“…On comparing the values obtained, it was clear that the removal of Cr was the highest in neutral medium than the acidic medium and was the least at basic medium. As stated by Arthanareeswaran et al (2007), the rejection increases as the pH of the chromium solution increases and chosen an optimum pH of Fig. 8 Physicochemical parameters of the treated effluent at pH = 7 Fig.…”

“…The membrane was prepared by phase inversion process (Witte et al 1996;Loeb and Sourirajan 1963;Arthanareeswaran et al 2007;Nath 2008;Velu et al 2011) which is a well-known technique to prepare asymmetric membranes. The deaerated polymeric solution was casted on a glass plate, and the thickness of the membrane was maintained about 0.2 mm approximately.…”

The present study was aimed to fabricate a novel ultrafiltration membrane using cellulose acetate, nanochitosan, and polyethylene glycol of ratio 1:2:2 by phase inversion method. Analytical techniques such as Fourier transform infrared spectroscopy (FTIR), X-ray diffractometer (XRD), and scanning electron microscopy (SEM) have been employed to characterize the prepared membrane. FTIR and XRD results revealed the formation of blended membrane with increased amorphous nature. SEM studies exhibited the rough surface with numerous pores. The prepared membrane was also characterized for its ultrafiltration performance by membrane compaction, pure water flux, water content, and porosity. The results showed that the membrane obtained a pure water flux of 25.32 l/m 2 h. The water content was found to be 24 % and a high porosity of 83 % was obtained which showed the membrane's high hydrophilicity and more porous nature. The main focus of the present study was toxic hexavalent chromium removal from tannery effluent using the prepared hydrophilic membrane, which causes various adverse effects. The effect of pH of the solution (viz., pH 5, 7, and 9), membrane thickness (0.1 and 0.2 mm), and the applied pressure (50 and 100 kPa) were studied which are the key factors in determining the efficiency of the prepared membrane in remediation of tannery effluent. The results showed high percentage removal of chromium at pH 7 using 0.2 mm thickness at 100 kPa. The physicochemical parameters of the tannery effluent were also found to be reduced.

“…The modification and functionalization of CMC also had the ability to remove protein. Metal ion separation and protein removal were also investigated using modified cellulose acetate membranes by Arthanareeswaran et al (2007b) . The millimeter-sized chitosan/CMC hollow capsules were prepared to remove three typical dyes such as MB, methyl orange (MO), and acid blue-113 (AB) by mixing and stirring positively charged chitosan and negatively charged CMC solutions under an electrostatic interaction ( Kong et al, 2020 ).…”

In recent years, faced with the improvement of environmental quality problems, cellulose and cellulose-based (nano) composites have attracted great attention as adsorbents. In this review article, we first report the recent progress of modification and functionalization of cellulose adsorbents. In addition, the adsorbents produced by the modification and functionalization of carboxymehyl cellulose are also introduced. Moreover, the cellulose-based (nano) composites as adsorbents are reviewed in detail. Finally, the development prospect of cellulose and cellulose-based (nano) composites is studied in the field of the environment. In this review article, a critical comment is given based on our knowledge. It is believed that these biomass adsorbents will play an increasingly important role in the field of the environment.
