Polyacrylamide-phytic acid-polydopamine conducting porous hydrogel for rapid detection and removal of copper (II) ions

Abstract: In this work, a conducting porous polymer hydrogel-based electrochemical sensor has been developed for rapid detection of copper (II) ions (Cu). The polymer (termed as PAAM/PA/PDA) hydrogel is prepared through multi-interactions of the monomers dopamine (DA), acrylamide (AAM) and phytic acid (PA) under mild ambient conditions: the AAM polymerizes through free-radical polymerization, DA occurs poly coupling reaction, and PA crosslinks polydopamine (PDA) and polyacrylamide (PAAM) by hydrogen bonds. The three dim… Show more

“…Among many metal ions, copper ion (Cu 2+ ) represents one of the most important problems due to inappropriate discharges in the smelting and mining industries [5]. Excessive intake of Cu 2+ induces serious neurodegenerative diseases and causes damage to living organisms [1]. Many treatment techniques have been adopted for removing Cu 2+ from aqueous streams, and adsorption is considered to be a promising technology because of its easy operation, high efficiency, wide application range and good cost effectiveness [2,5,6].…”

“…Therefore, it is a challenge to try to strike a balance between detection performance and hydrogel conductivity. Phytic acid (PA) is an exception that is used to form hydrogels, and is consequently used for sensing purposes [64,65]. A highly sensitive electrochemical detector for copper ions can be prepared by multiple interactions of dopamine (DA), acrylamide (AAM), and PA, under mild environmental conditions [64].…”

“…Moreover, Cu 2+ and Fe 3+ cause ecological and environmental problems. Thus, to minimize the harm of excess Cu 2+ and Fe 3+ , great efforts have been made to develop highly sensitive and selective methods to detect Cu 2+ and Fe 3+ [9,10,11,12,13,14].…”
