ABSTRACT
Pollution by mercury dissolved in aqueous
media causes a crucial problem for health and environment. In
this study, activated carbon from Bambusa vulgaris var. striata
was produced by chemical activation using NaOH for mercury
adsorption. The effects of mercury initial concentrations namely
50 and 100 mg/L on the breakthrough characteristics of the adsorption
process were defined. The mechanism of the adsorption process
through the fixed-bed column was fitted to the Thomas model. The
activated carbon was characterized by scanning electron microscopy
and energy-dispersive X-ray spectroscopy. The adsorption study
with a continuous system and using the Thomas model showed that
the highest adsorption capacity (q0) of mercury ions is 218.08 mg/g. It can be concluded that
activated carbon from Bambusa vulgaris var. striata
has a great potential to act as an adsorbent to remove mercury
from water.

ABSTRAK
Pencemaran merkuri terlarut dalam air
menyebabkan masalah kesihatan kritikal dan mencemarkan alam sekitar.
Dalam kajian ini, karbon teraktif daripada Bambusa vulgaris var. striata
dihasilkan melalui pengaktifan kimia menggunakan NaOH untuk
penjerapan merkuri. Kesan kepekatan merkuri awal iaitu 50 dan
100 mg/L ke atas kejayaan proses penjerapan telah ditakrifkan.
Mekanisme proses penjerapan melalui kolum lapisan tetap telah
disesuaikan dengan Model Thomas. Karbon teraktif yang dicirikan
melalui mikroskopi imbasan elektron dan spektroskopi serakan tenaga
sinar-X. Kajian penjerapan dengan sistem yang berterusan dan menggunakan
Model Thomas menunjukkan kapasiti penjerapan tertinggi (q0) ion
merkuri adalah 218.08 mg/g. Maka disimpulkan bahawa karbon teraktif
daripada Bambusa vulgaris var. striata berpotensi
besar untuk bertindak sebagai penjerat untuk mengasingkan merkuri
daripada air.
