“…Similar typical peaks were observed from the spectra of untreated and ultrasonic-treated IDF, including peaks around 3,400, 2,917, and 1,030/cm for O-H, C-H, and C-O-C vibrations, respectively (Gupta, Saleh, Pathania, Rathore, & Sharma, 2015;Kumar et al, 2012;Ma & Mu, 2016a). It can be observed that the untreated IDF had a characteristic absorption peak at 1,603/cm, which would be more probably attributed to the aromatic C5C stretch of aromatic rings (Sun, Xu, Sun, Fowler, & Baird, 2005).…”

The aim of this study was to investigate modification of insoluble dietary fiber (IDF) from garlic straw with ultrasonic processing technology. The functional, physicochemical, and structural properties were evaluated. Based on the uniform design (UD) method, initial temperature of 45 °C, ultrasonic power of 535 W, and time of 41 min were considered as the optimum ultrasonic conditions for preparation of IDF with good in vitro hypolipidemic ability. Ultrasonic‐treated IDF exhibited better functional and physicochemical properties than untreated IDF with significant difference (p < .05). Structural analysis from scanning electron microscope and Fourier transformed infrared spectroscopy indicated that ultrasonic treatment destroyed the microstructures of IDF from garlic straw, resulted in the honey‐comb network structure and increased hydrophilic groups, which illustrated the good functional and physicochemical properties. Practical applications With the trend toward increased consumption of garlic bulb, millions of tons of straw are generally discarded every year. The productive use of such by‐products as garlic straw could offer substantial economic benefits. In this work, ultrasonic technology was chosen for the modification of insoluble dietary fiber (IDF) from garlic straw. Uniform design technique helped us to get the optimum ultrasonic conditions for preparation of IDF with good in vitro hypolipidemic ability. The functional and physicochemical properties of garlic IDF were significantly influenced by ultrasonic pretreatment. The positive effect of ultrasound and application of the statistical model may be useful for functional modification and utilization of dietary fiber from garlic straw.

A B S T R A C TThe nanocomposite pectin thorium(IV) tungstomolybdate (Pc/TWM) has been prepared by incorporating pectin biopolymer within thorium(IV) tungstomolybdate, precipitated at 80˚C. The synthesized nanocomposite material was characterized using scanning transmission electron microscopy, transmission electron microscopy, scanning electron microscopy, X-ray diffraction analysis, and Fourier transform infrared spectroscopy. The binary mixture separations of heavy metal ions have been performed proficiently on the columns of Pc/TWM. The synthesized nanocomposite was exploited for removal of malachite green from the aqueous system under two set of conditions. The synergistic/adsorptional photocatalysis conditions were found to be more efficient than equilibrium adsorption followed by photocatalysis in the dark. The Pc/TWM also showed promising antibacterial activity against the bacteria, Staphylococcus aureus. Thus, the nanocomposite material can be used as an adsorbent for the remediation of harmful metals and dye pollutants from wastewater.

“…Owing to the abundant functional groups and large surface area of GO, the hydrogel exhibited high adsorption capacity for MB. Sharma et al used cellulose acetate as a frame to prepare a tin(IV) phosphate composite for photodegradation of MB in wastewater under irradiation by sunlight . Owing to the high ion‐exchange capacity and photocatalytic activity of the tin(IV) phosphate nanocomposite, the composite simultaneously absorbed and photodegraded MB under sunlight irradiation.…”

Water pollution, a worldwide issue for the human society, has raised global concerns on environmental sustainability, calling for high-performance materials for effective treatments. Since the traditional techniques have inherent limitations in treatment speed and efficiency, nanotechnology is subsequently used as an environmental technology to remove pollutants through a rapid adsorption and degradation process. Therefore, here, various adsorbent and photodegradation composite materials leading to effective water remediation are summarized and predicted. Notably, recent advances in simultaneous adsorption and photodegradation micro-nanocomposites are outlined. Such materials can not only completely adsorb and remove contaminants, but the micro-nanocomposites can also be directly reused without further treatment. Finally, the future development of this unique system is discussed.
