Abstract

The hydrochloric acid (HCl 0.1 M) supporting electrolyte was used in the electrochemical estimation cyclic voltammetry for CaCl2 concentrations also using crystal violet dye or (hexamethyl pararosaniline) as ligand. For oxidation and reduction waves, the potential range is 0.5 V, -0.5 V. The interaction of calcium ions with crystal violet was examined using several analytical estimates, and kinetic and thermodynamic parameters. The analytical concentration for calcium ions in different samples especially in Nile River were estimated in the range from 1.6 to 14.3 mmol. The estimation of calcium ion concentrations was achieved up to 11.49 mmol in waste water in Mansoura University. Applications were made for calcium estimation of different water samples and molecular docking of the calcium-crystal violet complex against the Hepatitis C viral proteins (4i33, 4KTC), roving strong bonds of interaction were observed. And anti-bacterial effect on calcium complex with crystal violet and face mask N-95 tissue.

在无结晶紫和有结晶紫的盐酸溶液中使用金电极测定水样中的钙含量及环境研究

盐酸（HCl 0.1 M）支持电解质被用于对 CaCl2 浓度进行电化学估计循环伏安法，同时使用水晶紫染料或（六甲基对位氨基苯胺）作为配体。氧化波和还原波的电位范围为 0.5 V、-0.5 V。利用几种分析估计值以及动力学和热力学参数对钙离子与水晶紫的相互作用进行了研究。不同样品（尤其是尼罗河中的样品）中钙离子的分析浓度估计范围为 1.6 至 14.3 mmol。在曼苏拉大学的废水中，钙离子浓度的估算值高达 11.49 mmol。应用该方法对不同水样进行了钙估算，并对钙-水晶紫复合物与丙型肝炎病毒蛋白（4i33、4KTC）进行了分子对接，观察到了强相互作用键。钙与水晶紫复合物与面膜 N-95 组织的抗菌效果。关键词：钙离子；热力学性质；溶解参数；尼罗河水样；抗菌；分子对接 Bull.Chem.Soc.2024, 38(1), 43-54.DOI: https://dx.doi.org/10.4314/bcse.v38i1.4
