Karakteristik Komposit Adsorben Berbahan Spent Bleaching Earth (Sbe) Dan Spent Mushroom Substrate (Sms) Terhadap Penyisihan Logam Cu2+

---

ABSTRACT
Copper (Cu2+) is one of the heavy metals that is toxic to aquatic organisms and
humans, copper tends to be dangerous when the concentration is more than 0.5
mg/L. To reduce the content of copper can be done by the adsorption process. Spent
bleaching earth (SBE) and spent mushroom substrate (SMS) were used as
adsorbents by combining them into composites to increase the adsorption ability.
The purpose of study is to determine the characteristics, stability, surface area,
calculate the capacity and efficiency of absorption and determine the functional
groups of the adsorbent composite. Characterization process used the proximate
test method with a surface area using iodine method and determines the functional
groups used FTIR method with composition variation of SBE-SMS 25: 75 %; 50:
50 %; 75: 25 %; 0: 100 %; and 100: 0 %. The best characteristics are found in the
variation of the composition of SBE-SMS 25:75% with the highest adsorption
capacity of 2.9945 mg/g in 3 grams mass and there are hydroxyl groups, ketone
groups, phosphate groups, and siloxane groups that act as adsorbers of Cu2+ ions.
Keywords : adsorbent, composite, copper, spent bleaching earth, and spent
mushroom substrate.
