Biochar is a carbon-rich material that can be obtained from pyrolysis of solid waste (eg,
agricultural solid waste and sludge from wastewater treatment plants). Biochar features low …

Scientists studying the environment, physiology, and biology have been particularly
interested in nickel (Ni) because of its dual effects (essentiality and toxicity) on terrestrial …

The present era is seeking our attention on the dilemma caused by the contamination of the
aquatic system with chromium (Cr) and nickel (Ni). Amid Ni and Cr oxidation states …

This work aimed to develop innovative material by combining properties of magnetic-biochar
(derived from peanut shells) and hydrogel bead (MBA-bead) and apply it for adsorbing Cu …

Adsorption has become the most popular and effective separation technique that is used
across the water and wastewater treatment industries. However, the present research …

Nickel (Ni) is a potentially toxic element that contaminates soil and water, threatens food and
water security, and hinders sustainable development globally. Biochar has emerged as a …

This study investigated the impact of pyrolysis conditions on physical characteristics of date
palm fronds biochars and their performances for aqueous uptake of anionic dyes—methyl …

Addressing the critical issue of global water scarcity requires sustainable solutions. This
overview focuses on the synthesis, modification, and regeneration of chitosan-based porous …

Effective management of harmful contaminants from waste effluent is crucial for a
sustainable environment. Herein, the efficient adsorbent, sawdust-derived biochar doped …

Abstract Background Hexavalent chromium [Cr (VI)] is a highly toxic heavy metal because of
its high movement in cell membranes as HCrO 4− and CrO 4 2− ions. Metal oxide decorated …
