A simple and novel method for the colorimetric detection of Co(2+) was developed based on controlling the oxidation level of methylene blue (MB). After a complex was formed between MB, 2-aminothiophenol (ATP) and copper nitrate (MB-ATP-Cu(2+)), the sensing of Co(2+) showed high selectivity. The mechanism of sensing has also been discussed.
基于控制亚甲基蓝 (MB) 的氧化水平，开发了一种用于检测 Co(2+) 的简单新颖的比色法。在 MB、2-巯基苯胺 (ATP) 和硝酸铜 (MB-ATP-Cu(2+)) 形成配合物后，对 Co(2+) 的检测表现出高选择性。还讨论了传感的机制。
