Hydrogels are important functional materials with a myriad of potential applications. As the
chemically stable and interlocked polymeric network retains vast amounts of water without …

Toxic heavy metals released into the environment without treatment would contaminate the
water quality and persistence in the environment. Recently, the polymer polyethyleneimine …

Heavy metal ion pollution leads to severe health risk to human beings. Herein, a natural and
highly efficient sodium alginate (ALG)/polyethyleneimine (PEI) composite hydrogel was …

Adsorption using conventional activated carbon is considered an effective and practical
method for per-and polyfluoroalkyl substances (PFAS) removal from contaminated water …

In the present work bio-composite adsorbents were prepared by incorporating natural nano-
sized hydroxyapatite (nHAp) into alginate polymer. Bead and film form composite …

The biosorption process of three divalent metal ions–nickel, lead and zinc–from on calcium
alginate from aqueous solution was studied, in single component systems. The biosorbent …

Granular alginate-based hydrogels were prepared in situ in an aqueous solution via grafting
and crosslinking reactions among sodium alginate (SA), acrylic acid (AA) …

This study highlights the potential of Hal/alginate nanocomposite beads for the removal of
Pb 2+ in aqueous solutions. This is based on comprehensive physicochemical–mechanical …

Hydrogels based on chitosan, maltodextrin and gum arabic with and without magnetite
nanoparticles were employed as adsorbents for removing Cd2+ from aqueous solutions …

In present paper, the influence of the initial pH and concentration of Pb2+ on its adsorption
by the natural (NZA) and Fe (III)-modified zeolite-alginate beads (FeA) was studied. Results …
