BACKGROUND Discharge of grey wastewater into the ecological system causes the negative impact effect on receiving water bodies. METHODS In this present study, electrocoagulation process (EC) was investigated to treat grey wastewater under different operating conditions such as initial pH (4-8), current density (10-30 mA/cm2), electrode distance (4-6 cm) and electrolysis time (5-25 min) by usi...

Fusarium mycotoxins deoxynivalenol (DON) and zearalenone (ZEN) are the mostcommon contaminants in cereals worldwide, causing a wide range of adverse health effects onanimals and humans. Many environmental factors can affect the production of these mycotoxins.Here, we have used response surface methodology (RSM) to optimize the Fusarium graminearumstrain 29 culture conditions for maximal toxin p...

A simple, sensitive, precise, accurate, and robust, high-performance liquid chromatographic method has been developed to simultaneously estimate Metformin (MET) Dapagliflozin (DAPA) in pharmaceutical formulation. Design of experiments (DoE) was applied for multivariate optimization the experimental conditions RP-HPLC method. risk assessment performed identify critical parameters. The mobile pha...

background nowadays, adsorption techniques are widely used to remove certain classes of pollutants from water. objectives the aim of this study was to remove ametryn from water solutions by natural zeolite nanoparticles from the semnan region of iran. materials and methods for this purpose zeolite nanoparticles were synthesized from natural zeolite using planetary ball-mill. the zeolite nanopar...

Lysine-functionalized layered double hydroxides (LDHs) controllable fabrication based on Box-Behnken Design (BBD) model was investigated in this study. Ly @ FeZn presented stable and efficient removal performance for Ciprofloxacin (CIP) removal. Characterizations analysis batch tests results showed that had significantly different adsorption towards CIP Ofloxacin (OFL). The highest capacity of ...

Response surface methodology (RSM) was applied to optimize the effects of extraction parameters including time, power, temperature and liquid-to-solid ratio on peony seed oil yield. Box-Behnken design (BBD) employed for optimization in yield that extracted assisting by ultrasonic while petroleum ether as solvent. The chemical composition under optimal condition ultrasonic-assisted extract metho...

The objective of the present work was to optimize the formulation of fast disintegrating tablets (FDTs) of ondansetron HCl containing novel superdisintegrants, possessing sufficient mechanical strength and disintegration time comparable to those containing crospovidone or croscarmellose sodium. The FDTs were formulated using a novel superdisintegrant (chitosan-alginate (1:1) interpolymer comple...

Ethanol production strategy was studied using multiple strain microbes from microwave irradiation (MI) pretreated sago waste. Sago waste (SW) was MI-pretreated for reducing sugars production using 2 heating media (water and sulfuric acid) under pretreatment conditions including MI power, pretreatment duration, and solid loading. When water was used, the pretreatment parameters were optimized us...

The application of high-potential thermotolerant yeasts is a key factor for successful ethanol production at high temperatures. Two hundred and thirty-four yeast isolates from Greater Mekong Subregion (GMS) countries, i.e., Thailand, The Lao People's Democratic Republic (Lao PDR) and Vietnam were obtained. Five thermotolerant yeasts, designated Saccharomyces cerevisiae KKU-VN8, KKU-VN20, and KK...
