摘要：

Acute toxicity from thallium (Tl) contamination poses significant risks to ecosystems and human health. Purifying Tl(I)-containing smelting wastewater is challenging due to the high mobility of Tl(I) and the complexity of such wastewater. As a soft acid, Tl(I) preferentially interacts with soft bases based on soft-hard interaction principles. In this study, we developed a pyrrolic-nitrogen-carbon sponge (NCS) as a model adsorbent for rapidly removing Tl(I) from complex aqueous environments, leveraging pyrrolic-N as a distinct soft base. The thr...
