| description | Preparation of activated carbons from sago wastes were investigated in this study. The raw
material of sago wastes was first pyrolysed in a pyrolysis reactor in inert condition for a total
of 3 minutes. The samples was subjected with N2 gas for 30 minutes to get an inert
environment inside the quartz reactor before exposing the samples to microwave action for
at least 3 minutes. The char sample was added with 50 % H2SO4 and 50% Na2SO4 for
activation. The adsorption rate has been studied under several parameters like adsorbent
dosage, initial concentration, pH and agitation time with three types of heavy metals, which
include Lead, Pb(II), Copper, Cu(II) and Chromium, Cr(II). The adsorption parameters
influenced on the adsorption rate were analyzed using Langmuir and Freundlich isotherm.
The characteristics of the sago waste activated carbon were also investigated by studying the
moisture content, ash content, volatile matter content, fixed carbon, surface morphology
(SEM) and functional groups (FT-IR). Batch Adsorption test showed that the adsorptions of
Pb(II), Cu(II) and Cr(II) metal ion differ for each parameter. According to the evaluation
using Langmuir equation, the monolayer adsorption capacity obtained were 0.4464 mg/g,
0.0371 mg/g and 3.5714 mg/g for Pb(II), Cu(II) and Cr(II) respectively. |
