Abstract:
Scientists have been encouraged to find different methods for removing harmful heavy
metal ions and dyes from bodies of water. The adsorption technique offers promising outcomes for
heavy metal ion removal and is simple to run on a large scale, making it appropriate for practical
applications. Many adsorbent hydrogels have been developed and reported, comprising N,Ndimethylacrylamide (DMAA)-based hydrogels, which have attracted a lot of interest due to their
reusability, simplicity of synthesis, and processing. DMAA hydrogels are also a suitable choice for
self-healing materials and materials with good mechanical properties. This review work discusses
the recent studies of DMAA-based hydrogels such as hydrogels for dye removal and the removal of
hazardous heavy metal ions from water. Furthermore, there are also references about their conduct
for self-healing materials and for enhancing mechanical properties.
