碳纳米管与氨基酸作用的光散射性质研究

The Studies of Scatter Light Properties for the Interaction of the Amino Acid and the Carbon Nanotubes

研究了在乙醇中超声分散后的碳纳米管(CNT)与氨基酸相互作用的光散射性质。实验考察了激发波长,pH值,CNT浓度和水的百分含量对CNT光散射强度的影响;在优化的实验条件下,发现CNT与白氨酸作用时,CNT的散射强度会随着白氨酸的浓度的增加而增加,但是与天冬酰胺作用时,CNT的散射强度会随着天冬酰胺的浓度的增加而减弱,此方法有望用于对此二种氨基酸的实际分析测定。

The light scatter properties of the interaction between amino acid and Carbon nanotubes（CNT） in ethanol with supersonic were studied. The experiment conditions for light scatter intensity were optimized, such as the excited wavelength, pH, the concentration of CNT and the percent of water. In the optimal conditions, when the CNT acts with leucine, the scatter light intensity of CNT enhances with the increase of the concentration of leucine. But when the CNT acts with asparamide, the scatter light intensity of CNT decreases with the increase of the concentration of asparamide. The method was used for the analysis and determination of amino acid.
