“…in 2015, in the previous study, the functional group that was identified was in the form of OH streching which could be read at wavenumbers 3304.6 and 3289.63 cm-1 which came from hydroxyl groups in alcohols and carboxylic acids at wavenumbers ranging from 3600 to 3200 cm-1 in the FTIR spectrum. Then the identification of the C-H Stretching functional group at the wavenumber 2924.74 cm-1 and group of C=O streching from the ester compound group at the wavenumber 1635.02 cm-1 [15] [16]. Litchi peel Adsorbent is used to overcome the contamination of metal ions Cu(II) and Pb (II) in liquid waste.…”

Dyes are a mixture of organic compounds that are synthesized in complex forms and are often used in the process of coloring products in various types of industries, so that this complex structure will be difficult to decompose naturally. Therefore, this dye will accumulate in the liquid waste. The accumulation of these dyes will cause harm to living things and the surrounding environment. Therefore, an effective method is needed to overcome this problem, a method that can be used to reduce the dye content in a simple and environmentally friendly way such as the adsorption method. In this study, the adsorption method using a column was used to absorb dyes from the cationic group, namely methylene blue and rhodamine B with adsorben derived from longan peel waste. In this study, the results obtained were the identification of longan peel containing several functional groups, namely O-H, C-H, C=O, -C-NO2, C=C, C-O-C, and C-N derived from alcohol, carboxylic acid, ester, ether, aromatic nitro compounds, and amines. By using a adsorbent particle size of 106 µm, it can absorb methylene blue and rhodamine B at 30.31 mg/g and 28.28 mg/g, respectively. The absorption of methylene blue with 0.1 gram of adsorbent resulted in an absorption capacity of 59.97 mg/g while 0.2 gram of adsorbent could absorb rhodamine B of 32.40 mg/g.

“…This is because the amount of adsorbed Mn has exceeded the maximum number of Mn that adsorbents have reached saturation. If a lot of adsorbents have saturated the active site on the surface of the adsorbent, further adsorption time will no longer increase the adsorption and even tends to reduce it (Kurniawati et al 2021).…”

The current study determined the potential of chemical modified banana blossom peels (BBP) as an adsorbent for the removal of manganese (Mn) from water. The BBP adsorbent was characterized using Field Emission Scanning Electron Microscopy (FESEM), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD) and Brunauer-Emmet Teller (BET). The effects of the solution pH, adsorbent dosage, initial manganese concentration and contact time towards the adsorption process were evaluated in batch adsorption studies. FESEM analysis displayed a deeper dents and rough internal surface that cater for deposition of Mn, while EDX analysis detected the presence of C, O, and Na elements (before adsorption); C, O and Mn (after adsorption). FTIR analysis revealed presence hydroxyl, carboxylic and amino groups which are responsible for the adsorption process. Moreover, XRD analysis showed that the structure of the BBP adsorbent is amorphous. The BET surface area of BBP adsorbent was 2.12 m2/g with the total pore volume of 0.0139 cm3/g and average pore diameter of 64.35 nm. The BBP adsorbent showed promising results of 98% Mn removal at optimum condition of pH 7, 0.5 g (adsorbent dosage), 10 mg/L of Mn initial concentration in 150 min contact time. Adsorption isotherm data were fitted with linear Langmuir and linear Freundlich model best fit with R2 > 0.98, while the adsorption process take place as a function of chemisorption process as determined using linear pseudo-second order kinetics. The maximum desorption rate of Mn was achieved at 92% in the first cycle with recovery rate of 94.18% Mn removal within 30 min using 0.1 M HCl. These findings confirmed the potential BBP as a natural adsorbent for Mn removal as an effective treatment option for enhancing wastewater quality.

“…In terpenoid compounds, it contains lanceolate acid and lansiolic acid. 7 Activated carbon used as adsorption is very effective in reducing heavy metal contaminants in the environment. Several studies have used activated carbon as an adsorbent, namely activated carbon from the bark of salak on the adsorption of Cu 2+ metal ions using KOH activator with the best adsorption at a dosage variation of 90 mg with a pH of 5.…”

Copper is one of the dangerous heavy metals contained in industrial wastewater, whose presence needs to be addressed. Adsorption is one method that can be used to adsorb heavy metals. Using a langsat shell as an adsorbent is used to adsorb copper because it is easy to obtain and its use is still minimal in people. Using the column method, the langsat shell was made into activated carbon with HNO3 as an adsorber of Cu2+ metal ions. The activated carbon obtained was tested for quality according to Standard Nasional Indonesia (SNI) No.06-3730-1995. In this research, we determine the effect of adsorbent dosage on the adsorption of copper ions. The results showed the activated carbon meets established quality standards of SNI and the optimum adsorption value of Cu2+ metal ions at an adsorbent dosage of 0.4 grams.
