摘要

椰子是印尼经济的重要组成部分。椰子的经济价值很高的部分是椰子壳。这项研究的目的是研究用盐酸、醋酸和硝酸盐精炼产生的红外光谱模式。椰子壳温度的dipirolisis±300oC净化接下来两个小时做三种溶剂HCl)、CH3COOH和HNO3。每个提炼木炭的角色都使用傅里叶红外转录(FTIR)进行分析。FTIR谱显示了吸收带的峰值，使用盐酸(HCl)的强度显著增加。碳木炭结构的特征是C=O和C=C的群组出现。抽象的椰子是印尼经济中上演的重要角色的工业植物之一。高经济价值的椰子的一部分是椰子壳。这项研究采用了氢氯酸、乙酸和硝酸的净化方式来研究丙烯酸。椰子壳是pyrolyzed at a±的温度为2小时然后purified 300oC和三个types of solvents namely HCl)、CH3COOH和HNO3。每一项指控的特点都是用傅立叶红外线Transform (FTIR)对其进行分析。FTIR spectrum使用氢氯酸(HCl)，用一种意味深长的水氯酸(水氯酸)来表演白带带急剧上升的岩层。碳特征由C=O =C的功能确定。

POLA INFRAMERAH ARANG TEMPURUNG KELAPA HASIL PEMURNIAN MENGGUNAKAN ASAM

Kelapa merupakan salah satu tanaman industri yang memegang peranan penting dalam perekonomian Indonesia. Bagian kelapa yang memiliki nilai ekonomis yang tinggi adalah tempurung kelapa. Penelitian ini bertujuan untuk mengkaji pola spektrum inframerah arang hasil pemurnian menggunakan asam klorida, asam asetat, dan asam nitrat. Tempurung kelapa dipirolisis pada suhu ± 300oC selama 2 jam selanjutnya dilakukan pemurnian dengan tiga jenis pelarut yaitu HCl, CH3COOH, dan HNO3. Karakter masing-masing arang hasil pemurnian tersebut dianalisis menggunakan Fourier Transform Infrared (FTIR). Spektrum FTIR menunjukkan puncak pita serapan dengan peningkatan intensitas yang signifikan menggunakan asam klorida (HCl). Karakteristik struktur arang karbon teridentifikasi dengan munculnya gugus fungsi C=O dan C=C.ABSTRACT Coconut is one of the industrial plants that plays an important role in the Indonesian economy. The part of coconut that has a high economic value is the coconut shell. This study was aimed to examine the infrared spectrum pattern of charcoal purified using hydrochloric acid, acetic acid, and nitric acid. Coconut shell was pyrolyzed at a temperature of ± 300oC for 2 hours and then purified with three types of solvents, namely HCl, CH3COOH, and HNO3. The character of each refined charcoal was analyzed using Fourier Transform Infrared (FTIR). The FTIR spectrum showed the absorption band peaks with a significant increase in intensity using hydrochloric acid (HCl). The structural characteristics of carbon charcoal were identified by the appearance of C=O and C=C functional groups.
