Phytoextraction by arsenic hyperaccumulator Pteris vittata L. from six arsenic-contaminated soils: Repeated harvests and arsenic redistribution
(2008)
This greenhouse experiment evaluated arsenic removal by Pteris vittata and its effects on arsenic redistribution in soils. P. vittata grew in six arsenic-contaminated soils and its fronds were harvested and analyzed for ...
The effect of substrate media on the removal of arsenic, boron and iron from an acidic wastewater in planted column reactors
(Elsevier, 2012-01)
Acidic wastewaters, such as occur in acid mine drainage, typically contain heavy metals and metalloids that pose a serious threat to receiving waters, due to their high toxicity. In this study, vertical flow wetland columns, ...
Arsenic removal using horizontal subsurface flow constructed Wetlands: A sustainable alternative for arsenic-rich acidic waters
(MDPI AG, 2018)
Constructed wetlands (CW) have been widely used to treat different types of water, including acid mine drainage (AMD). However, little is known about their performance in the removal of As from AMD. In this study, a ...
Influence of Redox Environments on the Solubility of Arsenic in Soils
(TAYLOR & FRANCIS INC, 2009)
Arsenic (As) is a semimetallic element that is notorious for its toxicity and carcinogenicity. Arsenic can be removed by some ferns. The objectives of this study were to investigate the ability of Pteris vittata L. ...
Review of coagulation technology for removal of arsenic: Case of Chile
(I C D D R B-CENTRE HEALTH POPULATION RESEARCH, 2006-09)
Coagulation technology has been used since 1970 in northern Chile for removing arsenic from drinking-water. This experience suggests that coagulation is an effective technology for the removal of arsenic. It is currently ...
REMOVAL OF ARSENIC FROM ENARGITE RICH COPPER CONCENTRATES
(JOHN WILEY & SONS INC, 2013)
Arsenic is a troublesome impurity in copper concentrates where it is usually present as enargite (CU3AsS4). When the enargite content is high in the concentrates, they cannot be treated by direct smelting processes because ...
Effect of operating conditions in removal of arsenic from water by nanofiltration membrane
(Elsevier Science, 2005-02-10)
The removal of arsenic from synthetic waters and surface water by nanofiltration (NF) membrane was investigated. In synthetic solutions, arsenic rejection experiments included variation of arsenic retentate concentration, ...
