摘要

从蚕茧中化学提取并纯化了蚕丝纤维素(SF)的蛋白质纤维。它被用作与胶原蛋白(Col)和透明质酸(HA)形成水凝胶的增强纤维。氯化钙(8 wt.%)被用作交联试剂,用于合成基于 SF/Col/HA 的水凝胶复合材料。傅立叶变换红外光谱证实,β-片状结构中酰胺 II 的平面弯曲导致 N-H 伸展。XRD 分析证实了 SF/Col/HA 水凝胶复合材料的结晶性。扫描电子显微镜显示了相互连接的三维多孔结构。这些多孔结构可作为吸附介质的储存库。水凝胶复合材料在 250 °C 下具有热稳定性。低沸点结合溶剂蒸发温度、玻璃化转变温度和降解温度分别为 102 ℃-105 ℃、298 ℃-300 ℃ 和 524 ℃-545 ℃。孔隙率和凝胶部分的范围分别为 60%-80% 和 90%-95%。水凝胶复合材料在 1 小时内迅速膨胀,随后达到平稳状态。抗压强度为 4-6 兆帕。作为吸收介质,水凝胶很容易通过静电作用吸附铅离子。它们可用作吸附重金属的储层。

Synthesis and characterization of carbonaceous materials for lead adsorption

Synthesis and characterization of carbonaceous materials for lead adsorption
Protein fibers derived from silk fibroin (SF) were chemically extracted and purified from cocoons. It was used as a reinforced fiber for hydrogel formation with collagen (Col) and hyaluronic acid (HA). Calcium chloride (8 wt. %) was employed as a crosslinking reagent to synthesize the SF/Col/HA-based hydrogel composite. FTIR spectroscopy confirmed the presence of N–H stretching due to the plane bending of amide II in the β-sheet structure. XRD analysis confirmed the crystallinity of the SF/Col/HA-based hydrogel composite. Scanning electron microscopy revealed three-dimensional porous structures with interconnected pores. These porous structures can serve as reservoirs for storing adsorbent media. The hydrogel composite was thermally stable at 250 °C. The low-boiling bound solvent evaporation temperature, glass transition temperature, and degradation temperature were 102 °C–105 °C, 298 °C–300 °C, and 524 °C–545 °C, respectively. The ranges of porosity and gel fraction were 60 %–80 % and 90 %–95 %, respectively. The hydrogel composite was rapidly swollen within 1 h, reaching a plateau afterward. The compressive strength was 4–6 MPa. As absorbent media, hydrogels can easily adhere to lead ions via electrostatic interactions. They can be used as reservoirs for the adsorption of heavy metals.
