High-performance liquid chromatography (HPLC) is a commonly used technique for separating chiral compounds. Chiral stationary phases (CSPs) is a crucial factor that determines the resolution of chiral compounds. Therefore, developing new CSPs with better performance is highly desired. Carbon nanotubes (CNTs) is a promising material that has been widely used as a support for different CSPs. In this study, we aim to synthesize CSPs based on MWNTs-starch derivatives and evaluate their performance for HPLC separation of chiral compounds.Objectives:1. Synthesize MWNTs-starch derivatives as chiral stationary phases (CSPs).2. Evaluate the performance of CSPs using HPLC to separate chiral compounds.3. Optimize the separation conditions for the MWNTs-starch derivative-based CSPs.4. Compare the performance of MWNTs-starch derivative-based CSPs with existing CSPs.Methodology:1. Synthesize MWNTs-starch derivatives by oxidizing MWNTs and grafting them with starch derivatives.2. Characterize the synthesized MWNTs-starch derivatives using FT-IR, Raman spectroscopy, thermal gravimetric analysis (TGA), and scanning electron microscopy (SEM).精品文档---下载后可任意编辑3.

Optimization of separation conditions leading to further enhancement of the performance of MWNTs-starch derivative-based CSPs.4. Better understanding of the mechanism behind the separation efficiency of MWNTs-starch derivative-based CSPs.Conclusion:The development of MWNTs-starch derivative-based CSPs has the potential to significantly enhance the performance of HPLC for chiral separation. The proposed project aims to synthesize and evaluate the performance of this new CSPs, optimize the separation conditions, and compare their performance with commercial CSPs and other CNT-based CSPs. The successful outcome of this study can lead to the development of new CSPs with improved performance and resolution.
