“…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.…”

“…The best isotherm model in removal studies of tetracycline was generally reported as Langmuir isotherm. The reported adsorbents are montmorillonite (Figueroa et al, 2004), bio-char , graphene oxide (Lin, Xu, & Li, 2013), tannin based cryogels and hydroxyapatite/clay (Erşan et al, 2013;Ersan et al, 2015). A comparison of adsorption capacities of other adsorbents developed for tetracycline in the literature was given in Table 8.…”

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.

In this study, the circulating fluidized bed was used to remove the Tetracycline from wastewater utilizing a pistachio shell coated with ZnO nanoparticles. Several parameters including, Tetracycline solution flowrate, initial static bed height, Tetracycline initial concentration and airflow rate were systematically examined to show their effect on the breakthrough curve and the required time to reach the adsorption capacity and thus draw the fully saturated curve of the adsorbent. Results showed that using ZnO nanoparticles will increase the adsorbent surface area and pores and as a result the adsorption increased, also the required time for adsorbent saturation increased and thus the removal efficiency may be achieved at minimum antibiotic flowrate, maximum bed height, higher antibiotic concentration, and higher airflow rate. Also, a minimum fluidization velocity correlation was developed in this study. This correlation was found to be a function of liquid velocity, bed height, particle size, and particle density. The results showed that circulating fluidized bed has a better performance and last more than two hours before the bed biomass exhausted in comparison with traditional fluidized bed.
