The thermoresponsive micellar phase behaviour that exhibits the Triton-X-100 micelles by temperature effect and addition of salt in the extraction process of metallic ions was explored from mesoscopic and experimental points. In the theoretical study, we analyse the formation of Triton-X-100 micelles, load and stabilization of dithizone molecules and metallic ions extraction inside the micellar core at room temperature; finally, a thermal analysis is presented. In the experimental study, the spectrophotometric outcomes confirm the solubility of the copper-dithizone complex in the micellar core, as well as the extraction of metallic ions of aqueous environment via a cloud-point at 332.2 K. The micellar solutions with salt present a low absorbance value compared with the micellar solutions without salt. The decrease in the absorbance value is attributed to a change in the size of hydrophobic region of colloidal micelles. All transitory stages of extraction process are discussed and analysed in this document.

金属离子萃取过程中表面活性剂胶束相的补充实验-模拟研究:温度和盐浓度的影响

从介观和实验角度探讨了通过温度效应和盐分添加在金属离子提取过程中表现出Triton-X-100胶束的热响应胶束相行为。在理论研究中,我们分析了室温下Triton-X-100胶束的形成,双硫zone分子的负载和稳定以及胶束核心内部金属离子的提取;最后,进行了热分析。在实验研究中,分光光度法的结果证实了铜-二硫zone配合物在胶束核心中的溶解度,以及通过332.2 K的浊点提取水性环境中的金属离子。吸光度值与不含盐的胶束溶液相比。吸光度值的降低归因于胶体胶束的疏水区尺寸的变化。本文档中讨论并分析了提取过程的所有过渡阶段。
