Title: SYNTHESIS OF A THIN INSOLUBLE HYDROXIDE SHELL ON THE SURFACE OF MAGNETIC ZERO-VALENT METAL NANOPARTICLES FOR ENVIRONMENTAL REMEDIATION
Abstract:
An insoluble thin hydroxide shell is synthesized on the surface of nanoscale zero-valent iron (NZVI), using a rate-controlled deprotonation method. The hydroxide coated NZVI remains suspended in aqueous phase better than the prior art and can be used to remove groundwater contaminants.
