“…11 The use of carbon, made from various materials, as an adsorbent to bind heavy metals has been described. [12][13][14] Peanut shell activated carbon and amino-functionalized magnetic biochar obtained from wasted peanut hull have been found to adsorb chromium (Cr) more efficiently than commercial carbon. [15][16] The adsorption of a range of heavy metals, such as Pb 2+ , Cd 2+ , Hg 2+ and Ni 2+ , by lignin precipitated from black liquor, which was carbonized at a temperature of 600 °C, has been studied.…”

Carbon was produced from peels and stems of kepok banana and was characterized. Also, its Cd(II) adsorption ability was determined. The carbon material was prepared through two-stage carbonization. First, carbonization was carried out at 400 °C for 30 minutes, and then it was continued at 450 °C and 500 °C for 10 minutes. The results showed that the carbon content obtained after carbonization of banana peels at temperatures of 400 °C, 450 °C and 500 °C was 60.92%, 55.16% and 50.11%, respectively, while that achieved from banana stems was 65.37%, 56.97% and 45.80%, respectively. The moisture content of the carbon prepared from banana peels was 7.01%, 5.37% and 5.28%, respectively, for each temperature level, while that of the carbon material made from banana stems was 4.93%, 4.17% and 3.44%, respectively. The ash content of the banana peel carbon prepared at different temperature levels was 4.56%, 7.23% and 11.04%, respectively, and that of the banana stem carbon was 7.73%, 9.65% and 13.85%, respectively. The highest iodine number of banana peel carbon (450 °C) was 1006.74 mg/g, while that of banana stem carbon (450 °C) was 1019.43 mg/g. Surface analyses were conducted using scanning electron microscopy -energy dispersive spectroscopy (SEM-EDS). The Cd(II) adsorbed by the carbon materials was measured using atomic absorption spectrometry (AAS). The results showed that increasing the weight of the adsorbent leads to an increased amount of adsorbed Cd(II).

“…2 In recent years, activated carbon has been produced from abundant, renewable and low-cost materials, which possess high carbon and low inorganic content. [3][4][5] Sawdust is a biowaste of the wood industry, mainly composed of cellulose (40-50%), hemicelluloses (20-40%) and lignin (20-40%). The accumulation of this residue causes environmental and health related issues.…”

Activated carbon was synthesized from Acacia leucophloea wood sawdust by a two stage chemical activation process. The first stage involved direct hydrolysis of the raw material to produce hydrochar. The second stage was the chemical activation of the hydrochar using ZnCl 2. In the present study, chemical activation, focusing on the effects of the impregnation ratio, carbonization temperature and carbonization time, has been investigated and the optimum production conditions were found to be as follows: 6:1 impregnation ratio, 600 °C carbonization temperature and 1 h carbonization time. The precursor and the activated carbon produced under the optimum conditions were characterized by several analytical techniques, such as elemental and proximate analyses, FE-SEM, FT-IR, TGA and BET surface area analysis. The adsorption performance of the activated carbon prepared towards anionic dye Direct Blue 2B was evaluated. The Langmuir model showed a better fit to the isotherm data, while kinetic data were fitted by the pseudosecond order model.

“…Some research results on biochar derived from agricultural plant biomass, especially from fruit peels such as banana peels [4], cocoa [5], durian [6], salak fruit seeds [7], coconut husk [8], has been published in various reputable journals both nationally and internationally. Generally, the research carried out is applied as an adsorbent for metal ions such as Chromium, Cadmium, Lead, and others metals contained in the solution.…”

Biochar preparation from biomass and organic materials such as fruit peels, livestock manure, wood chips, and other agricultural residues has been studied. Those materials are prepared through a pyrolysis process, heating at a specific temperature, then utilized for adsorption waste pollution such as heavy metal ions. This study aimed to produce activated biochar from corn stalks (ABCS) as an adsorbent of BOD and COD in hospital wastewater. Activation of the biochar was carried out with an activator agent, namely ZnCl2. The moisture and ash content of activated biochar with a pyrolysis temperature of 400℃ and 500℃ meet SNI. SEM-EDS determined the pore and elements analysis. ABCS consist of 44.88 % and 60.56% of the carbon produced with different temperature of 400℃ and 500℃, respectively. One gram of ABCS reduced COD up to 71.4% in 4.5 hours and a maximum of 56.83% of BOD in 3 hours. While in an hour, a maximum of 2.5 g ABCS decreased COD 62.5% and 71.1% of BOD with the most of 1.5 g ABCS.
