Anti bacterial effect of activated carbons prepared from some biomasses available in North East India

ZnO-NPs/AC composite antibacterial agents with N-halamine glycinate functionalized silica-mesoporous silica coating for water disinfection

“…The SEM-image of ZnO-NPs/AC nanocomposite after introduction of ZnO-NPs into AC exhibits more smooth surfaces ( Fig. 9 ) [ 8 , 27 , 30 , 31 ]. The introduction of ZnO into activated carbon was evident from EDX analysis of ZnO-NPs/AC which showed the presence of 27.4 % for Zn and reduction of both C% from 78.9 % to 62.2 % and of O % from 17.4 % to 10.4 %.…”

“…The texture results of these materials including surface area, pore size and pore volume are analyzed for these materials and summarized in Table 3 . The impregnation of ZnO-NPs onto the AC surface contributes to slight decrease the surface area from 810 m 2 /g to 772 m 2 /g ( Table 3 ) [ 30 , 31 ]. After templating with ZnO-NPs/AC nanocomposite with silica spheres layer (SiO 2 ), the surface area has significantly decreased to ca.…”

Remediation of heavy metal polluted waters using activated carbon from lignocellulosic biomass: An update of recent trends

“…This could be due to the potential changes in the physical state of the aquatic ecosystem caused by the introduction of heavy metal contaminants. However, there is a general decrease in species diversity and distribution of aquatic plant organisms when they face the disruption in ecosystem balance and biological processes (Karlsson et al, 2010) (Das et al, 2019). This strong evidence have provided different perspectives in constructing a comprehensive understanding of the environmental hazard posed by heavy metal water contamination (Street, 2012) (Martínez-Cortijo and Ruiz-Canales, 2018).…”
