Textile wastewater heavy metal pollution has become a severe environmental problem
worldwide. Metal ion inclusion in a dye molecule exhibits a bathochromic shift producing …

Fly ash, generated during the combustion of coal for energy production, is an industrial by-
product which is recognized as an environmental pollutant. Because of the environmental …

Rice husk, which is a relatively abundant and inexpensive material, is currently being
investigated as an adsorbent for the removal of various pollutants from water and …

Purpose Biochar derived from waste biomass is now gaining much attention for its function
as a biosorbent for environmental remediation. The objective of this study was to determine …

In this article, the technical feasibility of various low-cost adsorbents for heavy metal removal
from contaminated water has been reviewed. Instead of using commercial activated carbon …

Heavy metal remediation of aqueous streams is of special concern due to recalcitrant and
persistency of heavy metals in environment. Conventional treatment technologies for the …

Hexavalent chromium is a well-known highly toxic metal, considered a priority pollutant.
Industrial sources of Cr (VI) include leather tanning, cooling tower blowdown, plating …

Among various water purification and recycling technologies, adsorption is a fast,
inexpensive and universal method. The development of low-cost adsorbents has led to the …

Abstract A Cr (VI)-imprinted-poly (4-VP-co-EGDMA)(IIP) was proposed to be used in the
process of selective extraction of low concentration of Cr (VI) ion from aqueous solution. The …
