| dc.description.abstract | Adsorbent from the fur shells could be used to adsorb heavy metal ions such as
Cd(II) and Pb(II). This is shown from the results of the analysis of metal adsorption
by measuring the percentage entrapment values. This research was aimed to identify
factors - factors that influenced the making of adsorbent, determine the nature and
characteristics of the fur shells and to know how much was the compound had been
adsorbed as well as the value of Langmuir and Freundlich Isotherm. Materials -
materials used include fur shells, aquadest, and a solution of metal Cd(II) and Pb(II).
Variables in this research was the activation temperature, the amount of adsorbent,
the concentration of the metal solution was used and the time until equilibrium. This
research was began with fur shells reduction to the size of 140 mesh, and then
activation thermal at a temperature 110ᴼC, 500ᴼC and 800ᴼC in the furnace.
Furthermore, the analysis process by performing adsorbent characterization using
BET equipment, measure its density, moisture content and ash, as well as adsorbed
adsorbent 500ᴼC with a solution of metal and measured the remaining solution by
AAS equipment. The result showed that adsorbent activated at temperatures 110ᴼC,
500ᴼC and 800ᴼC had surface area 725.43; 807.94; and 803.822 m2
/kg. Density was
inversely proportional to the activation temperature, the value of moisture content
and ash was the specified with the value by SNI. Adsorbents activated at
temperatures 500ᴼC better followed Freundlich Isotherm equation. | en_US |
