| Abstract: | The adsorption Cu2+ metal ion of pectin from “tongka langit†banana’s crust (Musa Speices van balbisiana) has been done. Pectin was obtained from extraction “tongka langit†banana’s crust with HCl at temperature 90 oC during 4 hours. Pectin was produced 9.49 grams (10.41%). Identification functional group of pectin before and after adsorption use FT-IR spectrophotometer and defractometer XRD while Cu2+ metal adsorption result was analized with using AAS. Adsorption Cu2+ metal was followed adsorption isotherm Freundlich with KF value = 4.33 mg/g and n value = 0.86. |
