摘要
海水珍珠贝肉所含的17种氨基酸可诱导合成碳酸钙结晶体,但合成温度和不同氨基酸的比例会影响其结晶形貌。本研究利用贝肉中所含的17种氨基酸,构建不同的温度和氨基酸比例体系,对碳酸钙晶体进行仿生合成,试图找出影响碳酸钙结晶形貌的主要因素,为进一步仿生合成探索有效途径。利用扫描电子显微镜(SEM)、红外光谱(FT-IR)、X射线衍射(XRD)对实验结果进行表征,结果表明,不同反应温度、不同氨基酸含量可以调控碳酸钙形貌与成分,等体积氨基酸混合、50℃条件为本研究条件下制备类珍珠层的最适实验方案。
The seventeen types of amino acids contained in seawater pearl shellfish can induce the synthesis of calcium carbonate crystals, but the synthesis temperature and the ratio of different amino acids will affect the morphology of the crystals. In this study, seventeen kinds of amino acids contained in shellfish were used to construct different systems with varied temperatures and amino acid proportions. These systems were aimed to conduct bionic synthesis of calcium carbonate crystals. The main factors that influence the crystal morphology of calcium carbonate were found out. Then, an effective way for further bionic synthesis could be found. The experiments were conducted by scanning electron microscopy ( SEM), infrared spectroscopy ( FT-IR) and X-ray diffraction ( XRD). The research results showed that different reaction temperatures and amino acids could regulate the morphology and composition of calcium carbonate.Amino acid mixture volume, for example, 50 ℃ was the optimal experiment scheme for the preparation of pearl layerin this study.
