Nanoscale zero-valent iron
particles (NZVI) were successfully immobilized in the PAA/PVDF film (PPN) for removal of Cr(VI).
Whitman, the New Jersey-based environmental, engineering and management firm, has received approval from the New Jersey Department of Environmental Protection to proceed with a remediation project that is believed to be among the first full-scale projects ever to use nano-scale zero-valent iron
for site remediation, a new technology pioneered by Whitman professionals.
Of these, nanoscale zero-valent iron
(nZVI) is currently the most widely used.

Techniques used to assist PS oxidation in the treatment of water and waste water include; thermal activation [8-10], photochemical activation [11-13], ferrous Ion activation [14, 15], chelated ferrous Ion activation , zero-valent iron
activation [17, 18], mineral activation [19, 20], activated carbon/PS activation , [22, 23], microwave activation , and integrated activation [25, 26].
The topics include decontaminating water by solar irradiation, degrading perchlorate dissolved in water by a combined application of ion exchange resin and zero-valent iron
nanoparticles, decontaminating commercial chlorpyrifos in water using the ultraviolet/hydrogen peroxide process, modified montmorillonite in photo-Fenton and adsorption processes, stabilized titania nanoparticles on clay minerals for air and water treatment, and the photodegradation of beta-blockers in water.
