Influencing factors and controlled release kinetics of HO from PVP-coated calcium peroxide NPs for groundwater remediation.

Calcium peroxide nanoparticles (nCP) as a versatile and safe solid source of hydrogen peroxide (HO) receive substantial attention from researchers as a potential groundwater remediation reagent. In this study, we synthesized polyvinylpyrrolidone-coated calcium peroxide nanoparticles (PVP@nCP-PVP) to control the release rate of HO and modulate pH fluctuation simultaneously. The PVP@nCP-PVP is fully characterized and the HO releasing kinetics and mechanisms are investigated.
