In this research, graphene oxide (GO) as an adsorbent was used to remove norfloxacin and ceftriaxone antibiotics from aqueous solutions. All environmental factors affecting removal (e.g., pH, mass, contact time, concentration) were optimized in a discontinuous system. The design of experiments the optimization variables carried out using response surface method (RSM). results analysis variance (ANOVA) regression coefficients quadratic terms indicated that responses significantly affected by all studied ( P < 0.05). Also, polynomial model corresponded empirical data with high coefficient determination (i.e., R 2 ˃ 0.99 for both antibiotics). Besides, adjusted (R -adj 0.98 antibiotics) close values, indicating good acceptable statistical model. According results, optimal GO occurs conditions pH 8, 0.034 g sonication time 20 min, concentration 25 mg L −1 . these conditions, maximum efficiencies equal 95.87% 98.64%, respectively. recovered five adsorption/desorption processes, efficiency declined very slightly after cycles. Therefore, it is concluded efficient removing environments.

This paper investigated the performance of electrochemical treatment technique in removing chloride from saline wastewater (brine) with critical objective purifying wastewater, evaluated efficacies selected mathematical models and particular attention to polynomial regression as a follow-up previous studies. The wastewaters were prepared subjected using developed carbon–resin (anode) aluminium (cathode) electrodes. Electrochemical synthesised (between 10 x 10^3 mg/l 40 chloride) was conducted on laboratory scale. influences or picked-out operational factors functioning efficacy purification process monitored fractional factorial experiments. Three formulated Microsoft Excel Solver statistically. study revealed that current, time interval distance between electrodes significant vital impacted brine. negative special effects brine separation electrodes, pH, depth electrode, initial primary concentration flow discharge rate wastewater. performances predicting average errors 2.99 %, 2.97 % 2.94% accuracy 97.01 97.03 97.06 for Models A, B C, respectively. It concluded carbon-resin is efficient predicted well.
