DOI: 10.1016/j.chemosphere.2017.07.104
Abstract: The removal and degradation pathways of microcystin-LR (MC-LR, [M+H]+ = 995.6) in UV-B photolysis and UV-B/H2O2 processes were examined using liquid chromatography-tandem mass spectrometry. The UV/H2O2 process was more efficient than UV-B photolysis for MC-LR removal. Eight… read more here.
