Functionalized microcrystalline cellulose crosslinked via diisocyanate-derived urethane bonds for wastewater treatment.

ABSTRACT: Copper is a common water pollutant due to its toxicity and widespread presence in various water 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
