Immobilized nanoscale zero-valent iron for synergistic enhanced removal of pentachlorobenzene with Pseudomonas sp. JS100 [PDF]

Frontiers in Bioengineering and Biotechnology, 2022
Highly chlorinated benzenes usually have a low efficient degradation in environment. Here we proposed a synergistic removal strategy of pentachlorobenzene (PeCB) using Pseudomonas sp. JS100 coupled with immobilized nanoscale zero-valent iron (NZVI).

Synthesis of Bare and Four Different Polymer- Stabilized Zero-Valent Iron Nanoparticles and Their Efficiency on Hexavalent Chromium Removal from Aqueous Solutions [PDF]

Journal of Water and Environmental Nanotechnology, 2017
Zero-valent iron particles at the nanoscale are proposed to be one of the important reductants of Cr(VI), transforming the same into nontoxic Cr(III). In this study zero valent iron nanoparticles(ZVINs) were synthesized and characterized for hexavalent ...
