Application of response surface methodology for the optimization of polycyclic aromatic hydrocarbons degradation from potable water using photo-Fenton oxidation process

Optimization of Endo-Pectinase and Pectin Lyase Production from Wheat Bran by Bacillus pumilus using Response Surface Methodology

“…When the R 2 values are less than 0.75, models generally show an inadequate definition of experimental data. The determination coefficient for a good model fit should be at least 0.80 [25]. The coefficient of variation (CV=8.81%) for the endo pectinase activity was relatively low.…”

“…The adequacy of a model can be judged using the diagnostic plots such as the predicted versus actual value plot (Figures 1a and 2a) [27]. When Figures 1a and 2a are examined, it was understood that there was a linear relationship between the predicted and actual values and models were adequate [25]. The correlation coefficients between the actual and predicted values were 0.9820 and 0.9020 for the endopectinase activity and pectin lyase activity, respectively.…”

Step by step procedures: Degradation of polycyclic aromatic hydrocarbons in potable water using photo-Fenton oxidation process

“…For a good validation, the correlation coefficient for calibrations curves ( R 2 ) must be more than 0.95. Researchers may refer on calibration curves of 17 USEPA-PAHs reference standards as per documented in Abd Manan et al [26] .…”

“…To sum up, the prescribed method aforementioned above was a recommended steps on the photo-Fenton oxidation process for the degradation of PAHs in potable water conducted by Abd Manan et al [26] . The optimization products and outcomes were presented by [26] .…”

“…To sum up, the prescribed method aforementioned above was a recommended steps on the photo-Fenton oxidation process for the degradation of PAHs in potable water conducted by Abd Manan et al [26] . The optimization products and outcomes were presented by [26] . Authors are hoping that the procedures will be a helpful guide for researchers to conduct water research experiment especially for advanced oxidation processes with some adjustment accordingly wherever necessary.…”
