“…Eficiencia de bioadsorción de vegetales silvestres sometidos a metales y metaloides contenidos en agua superficial 97 contrastando con los autores que refieren al respecto, el terreno para una óptima producción de pastos requiere un pH de entre 6 y 6,5, con suficientes nutrientes (Tejada, et al, 2015); para el agua de riego agrícola va de 6.0 a 9. V. 2009) siendo un parámetro muy importante en la evaluación de aguas subterráneas, si se encuentra en altas concentraciones producirá un medio oxidante y si se encuentra en bajas concentraciones producirá un medio reductor (Dusi et al, 2022).…”

La contaminación de aguas superficiales procedentes de cabeceras de cuenca de zonas mineras con metales y metaloides, es un problema ambiental que debe ser abordado, a través de la investigación científica, para minimizar sus impactos y sus efectos. El objetivo de este estudio fue determinar y evaluar la eficiencia de bioadsorción de vegetales silvestres en la eliminación de metales y metaloides presentes en agua superficial proveniente de cabeceras de cuencas del centro poblado de San Pedro de Mimosa Ccochaccasa en la provincia de Angaraes, Huancavelica - Perú. Esto implica utilizar plantas silvestres como agentes de absorción para reducir la concentración de contaminantes en el agua, en este caso, metales y metaloides provenientes de la actividad minera. El estudio se llevó a cabo de manera experimental, prospectiva, transversal y analítica, lo que corresponde al nivel de investigación aplicativa. El muestreo se realizó de manera intencional a criterio de los investigadores. La eficiencia de adsorción para la planta chilca fue 16.28% de As, 28.60% de Cd y 27.31% de Pb, para diente de león 28.70% de As, 79.33% de Cd y 28.75% de Pb y a cascara de tuna 48.39% en As, 46.38% de Cd y 45.23% de Pb. El resultado es significativo, diente de león con 45.59% supera a cascara de tuna en 39.44% y chilca en 33.44%. Se llevó a cabo un análisis estadístico con método Tukey y se determinó que no existe una diferencia significativa en las eficiencias de bioadsorción entre las plantas. Los resultados podrían ser aprovechados para diseñar sistemas de tratamiento de aguas basados en la bioadsorción utilizando estas plantas, ofreciendo una alternativa sostenible y económica a los métodos convencionales de remoción de contaminantes.

“…The sericin wraps the SF. SF is obtained from a degumming process to remove the sericin and is the component used for textiles, while sericin is usually discarded as waste [3]. Today, the use of silk proteins has expanded from the textile field to many new fields, including environment remediation, bioengineering, and intelligent electronics, due to their outstanding mechanical properties, biocompatibility, biodegradability, and processibility [4,5].…”

“…Silk proteins adsorb heavy metal ions through chelation and electrostatic interactions. SF or sericin are often made into films, beads, and particles, or combined with other ecofriendly adsorbent materials using a mild process outlined in studies on their adsorption performances [3,36,37]. The silk-based composite adsorbents not only exhibit better adsorption efficiency compared to silk, but also maintain the same characteristics as silk, including selective adsorption, durability, and biodegradability [36,38].…”

Silk secreted by Bombyx mori L. silkworm has become one of the most important biomaterials, due to its excellent biocompatibility, controllable biodegradability, superior processability, and unique mechanical properties. Silk fibroin and sericin, as the two components of silk, contain abundant polar functional groups, and thus can bind metal ions through electrostatic interaction and chelation. Based on this binding, silk proteins not only can be used to fabricate ecofriendly and efficient adsorbents to remove heavy metals from waterbodies, but also can synthesize metal nanostructures (nanoparticles or nanoclusters) to form silk/metal composites with amazing optical or electrochemical characteristics. This binding also can be manipulated to optimize silk’s performance. This review focuses on discussing and summarizing advances in the use of silk fibroin and sericin for heavy metal ion-contaminated water remediation, biosensing materials, and electrochemical materials from the perspective of the interaction between silk proteins and metal ions. The performance enhancement of silk using metal ions is also analyzed. Moreover, the silk proteins’ interactions with metal ions and related structural features that contribute to the above sustainable applications are illustrated to lay a theoretical foundation. This review will favor the expansion of the applications of silk in both the traditional textile field and new biomaterials.

“…Several studies have worked on using discarded SS to remove heavy metal ions from water. Dusi et al [ 23 ] reported the use of sericin–alginate particles to remove Cu(II) ions from aqueous solutions, and their maximum adsorption capacity was 87.27 mg/g. Singh et al [ 24 ] showed that prepared chitosan–sericin conjugates could effectively remove Cr(VI) ions from water, with a maximum adsorption capacity of 139 mg/g.…”

Sericin is a by-product of the silk industry. Its recycling contributes to environmental protection and the sustainable development of the cocoon silk industry. In this paper, on the basis of realizing sericin enrichment in solution, the Cu(II) adsorption capacities of sericin-derived carbon (SC), prepared at different pyrolysis temperatures, were studied. SC was characterized using scanning electron microscopy (SEM) and the zeta potential. The effects of the initial concentration of Cu(II), pH, adsorption temperature, and contact time on the adsorption process were evaluated, followed by an investigation of the mechanism of Cu(II) adsorption by SC. The results showed that SC has a porous structure that provides sites for Cu(II) adsorption. The maximum adsorption capacity of Cu(II) onto SC1050, 17.97 mg/g, was obtained at an adsorption temperature of 35 °C and a pH of 5.5. In addition, the pseudo-second-order kinetic model and Langmuir isotherm model correctly described the adsorption process of Cu(II) onto SC1050. Therefore, SC can act as a potential adsorbent for removing Cu(II) from water. This study helps promote the effective use of cocoon silk resources.
