“…The d 114/110 Cd measured for a range of geological standards were in good agreement with reported values. Common water hyacinth (Eichhornia crassipesas) can be used 131 as a biosorbent for Pb. By applying factorial design, SPE conditions were optimised at 0.02 g of dried and milled leaves as sorbent, with sample inlet and eluent (0.1 M HCl) ows of 5.6 and 6.8 mL min À1 , respectively.…”

“…Eichhornia crassipes has been seen as a useful or harmful plant in ecosystems. Almeida et al (2021) mentions that this plant causes serious problems and is therefore necessary to eliminate it from aquatic ecosystems which would have a huge environmental benefit. On the other hand, Ansari et al (2020) and Sharma et al (2021) suggest that because the quality of water is frequently altered by various organic and inorganic pollutants, various strategies have been developed to solve this problem.…”

In this paper, methacrylic acid (MAA) and 4-vinyl pyridine (4-VP) as functional monomers, ethylene glycol two methyl acrylate (EGDMA) as crosslinking agent, isopropyl alcohol as the solvent, prepared the Cu(II)-and Pb(II)-imprinted polymers(IIPs) submicron spheres by precipitation polymerization. The presence/absence of the template ion in the preparation of the imprinted polymer was confirmed by EDX spectroscopy, and the structure of the particles was investigated using IR, SEM and BET analysis. From different components of crosslinker/monomer(C/M) ratio analysis, C/M at 1:3 was the optimal ratio for preparing IIPs. Atomic absorption spectroscopy (AAS) was characterized the imprinted polymers absorption behavior. The results show that the maximum adsorption capacity of Cu 2+ and Pb 2+ -imprinted polymer were 26.9mg﹒g −1 and 25.3mg﹒g −1 , respectively. They also have good adsorption capacity and superior selectivity property for Cu 2+ and Pb 2+ in water, respectively. The selectivity factors (α) for Ni 2+ , Zn 2+ , Co 2+ and Fe 2+ were 16.5(Cu 2+ ) and 12.1(Pb 2+ ), 13.8(Cu 2+ ) and 16.2(Pb 2+ ), 10.8(Cu 2+ ) and 10.1(Pb 2+ ), 20.4(Cu 2+ ) and 20.7(Pb 2+ ), respectively. The regeneration experiment result demonstrates an excellent re-utilization property of these two type IIPs, after ten uses, the adsorption capacity can maintain above 60%.
