EFEKTIVITAS PENJERAPAN DAN DAYA JERAP ADSORPSI ION TIMBAL (Pb2+) MENGGUNAKAN KARBON AKTIF BUAH BINTARO (Cerbera manghas)

---

Lead ion (Pb2+) is one of the heavy metals found in industrial waste from
metallurgy, mining, battery plating, petroleum refining and others. The maximum
recommended level of lead ions (Pb2+) in waste according to the Decree of the
Minister of Environment Number 5 of 2014 is 0.1 mg/L. Bintaro fruit has the
potential to be used as activated carbon because the lignin content in bintaro fruit
is almost the same as coconut shell which is widely used as raw material for
activated carbon and used as an adsorbent. This research studied the effect of
contact time and the amount of bintaro fruit activated carbon adsorbent on the lead
ion (Pb2+) adsorption process, with the parameters of adsorption power and
effectiveness of bintaro fruit activated carbon adsorbent. The research stage begins
with the preparation of bintaro fruit samples with a pass size of 100 mesh, then
activated with 15% H3PO4 for 24 hours. The adsorbent characteristics of bintaro
fruit activated carbon obtained contain 7.5% moisture content, 6% ash content, and
1142.1 mg/g iodine absorption capacity, this has met the characteristics of
activated carbon according to SNI 06-3730-1995. The adsorption process was
carried out at a variety of adsorbent masses of 10, 15, 20 g, contact time for 30, 60,
and 90 minutes with a stirring speed of 90 rpm, and a lead ion (Pb2+) adsorbate
concentration of 10 mg/L. The results obtained optimal adsorption power at a
contact time of 90 minutes with an adsorbent mass of 10 g amounting to 0,0423
mg/g and the highest adsorption effectiveness of 97,13 % at a contact time of 90
minutes with the amount of activated carbon adsorbent of 20 g bintaro fruit.
Keywords: adsorption, adsorbate, bintaro fruit, sorption capacity, effectiveness,
