Optimasi Suhu Aktivasi Proses Pembuatan Arang Aktif Limbah Tulang Kambing

Abstract

Livestock waste, such as bone, has always been ineffectively exploited. Bones contain organic compounds that can be further processed into usable products such as charcoal and activated charcoal. This research, therefore, aims to identify the optimum temperature conditions suitable for the manufacturing process of activated charcoal from goat bone waste using thermal activation. The study uses a two-stage process which is carbonization and thermal activation. Activation temperatures used in the process were at a temperature of 500 °C, 600 °C and 700 °C for three hours. The results of the characteristics of activated charcoal thermally produced in this research met the Indonesian National Standard 06-3730-1995 about technical activated charcoal, and the optimum conditions were at an activation temperature of 500 °C. These characteristics include the values of the water content at 1.210%, ash content at 2.034%, absorption of iodine 926 mg/g, volatile matter of 0.434% and fixed carbon of 96.616%.

The Application of Goat Bone Waste Activated Charcoal As Manganese Heavy Metal Absorbent in Borehole Water

“…Several previous studies on the utilization of goat bone waste into activated charcoal using chemical activation, namely sulfuric acid with concentrations of 1N, 2N, and 3 N, reported were able to absorb Iod of 983 mg/g (Wardani & Rosa, 2018). Physically activated charcoal for 3 hours at 500 o C, 600 o C, and 700 o C was able to absorb iodine at 926 mg/g, 806 mg/g, and 768 mg/g (Wardani & Mirdayanti, 2019). Physically, bones have pores that can be used as activated charcoal because the pores found in goat bones can adsorb other substances to the surface of the bone pores and contain calcium hydroxyapatite (Euw et al, 2019).…”

Pengolahan Limbah Tulang Kambing Sebagai Produk Arang Aktif Menggunakan Proses Aktivasi Kimia dan Fisika

“…Arang aktif tulang sapi diaplikasikan sebagai bahan penyerap kromium heksavalen di dalam air (Ghanizadeh et al, 2012). Arang aktif berbahan baku tulang kambing mampu menyerap iodium sebesar 926 mg/g dengan menggunakan suhu aktivasi 500 o C selama 1 jam (Wardani and Mirdayanti, 2019).…”
