Abstract

Urea is a simple organic compound that is widely used in both the industry and daily life. Compared with conventional methods, the preparation of urea by electrochemical synthesis is more environmentally friendly and sustainable. However, after the reaction, low amounts of urea and high concentrations of inorganic ions, including [Formula: see text] concentration was achieved without interference. Thus, the developed method can be applied for the detection of trace urea and other related ions in urea-containing electrolyte products.

摘要

尿素是一种简单的有机化合物，在工业和日常生活中都有广泛应用。与传统方法相比，通过电化学合成制备尿素更环保且可持续。然而，反应后，尿素含量低且无机离子浓度高，包括[化学式：见原文]，在无干扰的情况下实现了浓度测定。因此，所开发的方法可用于检测含尿素电解质产品中的痕量尿素及其他相关离子。
