Abstract Emerging and hazardous environmental pollutants like phthalic acid esters (PAEs) are one of the recent concerns worldwide. PAEs considered to have diverse endocrine disrupting effects on human health. Industrial wastewater has been reported as an important environment with high concentrations PAEs. In present study, four short-chain including diallyl phthalate (DAP), diethyl (DEP), dimethyl (DMP), (PA) were selected a substrate for anaerobic fixed film bed reactor (AnFFFBR). The...
Abstract Nowadays, the presence of antibiotics in environment has been identified as an important concern for various life cycle. Thus, this study was conducted to evaluate ciprofloxacin (CIP) adsorption efficiency onto multi-walled carbon nanotube (MWCNTs) and magnetic (MMWCNTs). In experimental study, characteristics studied adsorbents were determined using SEM, FTIR XRD methods. The effects operational parameters including contact time (10–120 min), initial concentration CIP (10–100...
In this study, the experimental data were collected in a laboratory-scale batch reactor equipped with graphite electrode as anode and an SS316 cathode. The central composite design (CCD) was selected for evaluation of effect different parameters (j = 1–8 mA/cm2, initial diazinon concentration 30–90 mg/L, pH 3–11, electrolysis time min) their interactions on electrochemical degradation diazinon. results showed that removal COD reached 87.6% 77.81%, respectively. kinetic studies indicative...
Bisphenol A (BPA) is one of the endocrine disrupting compounds that has significant estrogenic effects and if it not treated, will enter into water resources cause irreparable environmental problems.Thus, this study aims at determining efficiency heterogeneous Fenton-like process using modified magnetic nanoparticles with sodium alginate in removing BPA from aquatic environments.In experimental research, factors including pH (3-9), contact time (10-180 min), initial concentration catalyst...
The releasing of dye-contained effluents has become an objectionable problem in these decades. Thus, the aim present work was to evaluate potential acid-treated Clinoptilolite for Methylene Blue (MB) dye removal from aqueous solution. In this experimental-lab study, adsorption onto carried out batch system. Brunauer-Emmet-Teller (BET) analysis, Scanning Electron Microscopy (SEM), XRF analysis and X-ray diffraction (XRD) were utilized characterize Clinoptilolite. effect some parameters on...
