Another cyclodextrin and GO-based grafted composite was prepared by Wang S. and coworkers for phasing out dye contaminants from wastewater. In this study, the selected targeted dyes are fuchsin acid, methylene blue, and methyl orange. The reason for adsorption is the inclusion complex formation of dye with the cyclodextrin moiety. The high adsorption of fuchsin acid may attribute to the complementary molecular size of the fuchsin acid with the size of the inner cavity of cyclodextrin as compared to other dyes studied. The low polarity of methylene blue dye was responsible for its high adsorption as compared to methyl orange (Wang et al., 2015a). The data focused on the adsorption of methyl orange dye onto polysaccharide–GO-based composites have been compiled in Table 12.6.

The textile industry is the major consumer of dye and also a major source of discharge of dye wastewater. Dye water reduces the ability of photosynthesis which can affect whole aquatic ecosystems. Incomplete dye decomposition by bacteria (anaerobically) through toxic amine in sludge can also disrupt aquatic life. Potable water sources on the planet are limited, yet they are still insufficient.[1] Fuchsine dye can cause respiratory illness such as nasal inflammation and chronic contamination and can lead to bladder tumors. The disposal of wastewater and solid waste caused by the overuse of Fuchsine dyes pollutes the environment.[2,3] Jia Li et al. (2014) have used ZnFe2O4 magnetic hollow fibers for acid Fuchsine removal with a significant adsorption capacity of 150.37 mg/g. Mohammadine El Haddad (2016) successfully utilized biomass waste material from a mussel shell for the adsorption of BF. Likewise, Gupta et al. studied the feasibility of ‘bottom ash’ and ‘deoiled soya’ for BF uptake and the percent adsorption was found to be 83.75 and 94.25%, respectively. Mohamed Kadari (2016) eliminated BF using functionalized Zn/Al-DDPA with 90% uptake efficiency. Similarly, investigation of the uptake capacity of activated carbon for BF from simulated water was found to be 98% in the research study of Liyi Ye (2011). Furthermore, the adsorption effectiveness of several metal nanocomposites toward various hazardous dyes has been documented.[4–8] Recently studied Mg, Zn, and Fe metal oxides for dye removal are selected and produced as MgZnFeO nanocomposites (MZFONCs) for the rapid and efficient adsorption of dye pollutants from industrial wastewater. In this study, Fuchsine dye is removed from the aqueous solution using MgZnFeO nanocomposites (MZFONCs).[9–12]
