Abstract

Several industrial activities such as fertilizer industry, mining, battery, electronics and machinery can cause heavy metal pollution and one of them is Cu(II) heavy metal. At high levels of metal concentrations of Cu(II) will be very dangerous for the environment and living things, so it is necessary to find a solution to overcome the problem of metal pollution of Cu(II) is. One method that can be used is the biosorption method. In this study, pectin extract from kedondong fruit peel was used as a biosorbent. This research was conducted to determine the optimum mass of biosorbent in the biosorption process. Then the pectin characterization was carried out the Fourier Transform Infra Red instrument, then the absorbed Cu(II) metal content was determined using the Atomic Absorption Spectroscopy instrument. From this study, the optimum mass of biosorbent was 0.1 gram with an absorption capacity of 2,940 mg/g.

Abstract

Heavy metals are known to seriously injure land plants and animals, including humans, as well as marine species when present in contaminated water. For the batch adsorption technique used in this study, Cu(II) ions were removed from an aqueous solution using an inexpensive  environmentally friendly adsorbent prepared from the extracted pectin of ambarella fruit peel. The functional groups of the extracted pectin were studied using Fourier Transform Infrared Spectroscopy (FT-IR). Operational conditions like pH, contact time, and initial adsorbate concentration were investigated. FTIR characterization showed that pectin was successfully extracted from ambarella fruit peel with the appearance of the peaks at 3331.36 cm-1, 2924.02 cm-1, 1727.38 cm-1, 1626.20 cm-1, 1329.31cm−1, 1232.43cm−1, 994.18 cm−1 and these peaks have similar characteristic with a commercial pectin. The maximum uptake of Cu(II) ions was obtained at a pH of 4, a contact time of 90 min, an initial metal concentration of 150 ppm. The extracted pectin has an adsorption capacity of 6.5860 mg/g for the removal of Cu(II) ions from aqueous solution under the optimum adsorption conditions. In addition, the data obtained from contacting the extracted pectin of ambarella fruit peel in Batang Arau River water showed an adsorption capacity of 0.0376 mg/g. Therefore, the pectin that was extracted from the peel of the ambarella fruit could be used to filter out Cu(II) ions from aqueous solutions.
