摘要：

An efficient catalytic system was developed to remove various organic pollutants by simultaneously using low-level cobalt ions, calcium carbonate micro-particles and peroxymonosulfate (PMS). A simple base-induced precipitation was used to successfully loaded Co-centered reactive sites onto the surface of CaCO3 microparticles. Under optimal conditions at 25 °C, 10 mg/L methylene blue (MB) could be completely degraded within 10 min with 480 µg/L Co2+, 0.4 g/L CaCO3 microparticles (or 0.4 g/L Co@CaCO3) and 0.1 g/L PMS. The MB degradation followe...
