Abstract

Argentometric titrations are traditional and widely recognized methods for detecting halide ions. However, their practical application is often constrained by challenges such as pH control and reliance on specific indicators. In this study, we introduce a novel optical indicator for argentometric titration, based on previously reported Janus droplet systems and employing cetyltrimethylammonium bromide (CTAB) and Zonyl as surfactants. Furthermore, Janus droplets were utilized to explore the impact of various cations on the efficiency of the CTAB surfactant, revealing that contact angle values are influenced by the cations' positions within the Hofmeister series.

响应性 Janus 乳液作为传统精滴定法的非传统指示剂

阿根廷滴定法是检测卤化物离子的传统方法，也是公认的方法。然而，其实际应用往往受到 pH 值控制和依赖特定指示剂等难题的制约。在本研究中，我们以之前报道的 Janus 液滴系统为基础，采用十六烷基三甲基溴化铵（CTAB）和 Zonyl 作为表面活性剂，介绍了一种用于精馏滴定的新型光学指示剂。此外，我们还利用 Janus 液滴探索了各种阳离子对 CTAB 表面活性剂效率的影响，发现接触角值受阳离子在霍夫迈斯特系列中位置的影响。
