“…The hybridization process with Spirulina sp. algae biomass is reflected by the emergence of C-H absorption band characteristics from aliphatic (−CH 2 ) at 2931.8 cm − 1 [17]. This is confirmed by the loss of Si-O stretching vibration from Si-OH observed at 964.4 cm − 1 caused by the reduction of the silanol group due to condensation that occurs with the biomass of Spirulina sp.…”

“…The processing of CV and MB dyes waste has been carried out through several processes such as oxidation [11], coagulation and flocculation [12], adsorption [13,14] and ion exchange [15]. The adsorption process is one of the right ways to treat waste containing dyes and heavy metals before being discharged into the environment, because the adsorption method is simple, relatively inexpensive, and does not cause side products that are harmful to the environment [16,17]. The success of the adsorption process is largely determined by the suitability of the properties and types of adsorbents used.…”

In this study, the adsorbent of Crystal Violet (CV) and Methylene Blue (MB) dyes was synthesized from the hybridization of Spirulina sp. algae biomass with silica as a matrix (ASS). Hybridization of Spirulina sp. algae biomass was carried out through a sol-gel process using tetraethyl orthosilicate precursors. The ASS adsorbent was characterized using Fourier-transform infrared spectroscopy, X-ray diffraction, Brunauer-Emmett-Teller surface area method and scanning electron microscopy-energy-dispersive-X ray. The CV and MB dyes adsorption onto ASS adsorbent was studied through adsorption experiments using the batch method. The optimum adsorption of CV and MB dyes is at pH of 8 and contact time of 60 min. The CV and MB dye kinetics on the ASS adsorbent tend to follow the pseudo-second-order kinetics model with rate constant (k2) of 0.3 and 0.2 (g mg− 1 min− 1) respectively. The isotherm adsorption pattern of CV and MB dyes follows the Freundlich adsorption isotherm with KF values of 1.07 and 1.05 (mg g− 1) (L mg− 1)1/n, respectively. In the simultaneous adsorption process, CV dyes were more adsorbed than MB in solution to the ASS adsorbent.

“…Metode adsorpsi merupakan metode yang paling banyak digunakan karena memiliki efisiensi yang tinggi. Selain itu, adsorpsi juga memiliki keunggulan lainnya seperti biaya yang relatif murah, metode yang lebih sederhana, bersifat ramah lingkungan serta tidak adanya efek samping yang beracun (Buhani et al, 2017).…”

Pada penelitian ini telah dilakukan pembuatan dan karakterisasi adsorpsi karbon aktif dari cangkang buah karet. Tahap pembuatan melalui aktivasi fisika yang dilanjutkan pada aktivasi kimia dan proses karakterisasi. Aktivasi fisika dilakukan dengan suhu tinggi, aktivasi fisika-kimia dilakukan pengeringan dalam oven pada suhu tinggi. Karbon aktif hasil sintesis dilakukan analisis proksimat dan dikarakterisasi menggunakan Scanning Electron Microscope (SEM) untuk mengetahui morfologi permukaannya. Fourier Transform Infrared Spectroscopy (FTIR) untuk mengetahui gugus fungsi pada permukaan karbon aktif. Hasil akhir adsorbat dikarakterisasi dan dianalisis menggunakan Spektrofotometer UV-Vis untuk mengetahui perubahan gugus fungsi. Uji adsorpsi pada karbon aktif terhadap metil jingga dan fenol dilakukan dengan pengujian ph dan waktu kontak optimum untuk mengetahui model kinetika dan konsentrasi adsorbat optimum untuk mengetahui pola isoterm adsorpsi. Hasil analisis proksimat menunjukkan nilai kadar air dan kadar zat menguap pada CAP lebih sedikit daripada CAPC. Sedangkan nilai kadar abu dan kadar karbon terikat pada CAP lebih banyak daripada CAPC.

“…Among these methods, adsorption stands out for its simplicity, effectiveness, efficiency, and the potential for adsorbent regeneration [10]. It is an environmentally friendly approach, especially suitable for dyecontaining waste due to its cost-effectiveness and non-production of harmful by-products [11,12]. Adsorption efficacy largely depends on the nature and type of adsorbent used.…”

<p>This study developed nanofibers derived from sugar palm fiber waste, incorporating citric acid and polyethylene glycol (PEG) modifications to adsorb crystal violet (CV) dye. The synthesis process involved alkalization-acid hydrolysis and bleaching techniques. Subsequent analyses of nanofiber characteristics were conducted using Fourier-Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), and Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDX). The efficacy of these modified nanofibers in adsorbing CV was quantitatively measured using an Ultraviolet-Visible (UV-Vis) spectrophotometer. The study successfully synthesized nanofibers from sugar palm fiber waste with modifications: PEG-modified nanofibers (NP 2 and NP 24) and citric acid-modified nanofibers (NS 2 and NS 24). These modifications resulted in nanofibers with a smooth, white texture. FTIR analysis of the samples (N, NP 2, NP 24, NS 2, and NS 24) revealed the presence of functional groups essential for cellulose, specifically -OH, C-H, and C-O groups. The addition of citric acid introduced a new group, C=O, albeit with very weak intensity. PEG modifications were evident from the stretching observed in the -OH groups. SEM analysis confirmed the presence of a layer on the nanofibers, attributed to citric acid (NS 2 and NS 24) and PEG (NP 2 and NP 24). XRD results indicated that the pre-and post-modification nanofibers exhibited a semi-crystalline phase. The adsorption mechanism was predominantly guided by Van der Waals electrostatic interactions between the absorbent material and the adsorbate. Intriguingly, the citric acid and PEG modifications did not significantly alter the adsorption outcomes. The adsorption capacity remained stable over time, as evidenced by measurements of 0, 15, 30, 45, 60, 90, and 120 minutes.</p>
