“…[16]. Berdasarkan beberapa penelitian sebelumnya mengenai adsorben dari karbon aktif didapatkan hasil bahwa adsorben dari biomassa ini efektif dalam menyerap polutan, bau, minyak, serta senyawa organik beracun lainnya [17]. Meskipun demikian, karbon aktif dinilai kurang ekonomis sehingga dibutuhkan cara lain yang memiliki kema mpuan kerja yang sama namun terjangkau dalam hal keekonomisannya.…”

Adsorpsi bahan pencemar dengan menggunakan biomassa telah banyak diteliti dua diantaranya adalah menggunakan abu sekam padi dan rumput laut. Dalam penelitian ini bertujuan untuk mengkaji bagaimana kombinasi dua biomassa tersebut dalam menurunkan nilai cemaran limbah serta untuk mengetahui bobot adsorben dan waktu kontak optimum terhadap kemampuan bioadsorben dalam mengadsorpsi limbah cair. Efektifitas bioadsorben diuji melalui beberapa parameter yakni pH, turbiditas, kadar logam Cd, total padatan tersuspensi (TSS) dan COD. Dosis optimum yang paling efektif dalam menurunkan cemaran limbah cair industri minuman ringan adalah pada 0,5 gram dalam 150 mL limbah cair selama 30 menit dan 1.5 gram selama 30 menit pada penurunan kadar logam Cd yang diuji menggunakan adsorben abu sekam padi. Kemudian dilakukan variasi kombinasi rumput laut dan abu sekam padi 100, 75, 50, dan 25(%). Dari kombinasi tersebut rumput laut sebanyak 100% memiliki efektivitas yang paling tinggi dengan penurunan kadar pH sebesar 27 %, turbiditas sebesar 75,16 %, TSS sebesar 91,43 % dan COD sebesar 97,77 %.

“…Banana trees are widely cultivated and used for a variety of purposes. Bananas account for about 16% of overall fruit output, making them the second-largest fruit globally, with Malaysia accounting for 32% of total fruit production [29]. Research on the banana blossom as an adsorbent for contaminant removal is limited.…”

Chemical Treatment of Banana Blossom Peels Adsorbent as New Approach for Manganese Removal: Isotherm and Kinetic Studies

This research aimed to investigate the potential of chemically modified banana blossom peels (BBP) as an adsorbent for removing manganese (Mn) from water. Zeta potential, field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and Brunauer–Emmet–Teller (BET) were used to characterise the BBP adsorbent. Batch adsorption studies were used to assess the effects of the solution pH, adsorbent dosage, initial manganese concentration, and contact time of the adsorption process. Zeta potential of BBP with a value of −9.87 to −21.1 mV and FESEM analysis revealed deeper dents and rough internal surfaces conducive to Mn deposition, whereas EDX analysis revealed the presence of C, O, and Na elements (before adsorption); C, O, and Mn (after adsorption). The presence of hydroxyl, carboxylic, and amino groups, which are responsible for the adsorption process, was discovered using FTIR analysis. Furthermore, XRD analysis revealed that the BBP adsorbent structure is amorphous. The BBP adsorbent has a BET surface area of 2.12 m2/g, a total pore volume of 0.0139 cm3/g, and an average pore diameter of 64.35 nm. The BBP adsorbent demonstrated remarkable results of 98% Mn removal under the optimum pH 7, 0.5 g (adsorbent dosage), and 10 mg/L of Mn initial concentration in 150 min of contact time. The linear Langmuir and Freundlich isotherm models best fit the adsorption isotherm data with the R2 > 0.98. In contrast, the adsorption process occurs as a function of the chemisorption as determined by linear pseudo-second-order kinetics. Using 0.1 M HCI, the maximal desorption rate of Mn was 92% in the first cycle, with a recovery rate of 94.18% Mn removal in 30 min. These findings support the use of BBP as a natural adsorbent for Mn removal as a treatment option for improving wastewater quality.

“…Ion exchange requires strong acid to regenerate the resin [4]. Of the methods described above, adsorption, especially biosorption, is the most effective and economical method [5]. One of the latest adsorption methods in separating heavy metals is by utilizing thermosensitive gel based on zwitterionic betaine [6].…”

Industrial development has caused the metal concentration in the environment to increase. This is a serious issue considering that heavy metals are stable and cannot naturally decompose. Therefore, wastewater should be processed before being disposed to the environment. Several technologies have been developed for removing heavy metal content in industrial liquid wastes. The adsorption method using solid adsorbent is a simple and effective method for separating heavy metal ions from electroplating wastes since they are eco-friendly and efficient. However, they produce secondary wastes and require high operational costs. The blending of cationic gel NIPAM-co-Chitosan and anionic gel NIPAM-co-Acrylic Acid is a potential candidate as a new alternative adsorbent. By this method, the secondary wastes can be eliminated, adsorbed ions simultaneously, and adsorb-desorb ions reversibly. NIPAM-co-Chi and NIPAM-co-Acrylic Acid are synthesized from a polymerization reaction using N, N, N’, N’-tetramethylethylenediamine (TEMED) and sodium sulfite as accelerators, ammonium peroxodisulfate (APS) as an initiator, and N, N’-methylene bisacrylamide (MBAA) as a cross-linker. The gel was synthesized in a three-neck round flask for 6 hours. The product crush gel was then used for the adsorption and swelling degree test. The swelling degree test was performed by measuring the swelling gel volume before and after being soaked for 24 hours in target solutions. The gel obtained from the adsorption test was separated from the solution to be analyzed with Atomic Absorption Spectrophotometry (AAS). Based on the FTIR analysis of NIPAM-co-Chi and NIPAM-co-Acrylic Acid gels, there is no peak indicating the presence of vinyl C=C bonds. It can be concluded that the gel copolymer synthesis that was carried out was successful. The optimum results were obtained from the swelling degree analysis on electroplating waste at a concentration of 8:2.
