Activated carbon（AC）were prepared from lignin by chemical activation with sodium hydroxide（NaOH）. The influence of activation temperature，activation time and impregnation ration on the BET surface areas were investigated. Based on the central composite design (CCD) and response surface methodology(RSM)，the optimized technological parameters were as follows: temperature 751°C， time 57min and impregnation ration 2.06, BET surface areas was up to 1437.20 m2/g.The adequacy of the model equation for predicting the optimum response values was verified effectively by the validation.

Distillery industry is recognized as one of the most polluting industries in India with a large amount of annual effluent production. In this present study, the optimization of electrochemical treatment process variables was reported to treat the color and COD of distillery spent wash using Ti/Pt as an anode in a batch mode. Process variables such as pH, current density, electrolysis time, and electrolyte dose were selected as operation variables and chemical oxygen demand (COD) and color removal efficiency were considered as response variable for optimization using response surface methodology. Indirect electrochemical-oxidation process variables were optimized using Box-Behnken response surface design (BBD). The results showed that electrochemical treatment process effectively removed the COD (89.5%) and color (95.1%) of the distillery industry spent wash under the optimum conditions: pH of 4.12, current density of 25.02 mA/cm2, electrolysis time of 103.27 min, and electrolyte (NaCl) concentration of 1.67 g/L, respectively.

Ultrasonic Assisted Extraction

Moringa oleifera is considered one of the most useful plants in the world because it's rich in bioactive substances, which employing on modern medical treatment, also can be used for many fields: pharmaceutical, food and cosmetics purposes. In this study, the response surface methodology (RSM) based on a Box–Behnken design (BBD) was employed to optimize the extraction time (X1: 20–60 min), extraction temperature (X2: 15–45 °C) and solvent-solid ratio (X3: 5–7 ml/g), to obtain a high crude of flavonoids yield from Moringa oleifera Leaves by ultrasonic-assisted extraction technique (UAE). The optimum conditions were an extraction time 23 (min), extraction temperature 44 (°C) and solvent-solid ratio 5.05 (ml/g). Under these conditions, the experimental yield was 72.65 (mg ER/g), well matched with the predicted yield 74.34 (mg ER/g) with the coefficients of determination (R2= 0.9861), thus indicating the suitability of response surface methodology in optimizing the ultrasound-assisted extraction of flavonoids from Moringa oleifera Leaves.
