Journal ArticleDOI
Adsorption behaviour and mechanisms of cadmium and nickel on rice straw biochars in single- and binary-metal systems.
TL;DR: Results from this study suggest that types and concentrations of metal ions should be taken into account when removing metal contaminants from water or soil using biochars.
Journal ArticleDOI
Studies on the optimum conditions using acid-washed zero-valent iron/aluminum mixtures in permeable reactive barriers for the removal of different heavy metal ions from wastewater
TL;DR: The method of permeable reactive barriers (PRBs) is considered as one of the most practicable approaches in treating heavy metals contaminated surface and groundwater and the reaction mechanism of the heavy metal ions with ZVI/ZVAl was discussed.

Dynamic molecular structure of plant biomass-derived black carbon (biochar)
TL;DR: A molecular-level assessment of the physical organization and chemical complexity of biomass-derived chars and, specifically, that of aromatic carbon in char structures suggests the existence of four distinct categories of char consisting of a unique mixture of chemical phases and physical states.
