Biosorption of lead (II) from an aqueous solution using biosorbents prepared from water plants

Abstract: Due to its toxicity causing serious health problems, persistence in the environment and non-biodegradability, lead (Pb) is considered as one of the most harmful metals on earth. In this study, dried aquatic plants as sorbents including Nymphoides peltata (NP), Typha laxmannii (TL), and Eichhornia crassipes (EC) were examined and compared to discover the best biosorption for Pb. The effect of physical and chemical parameters including pH (2.0-5.5), sorbent dosage (1-5 g/l), metal concentration (20-100 mg/l), an… Show more

“…Heavy metals such as lead, copper, cadmium, zinc and nickel, are considered priority environmental pollutants, due to the toxicity that metal ions present in living organisms. After their release from various sources, such as industrial and agricultural activities, heavy metals are not degraded and they persist in the environment [1].…”

“…Los metales pesados, tales como plomo, cobre, cadmio, cinc y níquel, son considerados contaminantes ambientales prioritarios debido a la toxicidad que los iones metálicos presentan en los organismos vivos. Tras su liberación a partir de diversas fuentes, como pueden ser las actividades industriales y agrícolas, los metales pesados no son degradados y persisten en el medio ambiente (Tseveendorj et al, 2017). Actualmente se utilizan numerosas tecnologías para eliminar estos contaminantes de efluentes líquidos como la precipitación química, el intercambio iónico, los procesos de oxidación avanzados, la separación por membrana y la adsorción (Carolin et al, 2017).…”
