Eggshell‐Based Biochar for Superior Adsorption of Crystal Violet Dye and Fluoride From Wastewater

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Present study investigates the efficiency of eggshell biochar as a low‐cost and ecofriendly adsorbent for the simultaneous removal of fluoride ions and crystal violet (CV) dye from wastewater. The eggshell waste was pyrolyzed to produce biochar, which was thoroughly characterized and subsequently employed for contaminant adsorption.

Adsorption Characteristics and Mechanisms of Dibutyl Phthalate on Nanomaterials

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Dibutyl phthalate (DBP) is a widely used plasticizer whose environmental release poses significant risks to ecosystems and human health. This study systematically investigated DBP adsorption on three common nanomaterials—titanium dioxide nanoparticles (n‐TiO2), multiwalled carbon nanotubes (MWCNTs), and carboxylated MWCNTs (MWCNTs‐COOH)—using ...

Converting Durian Husk Into Adsorbent Beads for Methylene Blue Adsorption: Synthesis, Kinetics, Isotherms, and Reusability

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Environmental pollution from textile dyeing wastewater, particularly the discharge of harmful dyes like methylene blue (MB), poses a significant challenge. This study presents an innovative solution for dyeing wastewater treatment by utilizing durian husk, an agricultural waste, as an adsorbent for MB removal.
