“…It is a powerful optimization method which has recently been used for other optimization processes (Şahan et al 2010). The reasons for its popularity are that it does not require additional consumption of chemicals for each parameter, nor is it especially time-consuming, costly or labor-intensive (Chi et al 2012, Myers and Montgomery 2002, Öztürk and Şahan 2015, Şahan and Öztürk 2014). This method is based on the fi t of mathematical models (linear, square polynomial functions, and others) to the experimental results generated from the designed experiment and confi rmation of the model obtained via statistical techniques.…”

Abstract:Removal of mercury(II) (Hg(II)) from aqueous media by a new biosorbent was carried out. Natural Polyporus squamosus fungus, which according to the literature has not been used for the purpose of Hg(II) biosorption before, was utilized as a low-cost biosorbent, and the biosorption conditions were analyzed by response surface methodology (RSM). Medium parameters which were expected to affect the biosorption of Hg(II) were determined to be initial pH, initial Hg(II) concentration (C o ), temperature (T (°C)), and contact time (min). All experiments were carried out in a batch system using 250 mL fl asks containing 100 mL solution with a magnetic stirrer. The Hg(II) concentrations remaining in fi ltration solutions after biosorption were analyzed using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). Based on the RSM results, the optimal conditions were found to be 5.30, 47.39 mg/L, 20°C and 254.9 min for pH, C o , T (°C), and contact time, respectively. Under these optimal conditions, the maximum biosorbed amount and the biosorption yield were calculated to be 3.54 mg/g and 35.37%, respectively. This result was confi rmed by experiments. This result shows that Polyporus squamosus has a specifi c affi nity for Hg ions. Under optimal conditions, by increasing the amount of Polyporus squamosus used, it can be concluded that all Hg ions will be removed.

“…Optimization of MB adsorption study was finalized using central composite design (CCD), a sub-program of RSM, through Design-Expert (version 12.0) software. The response can be associated with the operating parameters by linear or quadratic models (Ozturk & Sahan, 2015). Seventeen experimental runs were carried out to develop the correlation between the functional variables of Mg-PKS biochar composite to the removal of MB from an aqueous solution.…”

This study investigates the properties and potential application of Mg-PKS biochar composite for methylene blue solution (MB) adsorption. The Mg-PKS biochar composite was developed from palm kernel shell biochar via steam activation followed by MgSO4 treatment and carbonization. The effect of process parameters such as solution pH (4-10), contact time (30-90 min) and adsorbent dosage (0.1-0.5 g) were investigated via central composite design, response surface methodology. Results revealed that the Mg-PKS biochar composite has irregular shapes pore structure from SEM analysis, a surface area of 674 m2g-1 and average pore diameters of 7.2195 μm based on BET analysis. RSM results showed that the optimum adsorption of MB onto Mg-biochar composite was at pH 10, 30 min contact time and 0.5 g/100 mL dosage with a removal efficiency of 98.50%. In conclusion, Mg treatment is a potential alternative to other expensive chemical treatment methods for biochar upgrading to the adsorbent.
