Luminol-doped nanostructured composite materials for chemiluminescent sensing of hydrogen peroxide

摘要

Silica based nanostructured composite materials doped with luminol and cobalt(II) ion were synthesized and characterized, resulting in a highly chemiluminescent material in the presence of hydrogen peroxide. A detection system with the CL light guided from the reaction tube to the photomultiplier tube using a one millimeter glass optical fiber was developed and assessed. A linear response was observed using a semi-logarithm calibration between 50-2000 μM hydrogen peroxide with 1 μM as the limit of detection.
