Thallium, a highly toxic trace element, being released into the environment by industrial mining has caused serious environmental pollution. Here, a magnetic Prussian Blue (PB) nanosorbent loading on sepiolite (PB/Fe₃O₄/SEP) was successfully synthesized for the deep treatment of Tl(I) based on its high adsorption capacity. The high adsorption capacity of up to 558 mg/g helps the nanosorbents efficient adsorption of trace Tl(I) in wastewater. Then the strong magnetic help convenient removal from wastewater. Moreover, its excellent anti-disturbance properties in a wide range of pH indicated that it is suitable for complex wastewater treatments. Overall, the magnetic nanocomposite with excellent adsorption properties and high interference resistance can be applied for emergency treatment in actual Tl(I) contaminated water.

铊是一种剧毒微量元素，工业采矿过程中释放到环境中，造成了严重的环境污染。在此，成功合成了负载在海泡石上的磁性普鲁士蓝（PB）纳米吸附剂（PB/Fe ₃ O ₄ /SEP），基于其高吸附能力，用于深度处理Tl（I）。高达558 mg/g的高吸附容量有助于纳米吸附剂有效吸附废水中的痕量Tl(I)。然后强磁性有助于方便地从废水中去除。此外，其在较宽pH范围内具有优异的抗干扰性能，适合复杂的废水处理。总体而言，磁性纳米复合材料具有优异的吸附性能和高抗干扰性，可用于实际Tl(I)污染水体的应急处理。
