摘要

以硅酸钾(K2SiO3)为活化剂,研究不同的糖棕榈活化温度对棕榈束活性炭官能团的影响。化学活性炭的制作过程分为三个阶段,首先是准备阶段,将棕榈束准备成切割,洗涤和干燥,其次是在300℃- 400℃温度下约±8小时的碳化阶段和化学活化阶段。硅酸钾K2SiO3是一种新型活化剂,用于以2∶1的比例(K2SiO3:活化棕榈束)活化活性炭12小时,活化温度分别为600℃、650℃、700℃、750℃、800℃,活化时间为30分钟。利用傅里叶变换红外(FTIR)对棕榈束活性炭进行了表征。红外光谱分析表明,所制活性炭具有吸附模式,键的类型为C≡C (Alkuna)、C=C (Aromatic Rings)、C- h (Alkanes)、Si-O和C- h (Alkanes)。结果表明,650℃、700℃和750℃是棕榈束活性炭较好的活化温度,700℃时红外吸收最大。

Analisis Variasi Temperatur Aktivasi terhadap Gugus Fungsi Arang Aktif Tandan Aren (Arenga Pinnata Merr.) dengan Agen Aktivasi Potassium Silicate (K2SiO3)
This study aims to determine the effect of variations of the sugar palm activation temperature on the functional groups of activated charcoal from palm bunch (Arengga Pinnata Merr) with potassium silicate (K2SiO3) activation agent. The process of making an chemically activated charcoal is divided into three stages, firstly the preparation stage of preparing the palm bunches into cutting, washing and drying, secondly carbonitation stage at a temperature of 300oC – 400oC about ± 8 hours and the chemical activation stage. Potassium silicate K2SiO3 is a new activation agent that is used to activate an activated charcoal by using 2 : 1 ratio (K2SiO3: activated palm bunches) for 12 hours and an activation temperature of 600oC, 650oC, 700oC, 750oC, and 800oC for 30 minutes. Characterization of activated charcoal from palm bunches was tested by using Fourier Transform Infrared (FTIR). The FTIR spectrum shows that the activated charcoal produced has an absorption pattern with the types of bonds are C≡C (Alkuna), C=C (Aromatic Rings), C-H (Alkanes), Si-O and C-H (Alkanes). The Information was obtained that a good activation temperature for activated charcoal of palm  bunches was seen at temperatures of 650oC, 700oC and 750oC with the largest IR absorption was seen at temperatures of 700 oC.
