Advanced oxidation and mineralization of simazine using Fenton's reagent

Sonophotocatalytic (42kHz) degradation of Simazine in the presence of Au–TiO2 nanocatalysts

“…1) is a triazine based synthetic pesticide which is the second largest one used to control the pest in the agricultural lands since 1956 [2,[6][7][8]. The maximum solubility of Simazine in water is 5 mg/L [9], the excessive addition (or the undissolved quantity) of the Simazine in the agricultural lands was dissolved during the rainy season and the running water carries the Simazine from one end to the other end which tends to cause the environmental aquatic pollution. Arias-Estévez et al [10] found that only a minor fraction of Simazine (0.1%) is effective for the pest killing action and the remaining quantity enters into the environment which causes the soil, air and water pollution.…”

Evaluation of electro-oxidation of biologically treated landfill leachate using response surface methodology

“…Response surface methodology (RSM), a multivariate technique which mathematically fits the experimental domain studied in the theoretical design through a response function [22], is then proposed to solve these problems [17][18][19][20][21]. The main types of RSM designs include three-level factorial design, central composite design (CCD), Box-Behnken design and D-optimal design [17][18][19]23]. As one of the RSM designs, Box-Behnken design is known as a modified central composite experimental design [17][18][19]23].…”

As one of the RSM designs, Box-Behnken design is known as a modified central composite experimental design [17][18][19]23]. It is an independent, rotatable quadratic design with no embedded factorial or fractional factorial points in which the variable combinations are at the midpoints of the edges of the variable space and at the center [17][18][19]23].…”

A comparison between Box-Behnken design and other RSM designs has demonstrated that Box-Behnken design is slightly more efficient than CCD, but much more efficient than the three-level full factorial designs [19].…”

“…A comparison between Box-Behnken design and other RSM designs has demonstrated that Box-Behnken design is slightly more efficient than CCD, but much more efficient than the three-level full factorial designs [19]. Moreover, it requires fewer experiments than other RSM designs with the same number of factors [17][18][19]23]. For example, only 15 runs are needed for a three-factor experimental design.…”
