ABSTRACT
The needs for industrial wastewater treatment for heavy metal have been a
concern. Adsorption using hydroxyapatite (HAp) as adsorbent is one of the choice
to remove heavy metal content economically and efficiently. The objective of this
research is to study the effect of temperature and weight of adsorbent in
adsorption as well as determine adsorption equilibrium model in the lead ion
adsorption using Langmuir, Freundlich, and Temkin model. Lead (Pb2+) solution
of 5 ppm was added with 0.9 gram, 1.0 gram, and 1.2 gram of HAp in a beaker
glass and stirred with stirring rate of 300 rpm and temperature variation of 30°C,
40°C, dan 50°C. Solution samples was taken every 10 minutes until equilibrium
and and analyzed for the remaining Pb2+ using ICP-OES instrument. The results
showed that the increase of temperature reduce the rate of Pb2+ adsorption and
increased of the weight of adsorbent increase the percentage of adsorption. The
equilibrium time of lead ion adsorption is 50 minutes, with optimum condition
obtained on 30°C and hydroxyapatite adition 1.2 gram. Adsorption capacity on
the optimum condition is 1.1523 mg/g. It was also found that the Temkin
equilibrium model adequately describes the variation observed in this experiment.
Keywords: hydroxyapatite, adsorption, adsorpsion equilibrium model, lead (Pb2+)
