    Abstract Environmental cleaning is an important aspect of bacteria control. Ethyl cellulose microcapsules containing potassium monopersulfate (PMCM) were prepared by emulsified solvent diffusion method. The chemical structure and microstructure of the obtained PMCM was characterized by methods of Fourier transform infrared spectroscopy (FT-IR), optical microscopy, scanning electron microscopy and X-ACT energy dispersive X-ray spectroscopy. The SEM micrographs of the PMCM containing 21.6% of C, 46.8% of O, 10.7% of S and 19.4% of K was relatively smooth. Thermal stability, sustained release performance, and antimicrobial activity of PMCM were investigated. The results showed that the drug loading More >
