“…After four cycles of regeneration (fifth adsorption cycle), the adsorption capacity for TC and OTC declined by about 50 and 30%, respectively. The decrease in adsorption capacity was higher compared to other studies for different adsorbent material . This might be due to the narrower pore structure of the NZ02 than other materials used .…”

The persistence of antibiotics in sewage wastewater treatment plants in recent years has emerged as a serious issue. This study therefore evaluated three types of natural zeolites (i.e., NZ01, NZ02, and NZ03) for the removal of selected antibiotics namely tetracycline (TC) and oxytetracycline (OTC) from aqueous solution. The physical and chemical properties of the natural zeolites were characterized using various analytical techniques and the antibiotic removal studies were carried out in a batch adsorption experiment evaluated at various experimental conditions. The highest adsorption capacity was 62.5 and 76.3 mmol/g for TC and OTC, respectively, observed for NZ02 at pH values between 7 and 8. The adsorption of TC and OTC followed the Langmuir and Temkin isotherm models, respectively, whereas the adsorption kinetic data obeyed the Elovich kinetic model. The regeneration study on NZ02 indicated that it can still remove TC and OTC after five adsorption/desorption cycles. The removal efficiency of TC and OTC also improved from approximately 5-39 and 28%, respectively, by addition of NZ02 during the coagulation/flocculation process. These results thus demonstrated the applicability of the natural zeolites, especially NZ02, for the removal of TC and OTC from aqueous solution; hence the potential for the application in sewage treatment process for removal of antibiotics through either conventional adsorption/desorption or adsorptive coagulation/flocculation (ACF) process.

“…We also wanted to give all raw data in these tables and figures so that the readers can see them. The calculated adsorption capacity in this study was slightly higher than those of other studies by using different adsorbents (Sithole & Guy, 1987;Kang, Liu, Zheng, Qu, & Chen, 2010;Liao et al, 2013;Zhang et al, 2014;Ersan, Guler, Acikel, & Sarioglu, 2015). The best isotherm model in removal studies of tetracycline was generally reported as Langmuir isotherm.…”

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.

A large variety of microporous polymers such as hypercrosslinked polymers (HCPs), conjugated microporous polymers (CMPs), porous aromatic frameworks (PAFs) or polymers of intrinsic microporosity (PIMs) have attracted a growing technological interest for applications in gas storage [3,4], catalysis [5,6], and separations [7][8][9].…”
