“…[15] Activation process and modification by SDBS affect the functional groups on the surface of the sea sand as observed in Figure 1. Activation of sea sand caused the absorption intensity of the -OH silanol on the 3750 cm -1 increases, due to the substitution of metal cation with H + from acid solution [17]. Variations of SDBS concentration affect the generated IR spectrum.…”

This study aims to determine the effect of sea sand modification with SDBS for adsorption of Fe3+. Sea sand was treated with 0.1 M HCl solution at 25oC. Organo-quartz was prepared at SDBS concentration of below, equal, and above the CMC value by shaking the mixture for 4 hours at 100 rpm. Characterization by FTIR spectrophotometry showed a change in the spectra pattern. The activation caused increasing of -OH silanol while modifications make them decrease. Characterization with SEM showed that the morphology of the sea sand was not uniform with irregular white chunks. The EDX results showed that the dominant elements were C (13.89% ± 10.86), O (40.48% ± 6.58), Si (16.51% ± 8.13), and Fe (11.68% ± 14.38). Adsorption was carried out using Fe3+ at 50 ppm. The Fe3+ analysis was conducted by AAS. The adsorption value by activated sea sand was 58.22% ± 7.23% whereas without treatment sea sand was 70.46% ± 5.54, and the modified sea sand was 53.24% ± 4.86. The lower adsorption is probably caused by the dissolved iron oxides in sea sand during activation.

“…In general, the NaOH activator responsible oxidizes and destroys the carbon material surface, thereby leading to an increase in the SSA; it is also responsible for the formation of pores with a larger diameter (2.39 nm) (Setyaningsih et al, 2008 ). Similarly, the greater SSA and porosity of the KOH-treated adsorbents are also attributable to the occurrence of the gasification reactions shown in Equations (7–12):…”

Herein, we investigated polyacrylonitrile (PAN)-based porous activated carbon sorbents as an efficient candidate for CO 2 capture. In this research, an easy and an economical method of chemical activation and carbonization was used to generate activated PAN precursor (PAN-C) adsorbents. The influence of various activators including NaOH, KOH, K 2 CO 3 , and KNO 3 on the textural features of PAN-C and their CO 2 adsorption performance under different temperatures was examined. Among the investigated adsorbents, PANC-NaOH and PANC-KOH exhibited high specific surface areas (2,012 and 3,072 m 2 g −1), with high microporosity (0.82 and 1.15 cm 3 g −1) and large amounts of carbon and nitrogen moieties. The PAN-C activated with NaOH and KOH showed maximum CO 2 uptakes of 257 and 246 mg g −1 at 273 K and 163 and 155 mg g −1 at 298 K, 1 bar, respectively, which was much higher as compared to the inactivated PAN-C precursor (8.9 mg g −1 at 273 K and 1 bar). The heat of adsorption (Q st) was in the range 10.81-39.26 kJ mol −1 , indicating the physisorption nature of the CO 2 adsorption process. The PAN-C-based activated adsorbents demonstrated good regeneration ability over repeated adsorption cycles. The current study offers a facile two-step fabrication method to generate efficient activated porous carbon materials from inexpensive and readily available PAN for use as CO 2 adsorbents in environmental applications.

“…Pencucian karbon setelah aktivasi dilakukan untuk menghilangkan sisa residu organik, kontaminan, mineral dan sisa-sisa logam yang tertinggal dalam rongga pori. Oksida logam yang tertinggal didalam pori dapat mempengaruhi daya jerap karbon aktif pada senyawa tertentu (Setianingsih et al 2008). Kemampuan adsorpsi juga akan meningkat bila pH diturunkan yaitu dengan menambah asam-asam mineral, karena kemampuan asam mineral akan mengurangi ionisasi asam organik tersebut (Sembiring et al 2003).…”

Penggunaan bahan bakar yang terus meningkat mengakibatkan cadangan minyak bumi mengalami penurunan. Bahan bakar minyak (BBM) yang berasal dari fosil tidak dapat diperbaharui. Biofuel adalah salah satu sumber energi alternatif. Pembuatan Biofuel dapat dilakukan dengan perengkahan termal dan perengkahan katalitik minyak goreng bekas. Minyak goreng bekas dapat menjadi biofuel dengan proses perengkahan katalitik menggunakan katalis Co-Arang. Penelitian ini meliputi preparasi katalis kobalt-arang aktif dengan metode ion exchange, Karakterisasi katalis, dan perengkahan katalitik minyak jelantah. Konsentrasi larutan logam yaitu 1%, 2%, dan 3%, dengan variasi temperatur perengkahan yaitu 450°C, 500°C, 550°C. Karakterisasi dengan XRD menunjukkan struktur atom karbon berbentuk struktur amorf. Hasil karakterisasi dengan SEM-EDX didapatkan hasil logam kobalt yang teremban yaitu sebesar 0,86%, 1,99% dan 0,11%. Konversi rata-rata (%) CHP perengkahan minyak jelantah pada Konsentrasi katalis 1%, 2% dan 3% adalah 31,83%, 8,51% dan 11,43%.
