Cover Story (view full-size image): This paper reports a one-step method to fabricate a novel sodium alginate-polyacrylamide (Alg–PAM) composite aerogel, which exhibits high affinity and selectivity towards Pb2+. The prepared Alg–PAM is a macroscopic adsorbent that can be easily applied for solid–liquid separation. This adsorbent can be regenerated by simple acid washing, and its adsorption performance remains stable after repeated use. Given its use of low-cost and green raw materials, simple preparation process, and high efficiency removal performance, Alg–PAM has broad application potential in treating heavy metal ions in wastewater.
