“…Many adsorbents such as soils, montmorillonite, magnetic porous carbon, and surface-functionalized mesoporous silica have been used to adsorb TCs from water [1,13,15,16]. In addition, previous metal-antibiotic interactions studies showed that iron could form stable complexes with TCs.…”

“…Antibiotics are widely used as human infectious disease medicines, veterinary medicines and animal husbandry growth promoters [1,2]. However, most of the antibiotics are poorly absorbed and metabolized by humans and animals after intake, so that about 30-90% of administered compounds are released into the environment [3].…”

“…might have been effective in the adsorption. According to the recent studies about removal of tetracycline, the highest adsorption amounts were observed when the acidic pH values were applied (Kang, Liu, Zheng, Qu, & Chen, 2011;Zhu et al, 2014;Liu et al, 2015). The temperature is also one of the most effective parameters in adsorption experiments.…”

Importance of the artificial intelligence in the chemical processes has been increased in the recent studies. Although biosorption is widely studied topic in chemistry, modelling of biosorption data is based on very old equations. However, use of artificial intelligence in the biosorption based studies can give important clues to researchers. For this purpose, the biosorption of tetracycline by using Posidonia oceanica from the Mediterranean Sea was studied in this study. According to classical evaluation, the data were well in line with pseudo-second order kinetic and Langmuir's isotherm. In the artificial neural network modelling, the best back propagation algorithm, optimum number of hidden neuron and optimum training:validation:testing ratio were found as Bayesian Regulation, 16 and 70:10:20, respectively. In conclusion, P. oceanica based marine waste can be used in the development of high performance biosorbents for environmental pollutants. However, it should not be forgotten that P.oceanica is a threatened species; therefore, only dead leaves accumulated in recreational area should be collected and evaluated based on the permissions of governmental authorities. The results also exhibited that artificial neural network can also be used in the modelling of the biosorption data in which it helps scientists to estimate biosorption ratio correctly under various conditions.

“…Thus, disposal and resource use the sewage sludge have aroused wide attention. Over the last decades, great efforts have been focused on the preparation of effective and low-cost carbonaceous adsorbents from a wide range of waste materials, such as plant straw, agricultural wastes, sewage sludge, and other production residues [1][2][3][4][5].…”

Abstract. We have demonstrated a facile and economical method for the synthesis of the sewage sludge-derived carbon. This product was prepared by using poly-aluminium chloride (PAC) as pore-forming agent through high-temperature pyrolysis at 900℃, and employed for the removal of phenol from water. Thermodynamic properties, textural evolution, morphological structure, and surface functional groups of product are characterized. Moreover, the total pore volumes and SSA of the residual carbon increased to 0.1727 cm 3 /g and 141.2 m 2 /g, that expanded to 2.3 times and 2.5 times compared with direct carbonized sample (0.075 cm 3 /g and 55.45 m 2 /g), respectively. The results indicated that the addition of PAC had important effect on the texture, surface properties and adsorption performance. The adsorption kinetics and isotherms studies were investigated in details to reveal that the kinetics and equilibrium adsorptions are well-described by pseudo-second-order kinetics and Langmuir isotherm model, respectively. Remarkably, the resulting adsorbent showed comparably adsorption capacity with the commercial activated carbons. Meanwhile, our method is more economical than other chemical activation methods.
