“…In fact, certain widely available plant materials remain unused resources, thus the use of them could indeed be an environmentally friendly approach too (Ashraf et al, 2011). Various plant-based adsorbent agents have been tested under different conditions, such as seaweed (Basha et al, 2008;Hashim and Chu, 2004), marine algal biomass (Sheng et al, 2004), seafood processing waste sludge (Lee and Davis, 2001), sugar beet pulp (Reddad et al, 2002b), banana peel (Ashraf et al, 2011;Castro et al, 2011;Hossain et al, 2012), papaya wood (Saeed et al, 2005), grape stalk wastes (Villaescusa et al, 2004), neem bark (King et al, 2007), neem biomass (Arshad et al, 2008), tea-waste (Malkoc and Nuhoglu, 2007;Kamsonlian et al, 2011a), sawdust (Garg et al, 2004;Memon et al, 2005), tamarind bark (Prasad and Abdulsalam, 2009), tamarind hull (Verma et al, 2006), potato peel waste (Ahalya et al, 2005), maize corn cob, jatropha oil cake, sugarcane bagasse (Garg et al, 2007), rice husk (Kumar and Bandyopadhyay, 2006), rice straw (Gao et al, 2008), wheat straw (Robinson et al, 2002), wheat shells (Bulut et al, 2007), wheat bran (Sulak et al, 2006), maize leaf (Babarinde et al, 2006), wood and bark (Mohan et al, 2007), teak leaf powder (King et al, 2006), rubber leaf powder (Hanafiah et al, 2006), pine bark (Al-Asheh et al, 2000), saltbush (Sawalha et al, 2005), and olive pomace (Pagnanelli et al, 2003), orange peel (Kamsonlian et al, 2011b), etc.…”

BACKGROUND:Certain crop-based waste materials have been recognized as cost-effective and highly efficient adsorbents for removal and recovery of different kind of heavy metals from aqueous solutions. The ability is strongly attributed to the carboxyl functional group of some pectin substances such as galacturonic acid often found in fruit peels. The present manuscript was aimed at assessing the potential applicability of banana peel for metal removal from contaminated waters. METHODS AND RESULTS:As revealed by laboratory investigations, banana peel contains pectin (10-21%), lignin (6-12%), cellulose (7.6-9.6%), and hemicelluloses (6.4-9.4%). The pectin extraction is reported to have glucose, galactose, arabinose, rhamnose, xylose, and galactouroninc acid. Several studies conducted under different conditions proved that banana peel is capable of adsorbing 5. 71, 2.55, 28.00, 6.88, 7.97, and 5.80 mg/g of Cd

Abstract-Industrialization is the backbone for the development of any country, but pollution caused by industries has become a serious concern throughout the world. Of all industrial sectors, the domestic products such as soaps, detergents, and food sector are the one which consumes the highest quantity of water and it is also one of the biggest producers of effluent per unit of production. Soaps and detergents were inevitable in households. Adsorption has been used as a physicochemical process over the last decades in which molecules of the solute get distributed between two phases, one of which is solid whereas the other may be liquid or gas. However, commercially available activated carbon which is widely used as the adsorbent is expensive. Higher production cost and regeneration difficulties make them unviable and made way to research on the use of non-conventional low-cost adsorbents such as neem leaves, sawdust, and teak leaves. In this study Activated Teak Leaves are used to treat the soap industry effluent and their effect on pollutant are studied. The physical and chemical characteristics of teak leaves adsorbent were analyzed such as particle size, surface area, etc. Further, characteristics of detergent wastewater were also studied to find out the contaminant level. Herewith, the adsorption study was conducted on fundamental parameters such as pH, dosage and contact time etc. From the above study and obtained results, it has been found that the percentage adsorption of phosphate from detergent wastewater such as 91.41% was achieved for 6gm of activated teak leaves adsorbent within 1hour at pH 2 and COD was removed about 92.2 % using teak leaves as adsorbent which was another important issue which was addressed. And their results are fitted in Langmuir, Freundlich models were used to describe kinetic data. Overall, the conducted study confirms the benefits for the sake of the whole environment.

This paper demonstrates use of artificial neural network (ANN) model for the evaluation of copper biosorption process using black cumin. The experimental variables (temperature, biosorbent mass, initial copper concentration, initial pH) were used as the input to the constructed neural network to predict the adsorbed amounts of copper at any time as the output. The high R 2 -values, 0.89 and 0.93 for training and testing data sets, respectively; between the network prediction and the corresponding experimental data prove that modeling the biosorption process using artificial neuron network is a satisfactory method. Thermodynamic parameters such as Gibbs free energy (ΔG°), the enthalpy (ΔH°) and the entropy change of sorption (ΔS°) were also evaluated. It was found that the biosorption process was spontaneous, favorable and exothermic in nature. The equilibrium sorption of copper ions was determined from the Langmuir equation and found to be 16.13 mg/g at 293 K. A comparison between the model results and experimental data showed that the ANN model is able to predict the removal of copper using black cumin.Keywords: artificial neural network (ANN), black cumin, copper, biosorption Bakır biyosorpsiyon işlemine Yapay Sinir Ağı (ANN) yaklaşımı ÖZ Bu makale, çörek otu kullanılarak bakır biyosorpsiyon işleminin değerlendirilmesi için yapay sinir ağı (ANN) modelinin kullanımını göstermektedir. Deneysel değişkenler (sıcaklık, biyosorbent kütlesi, başlangıç bakır derişimi, başlangıç pH'ı) çıkış olarak, herhangi bir zamanda adsorplanan bakır miktarını tahmin etmek için kurulan sinir ağında girdi olarak kullanılmıştır. Ağ tahmini ve ilgili deneysel veriler arasındaki yüksek R 2 -değerleri, eğitim ve test veri setleri için sırasıyla 0,89 ve 0,93, yapay nöron ağını kullanarak biyosorpsiyon işleminin modellemede yeterli bir yöntem olduğunu kanıtlamaktadır. Gibbs serbest enerji (ΔG°), entalpi (AH°) ve sorpsiyonun entropi değişimi (ΔS°) gibi termodinamik parametreler de değerlendirildi. Biyosorpsiyon işleminin gerçekte kendiliğinden, istemli ve ekzotermik olduğu bulunmuştur. Bakır iyonunun denge sorpsiyonu, Langmuir denklemine göre belirlenmiştir ve 293 K'de 16,13 mg/g olarak bulunmuştur. Model sonuçları ve deneysel veriler arasındaki karşılalaştırma çörek otu kullanılarak bakırın giderilebileceğini göstermektedir.Anahtar Kelimeler: yapay sinir ağı (ANN), çörek otu, bakır, biyosorpsiyon
