signaling behavior in dimethylsulfoxide, indicated by a solution color change from yellow to pink, which was readily discernible without any external devices. Practical application of the sensor to the detection of Cu2+ in an aqueous solution containing other environmentally relevant metal ions by selective two-phase liquid-liquid extraction with ethyl acetate was possible. Particularly, extractive signaling
通过结合发色团3-羟基萘二甲酰亚胺和二氨基马来腈,开发了一种新的Cu 2 +-选择性比色传感器。传感器在二甲基亚砜中显示Cu 2 +-选择性比色信号传导行为,由溶液颜色从黄色变为粉红色表示,无需任何外部设备即可轻松辨别。该传感器可用于通过使用乙酸乙酯的选择性两相液-液萃取来检测含有其他与环境相关的金属离子的水溶液中的Cu 2+的实际应用。特别是,Cu 2+的提取信号 使用易于使用的智能手机作为比色数据捕获和分析工具成功地在模拟半导体废水中进行了分析。
