“…Considering its high R 2 value and also low SE value, Elovich model provided the best fit to the experimental data of dye biosorption. This model suggests that the biosorption of dye occurs on the heterogeneous surface active sites of biosorbent [3,12]. The intra-particle mass transfer model showed that the biosorption process might be governed by multi-step mechanisms [4,13].…”

“…According to the statistical evaluation results, Langmuir model showed the best fit to the equilibrium data of dye biosorption. This isotherm model suggests that the biosorption of pollutant takes place on the homogeneous surface of biosorbent and the treatment of pollutant follows a monolayer biosorption process [12,17]. The values of nF lying in the range of 1 and 10 and the values of RL lying in the range of 0 and 1 indicate that this dye biosorption system is a favorable treatment process [1,3].…”

In the present study, the usage potential of sawdust as a forest industry waste was evaluated for the treatment of colored industrial effluents containing Fast Green FCF synthetic dye. The effects of various environmental variables such as pH, biosorbent amount, synthetic dye concentration and contact time on the dye removal ability of biosorbent material were studied in batch operating conditions. The kinetic and equilibrium studies were performed to elucidate the dye biosorption behavior of biosorbent. The synthetic dye biosorption capacity of biosorbent was highly affected by the environmental conditions. The kinetic and equilibrium studies showed that Elovich and Langmuir models were the best models for the elucidation of dye removal behavior of biosorbent. Based on Langmuir model, the maximum monolayer biosorption capacity under the optimum environmental conditions was estimated to be 26.834 mg g -1 . The obtained results revealed that the forest industry waste biomass used has usage potential for the treatment of synthetic dye pollution in aquatic environments.

“…In the preliminary step of optimisation, the selected initial concentration (mg/L), dosage (g/L) and pH was taken. The biosorption process was considered under equilibrium condition with a contact time of 60 min at ambient temperature 27±3ºC [45] 3.…”

“…In a recent study, it was reported that ANN modelling was used to predict the removal of non-toxic dye by Graphene oxide (GO) nanoplatelets and an R of 0.96452 was reported with network topology of 3-10-1 [44]. ES as dye biosorbent has never been reported in term of pretreatment effect, optimization and reusability but batch biosorption using OFAT method has been documented previously [45]. Therefore, the main motivation behind the study is to expands the body of knowledge of ES on the capability of the aforesaid biosorbent to (1) undergo pretreatment; (2) the determination of the optimal experimental condition for maximum removal efficiency using contemporary multivariate models namely Response Surface Methodology (RSM) and Artificial Neural Networks (ANN), and;…”

Red algae species, Euchema Spinosum (ES) in Malaysia possesses excellent biosorbent properties in removing dyes from aqueous solutions. In the present study, the experimental design for the biosorption process was carried out via response surface methodology (RSM-CCD). A total of 20 runs were carried out to generate a quadratic model and further analysed for optimisation. Prior to the evaluation, the characterisation study of the ES was performed. It was observed that the maximum uptake capacity of 399 mg/g (>95%) is obtained at equilibrium time of 60 min, pH solution of 6.9-7.1, dosage of 0.72 g/L and initial dye concentration of 300 g/L through statistical optimisation (CCD-RSM) based on the desirability function. It is demonstrated in the present study that the ANN model (R2=0.9994, adj-R2=0.9916, MSE=0.19, RMSE=0.4391, MAPE=0.087 and AARE=0.001) is able to provide a slightly better prediction in comparison to the RSM model (R2= 0.9992, adj-R2= 0.9841, MSE=1.95, RMSE=1.395, MAPE=0.08 and AARE=0.001). Moreover, the SEM-EDX analysis indicates the development of a considerable number of pore size ranging between 132 to 175 mm. From the experimental observations, it is evident that the ES can achieve high removal rate (>95%), indeed become a promising eco-friendly biosorptive material for MB dye removal.

“…İstatistiksel değerlendirme sonuçlarına göre, Freundlich modeli, boya biyosorpsiyonu denge verilerine en iyi uygunluğu göstermiştir. Freundlich izoterm modeli, kirletici biyosorpsiyonunun, biyosorbentin heterojen yüzeyinde gerçekleştiğini ve kirletici arıtımının, çok basamaklı bir biyosorpsiyon işleminden kaynaklandığını ifade etmektedir[20]. Ayrıca, yüksek KF değeri, biyosorbent materyalinin, su ortamından boya giderimi için büyük bir potansiyele sahip olduğunu ortaya koymuştur.…”

Bu çalışmada, Zostera marina L. atık biyoması ile sucul ortamdan model bir sentetik azo boyanın (basic red 46) biyosorpsiyonu ilk kez araştırılmıştır. Deneysel veriler, boya gideriminin önemli bir şekilde pH, biyosorbent miktarı, boya konsantrasyonu ve temas süresine bağlı olduğunu göstermiştir. Optimal biyosorpsiyon koşulları, pH 8, 10 mg biyosorbent dozajı, 30 mg L-1 boya konsantrasyonu ve 360 dakika temas süresi olarak belirlenmiştir. Biyosorpsiyon kinetik verileri, yalancı birinci mertebe, yalancı ikinci mertebe, Elovich ve parçacık içi difüzyon modelleri kullanılarak analiz edilmiştir. Freundlich, Langmuir ve Dubinin-Radushkevich modelleri, deneysel izoterm verilerini modellemek için kullanılmıştır. Modelleme çalışmaları sonuçları, Elovich ve Freundlich modellerinin, biyosorpsiyon kinetik ve izoterm verilerine en iyi uyumu sağladığını göstermiştir. Langmuir denge modeline bağlı olarak biyosorbentin maksimum boya biyosorpsiyon kapasitesi, 160,882 mg g-1 olarak tahmin edilmiştir. Termodinamik çalışmalar, biyosorpsiyon prosesinin doğasını ortaya koymak için yapılmıştır ve elde edilen sonuçlar, biyosorpsiyon sisteminin, spontan ve fiziksel bir doğaya sahip olduğuna işaret etmiştir (ΔG° =-8,604-5,926 kJ mol-1). Elde edilen tüm bulgular, bu doğal biyolojik atığın, su ortamından böyle kirletici ajanların uzaklaştırılması için uygun maliyetli bir biyosorbent materyali olarak etkili bir şekilde kullanılabileceğini göstermiştir.
