Peningkatan Kualitas Minyak Nilam Melalui Proses Adsorpsi Menggunakan Adsorben Î“-Alumina Dengan Sistem Flow
Use of research studies have been carried Î³ - alumina as an adsorbent in improvingÂ the quality of patchouli oil carried through the adsorption process flow system. QualityÂ improvement based on analysis of patchouli oil quality parameters in accordance with SNIÂ 06-2385-2006 about patchouli oil. These parameters include color, specific gravity, refractiveÂ index, acid value, the metal content of iron (Fe) and patchouli alcohol levels. FeÂ concentration measurements carried out using AAS instrument, and patchouli alcohol contentÂ measurement using GC instrument. Variations in the use of Î³ - alumina adsorbents includeÂ weight variation is 5, 10, 15, 20 grams and variation of flow rate is 5 and 10 drops/min.Â Percent increase of patchouli alcohol occurred in the use of alumina as an adsorbent as muchÂ as 10 grams with a flow rate of 10 drops / min, increase of 27.6775 %. Moreover, it has theÂ smallest Fe metal content is 11.2201 mg / kg. Colour, specific gravity, refractive index, andÂ levels of metals Fe after adsorption have met the quality standard patchouli oil.
