开发了一种新型共轭吸附剂，用于同时检测和从城市采矿废物中回收 Au(III)。该吸附剂具有较大的表面积与体积比，其笼腔内的纳米结构具有形状均匀的孔。因此，结合吸附剂可以通过基于稳定络合[Au(III)-DHDM](n+)机制的比色肉眼可视化快速且特异性地捕获Au(III)离子。最佳条件下新型吸附剂的检测限和吸附容量分别为0.22 μg/L和183.42 mg/g。这种新型吸附剂的设计为超痕量 Au(III) 检测和回收提供了简单的程序，无需使用高度复杂的仪器。 (C) 2013 年韩国产业工程化学学会。由 Elsevier B.V. 出版。保留所有权利。
A novel conjugate adsorbent was developed for simultaneous Au(III) detection and recovery from urban mining waste. This adsorbent has the large surface area-to-volume ratios and uniformly shaped pores in the nanostructures in its cage cavities. Therefore, the conjugate adsorbent permitted to fast and specific Au(III) ions capturing via a colorimetric naked-eye visualization based on stable complexation [Au(III)-DHDM](n+) mechanism. The detection limit and sorption capacity of the novel adsorbent at optimum conditions was 0.22 mu g/L and 183.42 mg/g, respectively. The design in such novel adsorbent offered a simple procedure for ultra-trace Au(III) detection and recover without using highly sophisticated instruments.
