“…Previous investigations reported that surfactant-modified biomass enhanced adsorption capacity, for example in cetyl trimethyl ammonium bromide-modified coconut coir for Cr(VI) adsorption and other lignocellulosic materials. [20][21][22] Refer to these backgrounds and potency of peanut shell, this work is focusing on the utilization of peanut shell and the enhancement for the adsorption of dye over surfactant modification. Specifically, rhodamine B was used as dye model with respect to its vast utilization in Batik's industries.…”

Batch and flow adsorption experiments of rhodamine B were carried out by using peanut shell (PS) and sodium dodecyl sulfate-modified peanut shell (SDS/PS) as adsorbents. The study was aimed to evaluate the effect of SDS modification on the physicochemical character of PS and the kinetics of adsorption and adsorption capacity of PS. Instrumental characterizations consist of scanning electron microscope (SEM), Fourier Transform-Infra Red (FTIR), Boehm titration and gas sorption analyses were performed for evaluation. The results showed that SDS modification enhances the specific surface area and pore distribution. Kinetics of adsorption, adsorption isotherm, the effect of temperature, and adsorption thermodynamics were studied. It was found that in general, SDS modification enhance the adsorption rate of RhB, as well as affecting the adsorption kinetics. RhB adsorption over PS is fit to a pseudosecond-order model, while the adsorption over SDS/PS obeys Elovich kinetics model. Thermodynamic study of the adsorption kinetics was also conducted. Equilibrium study analyzed using the Langmuir, Freundlich, Temkin and Dubinin-Radushkevich (D-R) isotherms suggest that the adsorption data tend to obey D-R isotherm. The determined adsorption capacities of PS and SDS/PS are 133.146 and 236.699 meq/g.

“…Physical, chemical, and physicochemical processes are applied in removing heavy metals from wastewater [6]. Different B. Gezer methods such as chemical precipitation, solvent extraction, vacuum evaporation, membrane technologies, adsorption, ion exchange are used in waters containing heavy metal pollution [7], [8]. Among these methods, adsorption is the oldest and most well-known, more useful and economical method, as well as a well-established method.…”

In this study, activated carbon has been obtained by using sea urchin as an adsorbent substance, which is abundant, cheap, and natural in nature, as an alternative to active carbon used in heavy metal removal. Using the Ultrasound-assisted support, 1:1, 2:1, 3:1 (H3PO4/sea urchin) carbonization process was carried out by subjecting H3PO4 as the sea urchin activating agent. The BET surface area of the activated carbon obtained was characterized by total pore volume, ash content, and SEM analysis. Cu (II) removal in aqueous solutions were investigated with activated carbons. Experimental studies have been conducted to determine the effects of pH, contact time (min), adsorbent concentration (g/L), temperature, and initial metal concentration parameters affecting adsorption. The adsorption capacity of the activated carbon obtained from the sea urchin at 25 °C was calculated as 643 mg/g. Optimum conditions from the results were determined as pH 2.0, contact time 80 minutes, initial adsorbent concentration 10 mg/L, and temperature 25 °C. According to the results of the study, it has been concluded that the activated carbon obtained from the sea urchin can be an alternative adsorbent to other activated carbons in heavy metal removal.

“…Atık sulardan boyar maddelerin uzaklaştırılmasında fiziksel, kimyasal ve fizikokimyasal işlemler uygulanmaktadır [9]. Atık sulardan renk giderimi için oksidasyon, iyon değiştirme [10], ozonlama, koagülasyon, flokülasyon [11], çöktürme ve adsorpsiyon yöntemleri kullanılmaktadır [12]. Bunların arasında adsorpsiyon basit, ekonomik ve verimli bir yöntem olması sebebi ile çok fazla tercih edilmektedir [13].…”

Bu çalışmada nar ekşisi yapımında atık olarak ayrılan nar kabuklarından kimyasal aktivasyon yöntemi ile aktif karbon üretimi yapılmış ve metilen mavisi adsorpsiyonu test edilmiştir. Ön analizleri yapılan nar kabukları kütlece 0.5:1, 1:1, 2:1, 3:1 KOH/nar kabuğu oranlarında KOH ile karıştırılıp (500-600 o C) farklı sıcaklıklarda karbonize edilmiştir. Yapılan BET analizlerinde, 3:1 KOH/nar kabuğu oranında ve 600 o C karbonizasyon sıcaklığında hazırlanmış aktif karbonun en yüksek yüzey alanına (900,12 m 2/ g) sahip olduğu görülmüştür. Adsorpsiyon çalışmaları kapsamında farklı başlangıç konsantrasyonun, sıcaklığın ve pH'ın metilen mavisi adsorpsiyonuna etkisi araştırılmıştır. Farklı pH'larda yapılan çalışmalar göstermiştir ki bazik ortamlarda MM(Metilen Mavisi) adsorpsiyonu artmıştır ve pH 12 (adsorpsiyon verimi % 95) ortamında en iyi MM giderimi sağlanmıştır. Sıcaklığın etkisinin incelendiği çalışmalar sıcaklığın 25 ⁰C'den 35 ⁰C'ye ve 45 ⁰C'ye yükseltilmesi MM adsorplanma hızını arttırdığını göstermiştir. Başlangıç konsantrasyonundaki artış aynı miktar adsorban tarafından adsorplanan MM miktarını attırmıştır. Deneysel verilerin Langmuir ve Freundlich izotermlerine uygunluğu araştırılmış ve Langmuir izotermi ile uyumlu olduğu görülmüştür.
