Highly selective removal of thallous ions from wastewater using Prussian Blue biochar composite.

ABSTRACT: Thallium, a highly toxic pollutant, shows greater toxicity to human than other common heavy metals such as mercury, lead, cadmium and its effective removal from wastewater gains great attention. The main restriction for the Tl⁺ removal is the interference of a high concentration of co-existing ions in wastewater. Therefore, the goal of the current work was to synthesis adsorbent with high selectivity for the Tl⁺ removal. Herein, the pore size sieving strategy was proposed and Prussian blue-impregnated biochar (BC@PB) particles was synthesized. More than 95% Tl⁺ can be removed even the concentrations of the coexistence ions (Na⁺, Cd²⁺, and Zn²⁺) 1,000 higher than the initial concentration of Tl⁺ (500 μg/L). BC@PB a
