“…The absorptivity test procedure was carried out with 100 mL of 10 ppb arsenic solution pipetted into a 250 mL Erlenmeyer and then added carbon nanofiber with a mass of 0.1 grams, then shaken for 90 minutes. Then, it was filtered with Whatman filter paper, and the filtrate was taken to measure its absorbance by employing Atomic Absorption Spectroscopy (AAS) [12].…”

Heavy metal wastes cause water pollution. One of them is very toxic arsenic heavy metal waste; thus, treating them before they are released freely into the waters is necessary. In this case, the manufacture of carbon nanofibers (CNF) from sugar palm fiber waste is an innovation that can produce adsorbents to remediate heavy metals, thereby increasing the use value of sugar palm fiber waste. Carbon nanofiber from palm fiber (Arenga pinnata) was modified with ZnO metal, with varying concentrations of 0.1%, 1%, and 10%, in 1 gram of carbon nanofiber. Carbon nanofibers were made by carbonizing sugar palm fibers at 300oC for two hours. Furthermore, wet impregnation was carried out with Zn(CH3COO)2.2H2O and ended with calcination at 250oC for an hour, resulting in black nanofiber powder. This research was conducted to determine the effect of ZnO concentration on the characteristics of the carbon nanofiber produced and its effectiveness in remediating heavy metal arsenic. The ZnO/carbon nanofiber adsorbent material was then characterized using FTIR, XRD, and SEM analyses. Determination of the absorption of ZnO/carbon nanofibers on heavy metal arsenic was also assessed employing AAS analysis.

“…Berdasarkan faktor-faktor tersebut terdapat beberapa penelitian yang telah dilakukan dengan menggunakan berbagai metode seperti metode alkali hidrotermal serta metode ektraksi dengan variasi konsentrasi HCl yang menghasilkan konsentrasi optimum sebesar 5M [7] dan metode step change of temperature dengan variasi suhu kalsinasi yang optimum pada suhu 500 0 C [8] .Oleh karena itu, akan dilakukan sintetis zeolit A berbahan dasar limbah abu terbang (fly ash) limbah PT.ICA menggunakan metode alkali hidrotermal dengan variasi rasio SiO2 dan Al2O3. Penelitian ini bertujuan agar dapat menjelaskan karakteristik dari zeolit A yang disintesis dari limbah fly ash PLTU PT.ICA dengan variasi rasio SiO2 dan Al2O3.…”

Fly ash is one of the combustion residues from coal-fired power plants which is produced in large quantities. The main elemental composition of fly ash is silica and alumina with content of 48.055% and 14.653%, respectively. This study aims to determine the characteristics of zeolite A synthesized from fly ash with various ratios of SiO2 and Al2O3. Zeolite A was synthesized using the alkaline hydrothermal method by varying the Si/Al molar ratio of 0.8 1 and 1.2. The initial process begins with the leaching process of fly ash waste and is followed by alkaline smelting. Furthermore, zeolite A was synthesized by adding sodium silicate and sodium aluminate to form a white gel. These steps were followed by a hydrothermal process using a hydrothermal autoclave at a temperature of 100֯C for 5 hours. Qualitative results on XRD showed that zeolite A synthesized at a ratio of Si/Al 1,2 had a 2ϴ position closer to standard zeolite A, which was seen based on the highest peaks at 2ϴ=12,420, 16,070, 20,360, 21,590, 23,960, 26,070, 27,080, 29,910, 32,500, 41,480, 44,090, 52,540, 54,230 and 66,660 and the structure formed is in cubic form with a crystallinity of 76.36%. Analysis using XRF showed that the Si/Al 1.2 ratio was the best for the formation of zeolite A. In this variation the silica and alumina content increased by 54.412% and 35.054%, respectively
