摘要：

In this research, a new synthesis approach was developed for an adsorbent, namely the phosphorylated ZIF-8/bamboo charcoal/chitosan/tannic acid (P-ZBCT) composite, for the efficient adsorption of uranyl ions from wastewater at low dosages. Impressively, the uranium adsorption rate of P-ZBCT reaches up to 98 % at a low dosage of 0.056 g/L in a 10-mg/L uranium solution, outperforming most reported uranium adsorption materials. The theoretical maximum adsorption capacity of P-ZBCT for uranium at 308 K and pH 6.0 is 2357.69 mg/g, with uranium ...
