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.
