POTENSI ZAT WARNA DARI EKSTRAK ETANOL KULIT MANGGIS DAN KAYU SAPPANG SEBAGAI KALORIMETRI ANION
Abstract
Dyes from mangosteen skin and sappang tree have been isolated using ethanol as a solvent. Antocianinecompound is obtained from mangosteen skin while braziline is from sappang tree. Both of compounds can be used asanion clorimethric due to their hidrocyle and chromophoregroupactive sites. Dyes from mangosteen skin and sappangtree have been tested on 10 gram of several types of saturated anions (carbonate, sulfate, phosphate, cyanide, acetate,borax, nitrite, chloride, bromide, and iodide). The results of the tests show that thecolor of the dye from mangosteen skinchanges in cyanide and hydroxide anions. On the other hand, the color of the dye from sappang tree changes incarbonate, phosphate, cyanide, acetate, nitrite, and hydroxile. UV/Vis is used to detect the limit of cyanide anion.Methanol and acetone show positive results on both of dyes in cyanide anion. Detection limit of antocyanine andbraziline are 4x10-4 Mand 3x10-4 M respectively. With addition of cyanide anion, antocyanine in acetone has abatochromic shift at 2x10-4M and dye from sappang tree has detection limit at 1x10-4 M.References
