Pengaruh Agen Pengaktif-Kalium Hidroksida Berbantuan Irradiasi Gelombang Mikro Terhadap Kualitas Karbon Aktif Dari Kulit Jeruk Sebagai Adsorben

GLADYS MAY GRACE SIREGAR / 1603110055 - Nama Orang;

Biomass-based activated carbon has been developed as an alternative to overcome the accumulation of biomass waste such as peels. One way to overcome the problem is to make orange peel based activated carbon. This study was aimed to analyze the Potassium Hidroxide effect in synthesis of orange peel based activated carbon as a heavy metal adsorbent and to characterize the physical properties of the activated carbon. The activated carbon was made using the carbonization process, KOH activation and microwave irradiation. The KOH solutions used were varied using concentration of 2 M, 3 M and 4 M, and microwave irradiation power of 630 watt during 15 minutes. Surface morphology, level of crystallography, functional groups, and absorption were analyzed respectively using Scanning Electron Microscopy, X-ray Diffraction, Fourier Transform Infrared and Atomic Absorption Spectroscopy. Analysis of microstructure shows that the activated carbon is amorphous indicated by the presence of two narrow peaks of planes (002) and (100) at 2θ of approximately 20˚and 44˚. Analysis of FTIR shows the presence of O-H, C-H, C≡C, C=O, C=C, C-O in activated carbon. The surface morphology of activated carbon for the 4 M sample produced more pore number than sample of 3 M and 2 M and also supported by higest of layer height (Lc) is 19,288 nm for 4 M and atomic adsorption spectroscopy (AAS) analysis show that 4 M has the highest heavy metal adsorption 81,03% for Pb and 69,23% for Cu.
Keywords : Orange peel, activated carbon, potassium hidroxide, microwave irradiation, adsorption.
