Abstract

C18-modified bipyridinium-functionalized silica was prepared and further modified with tetras(4-sulfonatophenyl)styrene (TPE-SO₃H) via ion bonding. Thus, two novel stationary phases, including C18-modified bipyridinium stationary phase (Sil-DPC18) and TPE-SO₃H-functionalized C18-modified bipyridinium stationary phase (Sil-DPC18-TPES) were obtained. The stationary phases were characterized by elemental analysis and Fourier transform infrared spectroscopy (FT-IR). The reversed-phase chromatographic performance of Sil-DPC18 and Sil-DPC18-TPES were evaluated using the Tanaka test mixture, alkylbenzenes, and linear polycyclic aromatic hydrocarbons (PAHs). Compared to an in-house Sil-C18, Sil-DPC18-TPES and Sil-DPC18 exhibited stronger aromatic selectivity and shape selectivity, but weaker hydrophobicity and hydrophobic selectivity. Furthermore, Sil-DPC18-TPES demonstrated better hydrophobicity, hydrophobic selectivity, aromatic selectivity and shape selectivity compared to Sil-DPC18. The enhancement could be due to the introduction of TPE-SO₃H. In addition, Sil-DPC18-TPES and Sil-DPC18 exhibited good separation selectivity for PAHs, phenylesters, phenols, and phenylamines compared to Sil-C18.

离子键法调节c18修饰联吡啶固定相的反相色谱性能

制备了c18修饰的联吡啶功能化二氧化硅，并通过离子键对四（4-磺基苯乙烯）苯乙烯（TPE-SO3H）进行了改性。从而得到了c18修饰联吡啶固定相（Sil-DPC18）和tpe - so3h官能化c18修饰联吡啶固定相（Sil-DPC18- tpes）两种新型固定相。用元素分析和傅里叶变换红外光谱（FT-IR）对固定相进行了表征。采用Tanaka测试混合物、烷基苯和线性多环芳烃（PAHs）评价Sil-DPC18和Sil-DPC18- tpes的反相色谱性能。与硅- c18相比，硅- dpc18 - tpes和硅- dpc18具有更强的芳香选择性和形状选择性，但疏水性和疏水性选择性较弱。此外，与Sil-DPC18相比，Sil-DPC18- tpes具有更好的疏水性、疏水选择性、芳香选择性和形状选择性。这种增强可能是由于引入了TPE-SO3H。此外，与Sil-C18相比，Sil-DPC18- tpes和Sil-DPC18对多环芳烃、苯酯、酚类和苯胺具有良好的分离选择性。

期刊介绍： Separation sciences, in all their various forms such as chromatography, field-flow fractionation, and electrophoresis, provide some of the most powerful techniques in analytical chemistry and are applied within a number of important application areas, including archaeology, biotechnology, clinical, environmental, food, medical, petroleum, pharmaceutical, polymer and biopolymer research. Beyond serving analytical purposes, separation techniques are also used for preparative and process-scale applications. The scope and power of separation sciences is significantly extended by combination with spectroscopic detection methods (e.g., laser-based approaches, nuclear-magnetic resonance, Raman, chemiluminescence) and particularly, mass spectrometry, to create hyphenated techniques. In addition to exciting new developments in chromatography, such as ultra high-pressure systems, multidimensional separations, and high-temperature approaches, there have also been great advances in hybrid methods combining chromatography and electro-based separations, especially on the micro- and nanoscale. Integrated biological procedures (e.g., enzymatic, immunological, receptor-based assays) can also be part of the overall analytical process.
