streams. Various adsorbents have been utilized to remove heavy metal contaminants from water;
however, these methods often show limited efficiency and can incur significant costs. This work
highlights the synthesis, characterization, and performance evaluation of new crosslinked cellulosic
polymers in foam form functionalized with alkylsulfonate moiety for use as efficient adsorbents
for copper and other metal ions. Cellulose was first reacted with butane sultone and subsequently
crosslinked using p-phenylene diisocyanate and hexamethylene diisocyanate to produce Cell-S-PPF
and Cell-S-HMF, respectively. The capacities of Cell-S-PPF and Cell-S-HMF for extracting metal ions
from wastewater, along with their optimal adsorption conditions, were evaluated. The Qe values
for both polymers were determined to be 19.2 mg/g and 20.0 mg/g for Cell-S-HMF and Cell-F-PPF,
respectively. Adsorption proceeded spontaneously at ambient temperature as evidenced by negative
Gibbs free energy values. Both polymers showed the ability to quantitatively remove more than 25
metal ions present in a sewage sample, including uranium. Recycling performance shows that Cell-SPPF
and Cell-S-HMF can be recycled by sequential washing with diluted acid and then base, without
observable performance loss over at least five adsorption–desorption cycles. The adsorption process
obeys the Langmuir isotherm model with a second-order rate. The findings suggest a promising avenue
for the commercialization of these materials in wastewater treatment applications. Monte Carlo
(MC), DFT, and Dynamic (MD) simulations indicated strong bonding between copper (II) ions and the
coordination sites of cellulosic polymers. Since high adsorption negative energy was obtained.
