Adsorption of Lanthanide Ions from Aqueous Solution in Multicomponent Systems using Activated Carbon from Banana Peels (Musa paradisiaca L.)

Abstract

Lanthanides in aqueous waste streams have received great attention due to their ability to pollute the environment. Therefore, efforts have been devoted to adsorbing lanthanides from waste industries. The evaluation of agro-waste by determining the adsorption efficiency of Ln 3+ ions is an important step in developing a process for Ln 3+ removal from water systems, as well as a method of isolating Ln 3+ ions from mineral ores, such as low-grade bauxite. The adsorption performance of banana peels (Musa paradisiaca L.) was evaluated in the removal of Ln 3+ ions. In addition, the adsorption of lanthanide ions from an aqueous solution in a multicomponent system was studied using activated carbon from banana peels. The selection of the best adsorbent was done by the iodine number method, where activated carbon had the highest iodine absorbance at 572.2 mg/g. The use of activated carbon as an adsorbent for the removal of commercial lanthanide ions from an aqueous solution was evaluated. The optimum condition in the Ln 3+ multicomponent system for the adsorption of Y 3+ , La 3+ , Ce 3+ , Nd 3+ , and Sm 3+ ions was determined to be a contact time of 2.5 h, a pH of 4, and an adsorbent dosage of 100 mg. The present research further supports the possibility of the adsorption of Ln 3+ ions from low-grade bauxite with adsorption efficiencies of 67.6, 71.0, 65.0, 62.9, and 56.6% for Y 3+ , La 3+ , Ce 3+ , Nd 3+ , and Sm 3+ , respectively.

Innovative Chemically Modified Biosorbent for Removal of Procion Red

“…The FTIR spectrum was showed the specific peaks in the fingerprint region 613 cm -1 which belongs to the halogen group of Cl. This result was similar to the previous study that the presence of carboxyl and hydroxyl groups affords the adsorption of organic pollutants (Kusrini et al, 2018).…”

Recoiled and Sputtered Radioactive Impurities in 11 MeV Proton-based F-18 Production

“…The existence of impurities is always an issue in radionuclide production. Future studies on adsorption of such impurities could be conducted using banana peel and coconut shell, as previously investigated for the adsorption of Ni ions (Olufemi et al, 2018), as well as analysis of solutions in multicomponent systems using activated carbon from banana peels for the adsorption of lanthanide ions (Kusrini et al, 2018), so that the impurity issue in F-18 radionuclide production can be solved.…”
