Pemanfaatan Zeolit 4A yang Disintesa dari Fly Ash Sawit sebagai Adsor-be Logam Fe
Abstract: Zeolite 4A has the
potential absorption of heavy metals Fe. It synthesized from flyash of palm, reactant
materials used in the synthesis of zeolite 4A is the sodiumsilicate and sodium
aluminate. Sodium silicate solution made from fly ash melt 25grams of oil and
62,5 g NaOH dried at a temperature of 500 °C for 5 hours. Themethod that being
used in the Fe metal adsorption process is a batch method. Thisresearch begins
with the equilibrium curve to determine the optimum contact time.Analysis of
adsorption results performed by AAS. The parameters used in thisresearch is the
first concentration of 100 ppm, the stirring speed of 150 rpm, a doseof 1 gram
of zeolite 4A, the variation in pH of the solution (4, 5, 6, 7 and 8) and
thetemperature (30, 40, 50, 60 and 70 °C). The results showed that the time to
achievethe equilibrium state in 4 hours, with the highest percentage of Fe
absorbed 98,0%at pH 6 and room temperature (≈ 30 °C).
