Pengaruh Jenis Aktivator Terhadap Penyerapan Ion Logam Pb2+Oleh Kulit Buah Matoa (Pometia pinnata)

Abstract

the effect of activation types on the biosorpsion of pb 2+ metal ions by matoa peel (Pometia pinnata) has been done. The purpose of this study was focused on the effect of the type of activator on the biosorpsion of pb 2+ metal ions by the matoa peel (Pometia pinnata) with chemical activation to determine the technical and condition of the activator according to the matoa peel which can be used as a Pb 2+ ion biosorbent. The method used is the batch method. The variables in this study are variation in the type of activator namely HCl, NaOH and KCl which will be characterized using the FTIR and AAS. The results showed that 0.1 M HCl was the best activator for matoa peel which gave a more optimal effect on the absorption of pb 2+ in the water, which was indicated by a decrease in %T of functional groups -OH, -CH and C-O which played an important role in the biosorption process and based on AAS results showed that the highest Pb 2+ biosorption capacity compared to other activators was 0.6462 mg/g with a % biosorption of 80.6239%.
