摘要：

A simple and novel method for the colorimetric detection of Co2+ 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-Cu2+), the sensing of Co2+ showed high selectivity. The mechanism of sensing has also been discussed.
