The mineralization rate is the key indicator of whether the organic pollutants can be completely transformed to water and carbon dioxide in the oxidative degradation process. The performance of ranitidine mineralization was poor in the Co@VMT nanosheets/PMS system (11.49%) and PMS only system (5.84...
