Aqueous contaminant removal in the presence of metallic iron is often regarded as a reductive transformation mediated by the Fe surface. However, successful removal of theoretically non-reducible contaminants has been largely reported. This paper presents a rebuttal of the concept of contaminant reductive transformation. It is argued through a careful examination of the evolution of the volume ...

A comparison of adsorption efficiency of the three Granular Activated Carbon (GAC) produced from waste Nigerian Bamboo at different level of activation in a fixed adsorption bed is reported. Bamboo carbonization was done at temperature range of 200-400c and chemically activated at 400c with chloride salt at percentage range of 0-20%. The 0, 10 and 20% level activation were selected for water tr...

Widespread occurrences of endocrine-disrupting chemicals (EDCs) in waterways have attracted a great attention of the scientific community. While scientific evidence associated with human health is restricted due to the long-term effects, impacts of EDCs on trout at the common concentration encountered in sewage effluent have been confirmed by both in vitro and in vivo studies. The impacts of st...

The purpose of this study is to investigate the adsorption characteristics granular aggregates under identical experimental conditions for potential applications in highly adsorptive concrete. In study, industrial by-products (steel slag), lightweight (expanded silica) and bio-materials (peach shell miscanthus) are used phosphorus (P) removal from aqueous solutions. effects several parameters s...
