[ 1 ] - Indoor Radon Measurement in Dwellings of Khorramabad City, Iran
Introduction: Exposure to indoor radon increases the risk of lung cancer. This study examined the level of indoor radon in dwellings of Khorramabad city, by using passive alpha-track detector (CR-39) during winter of 2016. Materials and Methods: In the present study, we detected the concentration of indoor radon in 56 dwellings. A passive sampling instrument (alpha-track detector with CR-39 pol...
[ 2 ] - Improved removal of Trinitrotoluene (TNT) from contaminated soil by inducing aerobic process: kinetic and chemical byproducts
This study describes the biological degradation of TNT by using induced aeration. Three plastic reactors were used. In each reactor 3 kg of soil were used. In order to increase the porosity of the soil, sawdust was added to soil. Textile wastewater treatment plant sludge was also added to soil. TNT at the concentrations of 1000 mg/kg of soil was added thereafter. Rhamnolipid biosurfactant at th...
[ 3 ] - بررسی استفاده از فرآیند الکتروفنتون با الکترودهای آهن و گرافیت برای حذف مترونیدازول از محلول های آبی
Background : The indiscriminate consumption of antibiotics and their discharge into the environment have created serious complications. Therefore, it is necessary to remove these contaminants from the aquatic environment. The antibiotic Metronidazole is a contaminant that should be eliminated from the environment. The aim of this study was to evaluate the use of the Electro-Fenton advance...
[ 4 ] - بررسی حذف دو-کلروفنل از محیط های آبی با استفاده از فرآیند الکترو/ پرسولفات
Background : 2-chlorophenol is one of the aromatic organic compounds found in large amounts in oil and petrochemical waste waters and chemical methods such as advanced oxidation, etc are used for removal there. Among various AOPs the method derived from sulfate radicals (SO4● -) and per sulfate (S2O82-) activating with heat, UV radiation and transition metals (such as iron ions) is of interest....
[ 5 ] - 2-Chlorophenol Removal of Aqueous Solution Using Advanced Oxidation Processes Resulting from Iron/ Persulfate and Ultra Violet/ Persulfate
Background: Advanced oxidation processes are used to remove toxic aromatic compounds with low biodegradability, such as 2-chlorophenol. This study investigates the use of Sulfate (SO4-) and persulfate (S2O82-) radicals, as one of the advanced oxidation methods, to remove 2- chlorophenol from aquatic solutions. Materials and Methods: This experimental and pilot-scale study was carried out usi...
[ 6 ] - Destruction and Dechlorination of Aroclor1254 in Real Waste Transformer Oil Using Microwave Irradiation, Microwave Absorbent and Reactive Materials
Background: In this research, the decomposition of Aroclor 1254, including 20 kinds of poly chlorinated biphenyls (PCBs), in real waste transformer oil in the presence of PEG1000, NaOH, zero valent iron and H2O by microwave (MW) irradiation was studied. Methods: Central composites design (CCD) method was carried out for experimental design. The effects of microwave power levels (200- 1000 W), ...
[ 7 ] - بررسی راهکارهای بهینه سازی مصرف انرژی درایستگاه های پمپاژآب آشامیدنی روستاهای بخش مرکزی شهرستان خرم آباد در سال 1396
Abstract This study was conducted to reduce energy consumption and consumed electricity costs at drinking water pumping stations in villages located at the central part of Khorramabad city in 2017. In this study, 10 wells and pumping stations from a total of 48 wells and pumping stations in Khorramabad were selected randomly. The energy consumption, energy intensity, the effect of the capacito...
[ 8 ] - Nitrate Removal from Aqueous Solutions Using Granular Activated Carbon Modified with Iron Nanoparticles (RESEARCH NOTE)
Nitrate contamination of water resources and the growing concentration of nitrate endanger human health and the environment and considering its reduction strategies from water resources is important. The aim of this study was to investigate the possibility of removal of nitrate from aqueous solutions using granular activated carbon from grape wood coated with iron nanoparticles. The results sho...
[ 9 ] - Aniline Degradation Using Advanced Oxidation Process by UV/Peroxy Disulfate from Aqueous Solution
This study is focused on removing toxic aniline from aqueous solutions using advanced oxidation process by UV/ peroxy disulfate. In this study, the effect of various parameters including pH (3-9), the level of radiation (ultraviolet 30 watt lamp, number 2-5), peroxy disulfate dose (0.02 – 0.08 mol/l) and the initial concentration (20 – 100 mg/l) at different contact times (10 – 60 min) on the e...
[ 10 ] - Dechlorination of Polychlorinated Biphenyls in Real Waste Transformer Oil Using a Modified Household Microwave Oven in Presence of Sodium Hydroxide and Polyethylene Glycol
This research was carried out to assess the dechlorination and decomposition of Polychlorinated biphenyls (PCBs) in the real waste transformer oil using polyethylene glycol 1000/NaOH through a modified household microwave oven. To do so, the influence of polyethylene glycol (PEG) (1.5-7.5 g) and NaOH (0.3-1.5 g) under microwave (MW) power of 500 W on the dechlorination efficiency of PCBs, exist...
