Enhanced adsorption of synthetic dyes from aqueous solution by a semi-interpenetrating network hydrogel based on starch

Synthesis, characterization and adsorption studies of an acrylic acid-grafted sodium alginate-based TiO2 hydrogel nanocomposite

“…The adsorption capacities of different adsorbents for MV are listed in Table 2. It can be found that SA-g-PAA/TiO 2 absorbent is more efficient compared to those reported in previous literature (Bhattacharyya and Ray, 2014; 2013; Ghorai et al, 2014;Liu et al, 2011;Maity and Ray, 2014;Mandal and Ray, 2014;Mittal et al, 2015;Tian et al, 2010;Xu et al, 2011). This result indicates that SA-g-PAA/ TiO 2 hydrogel nanocomposite can be regarded as promising material for the MV removal from aqueous solution.…”

Facile fabrication of magnetic carboxymethyl starch/poly(vinyl alcohol) composite gel for methylene blue removal

“…In recent year, numerous attempts have been made to develop low cost and effective adsorbent. In this regard, increasing attention was paid on agricultural residues (e.g., rice husk [12] and wheat shell [13]) and natural polymers (e.g., chitosan [14,15] and cellulose [16,17]) because they are easy-available, renewable, and biodegradable.…”

Preparation and Characterization of Environmentally Friendly Controlled Release Fertilizers Coated by Leftovers-Based Polymer

“…In the XRD pattern ( Figure 2), a broad peak of between 2θ = 10-30° was observed, which suggested an amorphous structure in SF. In addition, a strong peak was found in SF at 20.4°, which was caused by intramolecular and intermolecular hydrogen bonds between OH groups in starch, suggesting that SF had a crystalline domain characteristic of a starch substrate [29]. The XRD pattern of FPU coating in Figure 2 exhibited an amorphous structure.…”
