The oxide film coated on the surface of zero-valent iron (ZVI) greatly limits the reducibility of
ZVI. Application of iron-based materials especially microscale or nanoscale for water …

Circumneutral surface water and groundwater can contain hazardous concentrations of
metals and metalloids that can threaten organisms in surrounding ecosystems. Extensive …

Abstract Following the 2015 Paris Agreement, the main challenge for world economies
nowadays is to commit themselves to long-term reforms aimed at increasing and promoting …

A novelty process based on sodium salt roasting-(NH 4) 2 SO 4 leaching was proposed to
extract vanadium and chromium in high chromium vanadium slag (HCVS). V 2 O 5 and Cr 2 …

The application of microscale zerovalent iron (mZVI) in the removal of Cr (VI) from water is
plagued with the readily formation of oxide passivation layer. In this study, we propose a …

It is a long-term goal to develop an inexpensive, eco-friendly, and effective approach for the
purification of wastewater containing heavy metal elements such as Cr (VI). In this study, a …

There is a growing concern about how to minimize the impact of human activities on the
environment. Already nowadays, in some places adaptation efforts are needed in order to …

Chromium–containing vanadium tailings (CCVT), an industrial waste, were utilized to extract
chromium efficiently by soda roasting–water leaching process and for the preparation of …

The influence of iron corrosion products (FeCPs) on the efficiency of metallic iron (Fe 0) for
aqueous contaminant removal is characterized. Quiescent batch experiments were …

Escalated levels of arsenic (As) in drinking water is an urgent environmental problem that
has attracted increasing public concern. The need for effective removal of As has motivated …
