Advanced Cellulosic Materials for Treatment and Detection of Industrial Contaminants in Wastewater

Abstract

The scarcity of fresh, clean water is one of the most tremendous global crises currently facing the human race. Various technologies exist for the treatment of contaminated water on different waste volume scales, for specific pollutants, and at a range of cost points. The use of agricultural and industrial by‐products directly or with simple modifications for treating wastewater has been investigated thoroughly, and the new frontier in this field is the development of advanced cellulose materials which are low cost, highly efficient, and widely applicable. Concurrently, developing highly sensitive and selective methods for analyzing the remediation efficiency of these materials is important as low concentrations of industrial contaminants can cause severe health problems in humans. The focus of this review is current progress in advanced cellulose materials for treatment of industrially‐contaminated wastewater, particularly that which contains dyes, heavy metals, and petrochemicals, and the development of ultrasensitive technologies such as photothermal spectroscopy (PTS) and photoacoustic spectroscopy (PAS) for pollutant detection.

Nanocrystalline Cellulose-Derived Doped Carbonaceous Material for Rapid Mineralization of Nitrophenols under Visible Light

“…NCs is a new class of nanomaterial derived from cellulose, which is a naturally abundant, biodegradable, biocompatible, and renewable source. , NCs have garnered much attention in recent years owing to its unique physicochemical properties and myriad applications. , NCs possess high specific surface area, high crystallinity, superior mechanical strength, and tunable chemistry .

Facile synthesis of ZnO/CuO/Ag2O ternary metal oxide nanocomposite for effective photodegradation of organic water pollutants

“…The fast growing pollution, rapid rate of urbanization and industrialization exploited the natural resources extensively and a large amount of unchecked and unprocessed effluents are being discharged into the environment which pose grave threats to both biotic and abiotic elements of the ecosystem that has been produced environmental disparities globally (Wayland et al 2016). As created ecological inequities have been materialized assorted environmental dilemmas on the planet including water pollution and crisis.…”

Scaled Synthesis of Polyamine-Modified Cellulose Nanocrystals from Bulk Cotton and Their Use for Capturing Volatile Organic Compounds

“…Nanocellulose-based materials [ 2 ] have enjoyed wide applicability in this space, and represent a promising renewable feedstock for the development of sustainable platforms to address environmental needs [ 3 , 4 , 5 , 6 ]. More specifically, polyamine-decorated cellulose materials and related formulations have been explored for a number of environmental applications related to wastewater including the removal of anionic dyes [ 7 , 8 , 9 , 10 , 11 ], metal ions [ 11 , 12 , 13 , 14 , 15 ], and other environmental contaminants [ 16 , 17 ]. Despite the utility of nanocellulose for such applications, there are currently rather few raw material sources—wood pulp and marine tunicates—that provide access to CNCs at the kilogram scale [ 18 ].…”
