“…Ligand absorption happens when the surface's -OH group is a ligand and forms a compound with a metal ion. The -OH group can donate electrons and establish coordination bonds with metal ions, resulting in complexes [13]. Lead, a Group IVA metal, is not quickly reactive.…”

Heavy metal contamination in the environment is now quite concerning, and it is hazardous if it enters the body. Continuous human interaction with heavy metal lead (Pb) will result in various health problems. Nipa palm is a palm (Palma) thrives in mangrove forest habitats or along the seashore, with a cellulose content of 35.1%, 26.4% hemicellulose, and 17.8% lignin. This research aims to see if palm fronds (Nypa fruticans) can be used as a biosorbent to remove the heavy metal Pb in artificial solutions. The analysis was carried out in phases, beginning with the creation of biosorbents from Nipah fronds by decreasing their size to powder and drying them in the sun, followed by analyzing the efficacy of the biosorbents and the number of functional groups using the FTIR instrument. The research was carried out by varying the particle size of the nipa palm frond adsorbent, namely 40, 60, and 80 mesh, as well as contact times of 30, 60, 90, and 100 minutes, to determine the level of adsorption absorption and the adsorption mechanism using the Langmuir and Freundlich isotherm equation approach. The Pb solution used had a concentration of 20 ppm. The results showed that the maximum metal absorption level was 99.29% at a particle size of 80 mesh with a contact time of 100 minutes. The absorption mechanism is close to the Langmuir isotherm equation with R2 = 0.9998. It is suspected that the adsorption process occurs in one layer (monolayer) of the adsorbent.

“…In Indonesia, mango is one of the most familiar horticultural commodities because it can be processed in various forms. In the mango processing industry, mango peel (which contributes to 7-24% of total weight) is dumped as waste (Ghosh et al 2019) This can cause environmental problems especially related to land use for disposal. Mango peel contains many polymer compounds that have functional groups such as pectin and cellulose (Correia et al 2018).…”

“…Mango peel contains many polymer compounds that have functional groups such as pectin and cellulose (Correia et al 2018). This polymer can increase the possibility of mango peel as a carbon source that can be converted into activated carbon (Ghosh et al 2019) which can be utilized further to adsorb heavy metal waste such as Fe 2+ which is large presence in batik industrial waste.…”

A B S T R A C TMango peel waste which has a carbon functional group was converted to activated carbon. The as-synthesized activated carbon (AC) was then utilized as an adsorbent for batik waste which contains heavy metal substances such as Fe2+. The purpose of this study was to determine the optimum process variation in absorbing heavy metal ion Fe contained in batik waste. Four variation methods of activated carbon synthesis were explored to determine the most suitable method of AC synthesis. The results showed that the sample synthesized using a combination physical-chemical-physical process was the best process variation resulting in percentage removal of Fe2+ of 84.81%. FTIR showed that the functional groups in mango peel were visible for all variations of the process, namely hydroxyl (-OH) derived from cellulose and hemicellulose and carboxyl (-COOH) derived from pectin. The adsorption study showed that the most suitable isotherm for all process variations was Langmuir with an R2 value of 0.9999 for the MPAC-4 sample. The adsorption mechanism is physisorption with a value of E < 8 kJ/mol based on the D-R isotherm and has the largest adsorption capacity of Qmax 8.2 mg/g.Keywords: batik waste; adsorption; activated carbon; iron waste; mango peelABSTRAKLimbah kulit mangga yang memiliki gugus fungsi karbon dapat dikonversi menjadi karbon aktif. Karbon aktif hasil sintesis (AC) tersebut selanjutnya dimanfaatkan sebagai adsorben limbah batik yang mengandung zat logam berat seperti Fe2+. Tujuan dari penelitian ini adalah untuk mengetahui variasi proses optimum dalam menyerap ion logam berat Fe yang terkandung dalam limbah batik. Terdapat 4 variasi metode sintesis karbon aktif yang diteliti untuk menentukan metode sintesis AC yang paling cocok. Hasil penelitian menunjukkan bahwa sampel yang disintesis menggunakan kombinasi proses fisika-kimia-fisika merupakan variasi proses terbaik dengan persentase penyisihan Fe2+ sebesar 84,81%. Analisis FTIR menunjukkan bahwa gugus fungsi pada kulit mangga terlihat untuk semua variasi proses, yaitu hidroksil (-OH) yang berasal dari selulosa dan hemiselulosa dan karboksil (-COOH) yang berasal dari pektin. Studi adsorpsi menunjukkan bahwa isoterm yang paling cocok untuk semua variasi proses adalah Langmuir dengan nilai R2 = 0,9999 untuk sampel MPAC-4. Mekanisme adsorpsi adalah fisisorpsi dengan nilai E < 8 kJ/mol berdasarkan isoterm DR dan memiliki kapasitas adsorpsi terbesar Qmax 8,2 mg/g.Kata kunci: limbah batik; adsorpsi; karbon aktif; limbah besi; kulit mangga
