Sintesis Adsorben Magnetik Fe3o4/Karbon Aktif Berbasis Pelepah Kelapa Sawit (…

SUMMARY Synthesis of magnetic activated carbon adsorbents has been successfully carried out on a laboratory scale. Activated carbon was made from palm frond biomass (OPF) by carbonization in a furnace at 600°C for 1 hour and chemically activated using KOH activator with a weight ratio of charcoal and KOH (1:3) which is then calcined at 800°C for 30 minutes. The preparation of magnetic adsorb…
