Thiourea dioxide as a unique eco-friendly coreactant for luminol chemiluminescence in the sensitive detection of luminol, thiourea dioxide and cobalt ions

Thiourea dioxide, a green industrial reductant, has been explored as an efficient chemiluminescence coreactant for the first time. Luminolthiourea dioxide chemiluminescence can be significantly enhanced by Co2+. This system enables the sensitive detection of thiourea dioxide, luminol and Co2+, being particularly selective for Co2+ detection.
