Arsenic and Biosorption

, 2023
Arsenic, either in (III) or (V) oxidation states forms, is a hazardous element to humans; thus, its removal from aqueous environments is of the utmost priority in the countries where this problem arises. From the various separation technologies, the removal of arsenic via biosorption processing attracted an interest, because besides the removal of the ...

Bioremediation of Crystal Violet Dye Using Sapindus mukorossi Functionalized Iron‐Oxide Nanoparticles From Coprecipitation Method

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The textile industry is a water‐intensive industry that disrupts aquatic ecosystems by releasing recalcitrant chemicals like crystal violet (CV) dye characterized by its carcinogenic and mutagenic nature. Ethanolic extract of saponin‐rich Sapindus mukorossi was employed in the synthesis of biogenic iron oxide nanoparticles (IONP).

Study on iron anchoring methods for magnetic biochar: Characterization, functional mechanism, and RBBR dye removal

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Magnetic biochar (MBC) is a novel bio‐metallic composite material with high potential in sustainable water cleaning. Iron anchoring is critical in forming iron‐based MBC and will fundamentally impact its characteristics and functionality in dye removal applications. However, the mechanism is not well‐revealed.
