“…Therefore, the EC method is classified as a green technology for water and wastewater treatment (Neoh et al, 2016). It has been well documented that EC technology is able to remove as much as 95-99% of various pollutants within a relatively short treatment time (Gao et al, 2010;Ricordel et al, 2014;Hashim et al, 2017b;Nariyan et al, 2018). It has been successfully used to purify water of pathogens (Ricordel et al, 2014), strontium (Nur et al, 2017), heavy metals (Hashim et al, 2017c;Martín-Domínguez et al, 2018), phosphate (Behbahani et al, 2011;Attour et al, 2014), and organic matter (Vepsäläinen et al, 2012).…”

“…RSM is an effective and flexible experimental design methodology for modeling and analyzing a problem in which the response is under the influence of several variables [ 25 , 26 ]. After performing the designed experiments, the procedure of response analysis is carried out and the presented model is analyzed by general statistical tests, such as Fisher’s statistical test (F-test).…”

The growing use of carbon nanotubes (CNTs) in a plethora of applications has provided to us a motivation to investigate CNT synthesis by new methods. In this study, ultrasonic-assisted chemical vapor deposition (CVD) method was employed to synthesize CNTs. The difficulty of controlling the size of clusters and achieving uniform distribution—the major problem in previous methods—was solved by using ultrasonic bath and dissolving ferrocene in xylene outside the reactor. The operating conditions were optimized using a rotatable central composite design (CCD), which helped optimize the operating conditions of the method. Response surface methodology (RSM) was used to analyze these experiments. Using statistical software was very effective, considering that it decreased the number of experiments needed to achieve the optimum conditions. Synthesis of CNTs was studied as a function of three independent parameters viz. hydrogen flow rate (120–280 cm3/min), catalyst concentration (2–6 wt %), and synthesis temperature (800–1200 °C). Optimum conditions for the synthesis of CNTs were found to be 3.78 wt %, 184 cm3/min, and 976 °C for catalyst concentration, hydrogen flow rate, and synthesis temperature, respectively. Under these conditions, Raman spectrum indicates high values of (IG/ID), which means high-quality CNTs.

Groundwater is one of the most important natural resources in the world and plays a very important role in the supply of drinking water. Fluoride is probably one of the most common groundwater pollutants in the world for various reasons (structure of soil and rocks, etc.). The concentration of fluoride in groundwater above 1.5 mg/L begins to pose some risks to human health. Various conventional techniques such as adsorption, ion exchange, reverse osmosis, nanofiltration, precipitation have been developed for the removal of fluoride from water. However, they have several limitations, such as posttreatment re-treatment, less efficiency and higher installation costs. The electrocoagulation process is an effective technology for fluoride removal within conventional techniques. In this study, fluoride removal technologies are emphasized, and the studies done in this field are examined. The aim of this study is to investigate the advantages of electrocoagulation method in fluoride removal and to compare electrocoagulation process with other treatment technologies.
