Enhancing of Copper (II) Adsorption Efficiency by Mixing Plantain and Orange Peelings as Bio-Sorbent Support

Migration study of phthalates from non-food plastic containers used in food preservation

“…Validation of models is done through the calculation of absolute average deviation (AAD), adjusted coefficient of determination (R 2 aj ), bias factor (B f ) and exactitude factor (Af 1 ) according to Eqs. (4) , (5) , (6) , (7) respectively [ 28 ]. where Y exp is the experimental value; Y cal is the calculated value; n is the number of experiments.…”

“… where Y exp is the experimental value; Y cal is the calculated value; n is the number of experiments. These parameters have to fulfill the following conditions [ 28 ]: AAD has to be as close to zero as possible R 2 aj has to be greater than 0.85 Bf and A f 1 have to be between 0.75 and 1.2. …”

“…Hence, rather than studying the effect of each factor separately, it could be interesting to consider interaction between factors. To study the effects of factors simultaneously, experimental design modeling was found to be an important tool for reducing the number of experiments and exhibiting interaction between influencing parameters [ 28 ].…”
