    Applications and impact of nanocellulose based adsorbents
    (Springer, 2020) Köse, Kazım; Mavlan, Miran; Youngblood, Jeffrey P.
    Abstract Efficient separation and removal is necessary in applications ranging from environmental remediation to the food sector. A well-designed adsorption system should meet the demands for high efficiency in a cost and time effective manner. In wastewater treatment, the ideal chemical feedstock used to synthesize the adsorbents should themselves been environmentally friendly (i.e. non-toxic) to avoid subsequent environmental issues. Nanocellulose, made of the most abundant organic biopolymer on earth, fulfills many criteria to fit the profile of a highly safe, but efficient adsorbent. A survey of the literature reveals that nanocellulose materials have a proven track record as viable alternatives as adsorbents. To summarize these recent advances, this review describes the methodologies under current use for such designs and gives a systematic overview of these technologies to promote a more focused research in the future for nanocellulose based adsorbent materials

    TEMPO-oxidized cellulose nanofiber based polymeric adsorbent for use in iron removal
    (Springer, 2020) Kose, Kazim; Mavlan, Miran; Nuruddin, Md; Youngblood, Jeffrey P.
    Cellulose nanofibrils (CNFs), as one of the most abundant renewable nanomaterials, has garnered interest in numerous fields owing to its many any advantages such as good mechanical properties, high surface area and surface tunability. Recently, CNFs have been shown to be a valuable candidate in water and soil treatment. In this study, adsorption of Fe(II) cations onto poly(2-hydroxy ethyl methacrylate-glycidyl methacrylate) cryogels was improved by addition of TEMPO-oxidized cellulose nanofibers (CNF). Characterization of CNF modified polymeric structures was performed using scanning electron microscopy. The effects of varying pH, initial Fe(II) concentration, and time were investigated during the study and a comparison was made to Fe(III) adsorption. Kinetic calculations were performed using Langmuir, Freundlich and Redlich-Peterson adsorption models.to understand the binding of Fe(II) cations onto the composite cryogel.
