超分散剂在莠去津颗粒表面吸附的红外和拉曼光谱学研究

摘要

聚羧酸型梳状共聚物超分散剂在农药环保剂型悬浮剂的研究中起着重要的作用,可使其理化稳定件得到明显改善,因此研究聚羧酸型梳状共聚物超分散剂在莠去津颗粒表『疗i的吸附行为具有重要的理论和实际意义.利用傅里叶红外光谱(FTIR)和傅里叶拉曼光谱(FT-Raiman)对超分散剂在莠上津表面的吸附行为进行了光谱学表征,结果表明,氢键足超分散剂分子与莠上津表面结合的主要作用力,是分散剂分子在莠去津表面吸附的重要推动力.但分散剂分子在莠去津表面究竟吸附多少和吸附厚度多大才能使悬浮体系得到稳定,还需进一步采用光谱学表征手段进行定量分析加以确认.本文研究结果为开发稳定的莠上津悬浮剂和光谱学定量分析奠定理论基础,为莠去津悬浮剂的应用提供了重要的信息.%The main methods in performing the study of the adsorption properties of hyperdispersant on atrazine surface were fourier transform infrared spectroscopy(FTIR) and FT-Raman spectrometer (FT-Raman), and the results suggested that the hydrogen bond force was the main force combining the surface of atrazine particles and the dispersant. And it also promoted the adsorption of dispersant on atrazine particles. However, the information of what accurate quantity of the dispersant adsorbed on the surface of atrazine should a successful suspension ability of the suspension concentrate acquire is still not available. And researches on this question still need to be done with the help of quantized spectroscopy method. The result of this study provided a theoretical foundation for the development of stable atrazine suspension concentrate and the spectroscopy quantitative analysis of it. This result provided significant information for the application of atrazine suspension concentrate at the same time.
