Experimental design and modelling of removal of dyes using nano-zero-valent iron: a simultaneous model

, 2019
The aim of the present study is to remove dyes from aqueous solutions since the dye compounds are harmful to human life and the environment. Nano-zero-valent iron particles were synthesised and used to remove the synchronisation of Direct Red-31 (DR-31 ...

Enhanced nitrate reduction by HPMC-stabilized nanoscale zero-valent iron (H-NZVI): Synthesis, characterization and reaction kinetics

Desalination and Water Treatment
Nano zero-valent iron (NZVI) was successfully stabilized by using hydroxypropyl methyl cellulose (HPMC). Systematic characterization observations (including XRD, TEM, FTIR, and VSM), as well as settling performance, illustrated that, compared to bare ...

Reduction of Hexavalent Chromium by Nano Zero-Valent Iron

Quality of Life (Banja Luka) - APEIRON
Hexavalent chromium is a toxic form of chromium that has significant health and environmental implications. Reducing hexavalent chromium to trivalent chromium is a crucial step in immobilizing and removing Cr(VI) from water resources. Nano zero-valent iron (nZVI) as an electron-donating agent was used for Cr(VI) reduction in aqueous solution.
