Kinetika Adsorpsi Pada Penjerapan Ion Timbal Pb2+ Terlarut Dalam Air Menggunakan Partikel Hydroxyapatite

---

ABSTRACT
Ion metal of Pb2+ are one of the heavy metals can pollute water.
Concentration of ions Pb2+ can be removed by adsorption method. The purposes of
this research are to observe the effect of mass adsorbent and temperature in
adsorption of metal ions Pb2+ using adsorbant hydroxyapatite (HAp) and determine
a suitable adsorption kinetics model. Pb2+ solution 9,982 mg/L of 500mL where
mixed with variation of mass HAp (0.3 g, 0.5 g and 0.9 g) in a glass beaker while
stirred with rate 100 rpm at variation temperature (27, 40, and 50 oC).Pb2+ solution
was taken at a certain time, then the solution filtered and analyzed by atomic
absorption spectrophotometer (AAS). The result showed that the adsorption of
metal ions is pseudo second order reaction with the higher mass of adsorbant and
with lower temperature. In this research maximum constant value of adsorption
kinetic was 0.2758g/mg.min obtained with mass of adsorbent 0.9 g and temperature
of 27 oC. While minimum value of adsorption kinetics constant 0.0389 g/mg.min
obtained with mass of adsorbent 0.3 g and temperature of 50 oC.
Key Word: Adsorption, Hydroxyapatite, Kinetic, Timbale.
