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 and encapsulation efficiency of PMCM were 30.3%
and 42.6% respectively. Potassium monopersulfate was fully released after 8 h, following a Fickian diffusion
mechanism. Results showed that the microcapsules prepared with a high concentration of potassium monopersulfate solution showed a good antimicrobial effect. The microcapsule wall of the resulting PMCM increased with
increasing ethyl cellulose content and had high thermal stability from the data of 69% residue rate. The excellent
thermal stability and high sustained release performance of PMCM showed high application value.},
