ABSTRACT

Among various selenium (Se) species in water, Se(IV) poses a greater toxicity due to its unique structural characteristics. To address the contamination issue posed by Se(IV) more effectively, this study employed a hydrothermal synthesis method to create an inorganic metal material, specifically a Mg?Al layered double hydroxide (Mg?Al?CO3 LDH). Meanwhile, the organic material, silk fibroin (SF), was synthesized via a lithium bromide approach. Scanning electron microscopy (SEM) was utilized to characterize the morphology and structure of the fabricated materials, confirming the successful preparation of both Mg-Al-CO3 LDH and SF as adsorbents.Through adsorption experiments, their efficacy in removing Se(IV) was investigated, with results revealing that both Mg?Al?CO3 LDH and SF demonstrate notable adsorption capacities for Se(IV). Specifically, the adsorption capacity of LDH towards Se(IV) was measured at 29 mg/g, while SF exhibited a capacity of 16 mg/g. Notably, the two adsorbents synthesized in this research offer significant advantages: they are environmentally friendly, low cost and their synthesis procedures are straightforward, thereby showcasing high potential for the remediation of Se(IV) in its anionic form from contaminated aqueous environments.
