| Summary: | Empat biojisim berasaskan kelapa sawit yang merupakan pelepah kelapa sawit
(OPF), kulit batang kelapa sawit (OPB), daun kelapa sawit (OPL) dan tandan buah
kosong (EFB) telah diuji secara mod kelompok bagi penyingkiran Pb (II) dan Fe (III)
dari tiga larutan akua (individu dan dwilogam). Eksperimen tersebut telah dijalankan
pada julat pemboleh ubah: pH (2-12), saiz perjerapan-bio (200 µm-1400 µm), dos
(0.25 g/L-1.75 g/L) dan waktu sentuh (5 min-80 min).
Four oil palm-based biomasses which were oil palm frond (OPF), oil palm bark
(OPB), oil palm leave (OPL) and empty fruit bunch (EFB) were examined in batch
mode for removal of Pb (II) and Fe (III) from 3 different aqueous solutions (2 single
metal solution and bimetal). The experiments were done in certain ranges of
variables: pH (2-12), biosorbent size (200 µm-1400 µm), dosage (0.25 g/L-1.75 g/L)
and contact time (5 min-80 min). Oil palm bark (OPB) showed the highest
adsorption efficiency of 80 % and 78 % for lead and iron in bimetal solution,
respectively, and 79 % for lead solution and 77 % for iron solution, because OPB had
the higher surface area and pore volume in compare with other biosorbents. |
