Abstract

In this work, using discarded white pomelo peel as the green precursor and hydrochloric acid (HCl) as the dopant, water-soluble Cl–N-doped carbon dots (Cl-NCDs) with excellent performance were synthesized by one-step hydrothermal method. The Cl-NCDs function as both luminescent agents and catalysts, significantly enhancing the chemiluminescence intensity of the HCl–HCHO–KMnO₄ system, forming a novel HCl–HCHO-(Cl-NCDs)-KMnO₄ chemiluminescence system. The addition of erythromycin (EM) solution inhibits the chemiluminescence intensity of new system. By optimizing the conditions, we established a simple, cost-effective, and reliable chemiluminescence method for EM detection, offering a linear range of 5–100 μM and a detection limit of 0.0149 μM. In addition, this method was successfully applied to the analysis of EM in various water simples, achieving recovery rates ranging from 97.6 % to 106 %.

基于废柚皮的Cl-NCDs和KMnO4体系化学发光检测红霉素

本论文以废弃的白柚皮为绿色前驱体，以盐酸（HCl）为掺杂剂，采用一步水热法制备了性能优异的水溶性cl - n掺杂碳点（Cl-NCDs）。Cl-NCDs兼具发光剂和催化剂的作用，显著增强了HCl-HCHO - kmno4体系的化学发光强度，形成了一种新型的HCl-HCHO -(Cl-NCDs)- kmno4化学发光体系。红霉素溶液的加入抑制了新体系的化学发光强度。通过优化条件，建立了一种简单、经济、可靠的电磁检测化学发光方法，线性范围为5 ~ 100 μM，检出限为0.0149 μM。此外，该方法成功地应用于各种简单水样的电磁分析，回收率为97.6% ~ 106%。

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
