“…30 It is one of the most consumable dyes used in industries, which is used for dyeing cotton, paper, wool, and silk. [31][32][33][34] These industries release their effluents, containing a significant amount of MB dye, into natural water bodies which is becoming an increasing threat in terms of both aesthetic and toxicological concerns. [35][36][37] Due to its non-biodegradable, toxic and carcinogenic nature, the presence of MB dye in water is a serious threat to human health.…”

“…59 The grafted material with good performance not only can prevent food from spoiling and prolong the shelf life, but it can also be well biodegraded, which is expected to be used in biomedicine and food packaging. Moreover, Mijinyawa et al 60 used taro mucopolysaccharides as an adsorbent to explore its adsorption performance for methylene blue in water. It was found that, under certain conditions, the removal rate using taro polysaccharides could reach 72.35%, which indicated that CEM can be used as a green and economic adsorbent.…”

Taro, a staple food for residents in Africa and parts of Asia, is an important source of carbohydrate. China has abundant taro resources. Taro contains polysaccharide, vitamins, minerals and other substances. Taro polysaccharides, as a significant active ingredient in taro, are mainly composed of monosaccharide units such as glucose, galactose, arabinose, mannose, and so on. Taro polysaccharides have antioxidant, lipid‐lowering, and immunomodulatory effects. In today's world, people are interested in food containing natural ingredients, which stimulates the potential of taro polysaccharides in the food, pharmaceutical, medical, and other fields. Herein, the extraction and purification, structural characterization, functional activity, and application of taro polysaccharides are reviewed to strengthen the cognition of taro polysaccharides. It provides references for further research and development of taro polysaccharides. © 2022 Society of Chemical Industry.

Super Effective Removal of Toxic Metals Water Pollutants Using Multi Functionalized Polyacrylonitrile and Arabic Gum Grafts

Super adsorbent polymers can be considered to be a very efficient solution for wastewater treatment. In general, their adsorption capacities depend on the type and amount of the functional groups present on the surface of the polymers, while their economic value is affected by their cost. Therefore, this study aims to understand the effect of multi-functionalization of cheap Arabic gum on the adsorption capability toward heavy metals. Graft copolymers of polyacrylonitrile (PAN) onto Arabic gum (AG) were prepared in aqueous solution using (KMnO4/HNO3) as a redox initiator. Chemical modification of the graft copolymer was carried out by reaction with hydrazine hydrochloride followed by hydrolysis in the basic medium. The modified graft product was characterized by various techniques, such as Fourier transform infrared spectroscopy (FTIR), elemental analysis, scanning electron microscope (SEM), and X-ray powder diffraction (XRD). The modified graft copolymer was used to adsorb Pb2+, Cd2+ and Cu2+ from their aqueous solutions using batch extraction. Different parameters influence the uptake behavior, including contact time, pH, and the initial concentration of the metal ions; all of these were investigated. The kinetics were investigated using the pseudo first order and pseudo second order, and the equilibrium data were analyzed using the Langmuir and Freundlich model. The modified graft product showed the superadsorbent capacity to obtain maximum values (Qmax) 1017, 413 and 396 mg/g for Pb2+, Cd2+ and Cu2+, respectively. Acid treatment with 0.2 M HNO3 resulted in 96%, 99% and 99% metal recovery for the Pb2+, Cd2+ and Cu2+, respectively. This indicates the recyclability of product for further usage upon drying between treatments.
