| dc.description.abstract | Therefore, it was necessary to develop nano-adsorbents for the remediation of polluted
water, this process was carried out by combining Chitosan (C)-Magnetic (M)-activated
Carbon (C) materials. The activated carbon used results from the synthesis of
nanostructures from banana peel waste, while the magnetic carbon is from Fe3O4. This
research involves an experimental method with coprecipitation through several stages:
(i) Synthesis of Fe3O4 nanoparticles by the coprecipitation method; preparation of
chitosan solution (ii) synthesis of activated carbon nanostructures extracted from
banana peel waste by milling (iii) a combination of the three materials (iv)
characterization with SEM/EDX, XRD, FTIR, BET, PSA, TGA, and AAS to test the
performance of the material against polluted water. The performance results for the
concentration (mg/g) of heavy metal ions and their percentage adsorption are Zn
(4894,22; 92,43 %), Fe (5849,4; 95,44 %), Mn (5162,4; 89,54 %), and Pb (468,2; 84,38
%) for the most effective nanoadsorbent sample (S4) of CMC material with a ratio of
1:2:2 using the Langmuir model with an optimum time of 210 minutes. KMK
nanoadsorbent is effective in remediating water polluted with heavy metals Pb, Mn,
Zn, and Fe which meets environmental health quality standards for water media for
sanitation hygiene purposes. | en_US |
