线粉末衍射谱,电感耦合等离子体发射光谱等对合成的胆红素钙进行了表征.结果表明:胆红素钙的组成在Ca(C33H34N4O6)和Ca2.4(C33H32N4O6)(H2O)0.06之间变化,具有非化学计量性质,显示了与生物矿化产物相类似的特征.不同的胆红素钙其配位情况有所不同,并且钙含量较高时形成的胆红素钙有较好的结晶态.更多还原

【Abstract】 Different molar ratios of calcium chloride to sodium bilirubin were mixed to form a series of calcium bilirubinate in aqueous solution. The calcium bilirubinate was characterized by fourier transform infrared, powder X-ray diffraction, and inductively coupled plasma atomic emission spectrometry. The results showed that composition of calcium bilirubinate changed between Ca(C₃₃H₃₄N₄O₆)and Ca_2.4(C₃₃H₃₂N₄O₆)（H₂O）_0.06. There were different coordination states in the complexes of calcium bilirubinate. The complexes with more calcium crystallized well in the experimental condition.更多还原
