Abstract Detection of cationic species represents an important field due to its importance in biological and environmental processes. This communication shows the synthesis and application of an ascorbic acid-based quinoxaline derivative (1) in the colorimetric detection of Cu2 + against several other cationic species, including Sr2 +, Fe2 +, Pb2 +, Mn2 +, Mg2 +, Ni2 +, Zn2 +, Sn2 +, Hg2 +, Ca2 +,
摘要 由于其在生物和环境过程中的重要性,阳离子物种的检测代表了一个重要的领域。本通讯展示了基于抗坏血酸的喹喔啉衍生物 (1) 的合成和应用,用于比色检测 Cu2 + 对其他几种阳离子物质的检测,包括 Sr2 +、Fe2 +、Pb2 +、Mn2 +、Mg2 +、Ni2 +、 Zn2+、Sn2+、Hg2+、Ca2+、Ba2+、Co2+、Cr3+、Al3+ 和 Fe3+。基于实验和理论结果,提出了一种涉及1和Cu2+的1:2结合模型。
