Sustainable electrochemical synthesis of natural starch-based biomass adsorbent with ultrahigh adsorption capacity for Cr(VI) and dyes removal

A starch based sustainable bio-hybrid composite for surface assimilation of methylene blue: preparation, characterization, and adsorption study

“…This is due to the flakes losing their crystalline structure and experiencing strong crosslinking, possibly by intercalation. 1,42,50 The lower intensity of the peaks obtained could be the result of the acidic environment employed while preparing the starch–HNT flakes. 1,42…”

“…Besides, the peaks found at 993 cm −1 , 918 cm −1 , and 867 cm −1 are exclusively for the C–O bond of the anhydroglucose ring. 44,48,50…”

“…1,48 On the other hand, HNT has strong crystalline peaks at 2q angles of 11.73°, 20.01°, 24.93°, 26.40°, 35.49°, 38.10°and 62.55°. 21,25,34,49,50 Additionally, the peak at 11.73°is typical for the tubular architecture of HNT and corresponds to the (001) plane. 48 However, the diffraction pattern for the binary mixture reects the dominance of HNT, with few weak peaks for starch.…”

“…This is due to the akes losing their crystalline structure and experiencing strong crosslinking, possibly by intercalation. 1,42,50 The lower intensity of the peaks obtained could be the result of the acidic environment employed while preparing the starch-HNT akes. 1,42 Scanning electron microscopy (SEM) helps to understand the morphological changes that take place within the samples as they segue themselves into a hybrid material.…”

Efficient Photocatalytic Dye Degradation and Bacterial Inactivation by Graphitic Carbon Nitride and Starch-Doped Magnesium Hydroxide Nanostructures

“…In recent years, the continuously developing population and corresponding environmental deterioration caused by a substantial concentration of dyes, heavy metals, and microorganisms have become a serious concern of society and academia. 1 In developing countries, fast developments of industries give rise to industrial effluent removal into water bodies without appropriate precautions, endangering aquatic life and plant life. Specifically, organic dyes are toxic, carcinogenic, and potentially mutagenic, yet researchers do not break them down in the environment because of their structures.…”
