[ 1 ] - Disinfection byproducts in swimming pool water in Sanandj, Iran
The present study aimed to determine the concentrations of several disinfection byproducts (DBPs), including trihalomethanes (THMs), haloacetic acids (HAAs), and haloacetonitriles (HANs), in the public and private swimming pools in Sanandaj, Iran (n=16). Correlations between DBP levels with water quality parameters (free chlorine, pH, total organic carbon, temperature, number of swimmers, and gen…
[ 2 ] - Spatial distribution of fluoride in groundwater resources in selected parts of Kurdistan Province, Iran, using the geographical information system
Fluoride in drinking water has a profound effect on teeth. Since drinking water is an important source of fluoride, the evaluation of the fluoride content of water resources is necessary. Temporal variations and spatial distribution of fluoride in drinking water of some selected parts of Kurdistan Province, Iran, have been studied using geographic information system (GIS) techniques. Thus, 40 vil…
[ 3 ] - Removal of Reactive Green 19 dye from synthetic wastewater using electrocoagulation and aluminum electrodes
Textile dyeing is considered to be one of the major industrial sources of high rates of organic and aromatic compounds. Conversely, these compounds have become a significant environmental problem. Many methods have been investigated for color removal from dye-containing wastewater. In this research, the efficiency of the electrocoagulation (EC) process with aluminum electrodes in the removal of R…
[ 4 ] - Temporal and spatial variation of drinking water quality in a number of Divandareh villages, Iran: With emphasis on fluoride distribution
Fluoride is found in all water resources at different concentrations and drinking water is the major source of fluoride exposure. Thus, because of the adverse effect of fluoride in low and high concentrations, the evaluation of its content in drinking water is necessary. In the present study, the temporal variations and spatial distribution of fluoride concentrations in the drinking water of vill…
[ 5 ] - بررسی کارایی فرآیند فتوکاتالیستی حذف کروم در حضور مواد آلی از محیط آبی با استفاده از نانو ذرات TiO2 سنتز شده به روش سل ژل
Background and Aim: Widespread use of Chromium and their compounds in many industries, including plating, steel production, and wood protection and tanning leather, can result in the discharge of large amounts of pollutants to receiving waters, leading to toxic effects on human health and the environment. The aim of this study was to determine the efficiency of the photocatalytic process to remov…
[ 6 ] - وضعیت توسعه‌یافتگی و درجه برخورداری بخش بهداشت و درمان با استفاده از دو روش موریس و تاکسونومی عددی: مطالعه موردی شهرستان‌های استان کردستان

[ 8 ] - بررسی امکان‌سنجی استفاده مجدد از پساب تصفیه‌خانه فاضلاب شهر سنندج در کشاورزی
زمینه و هدف: کمبود رو به تزاید آب، رشد سریع جمعیت و نیاز به توسعه در بخش کشاورزی باعث شده که آب کالایی یک‌بارمصرف محسوب نشده و راه‌حل‌هایی جهت رفع این محدودیت از منابع آب از طریق تصفیه و بازچرخش فاضلاب‌ها به دلیل منبع ای ارزان، دائمی و قابل‌اطمینان و در دسترس و بودن سبب شده است. در این راستا قابلیت کاربرد پساب خروجی از تصفیه‌خانه فاضلاب سنندج در کشاورزی با رعایت استانداردهای تدوین‌شده جهت غ…
[ 9 ] - Synthesis and structural properties of Mn-doped ZnO/Graphene nanocomposite
Zinc oxide (ZnO) is a promising metal oxide semiconductor with various applications, especially in the photocatalytic destruction of environmental pollutants. However, this nanoparticle has some limitations, such as poor dispersion, aggregation, and a wide energy gap. As such, the doping of metal oxide semiconductor has been strongly recommended. Addition of manganese (Mn) has proven effective in…
[ 10 ] - Kinetic study of the photocatalytic degradation of the acid blue 113 dye in aqueous solutions using zinc oxide nanoparticles immobilized on synthetic activated carbon
Approximately 10-20% of the total dyes in the world is consumed in the textile industry. The present study aimed to investigate the photocatalytic activity of zinc oxide nanoparticles (ZnO) immobilized on synthetic activated carbon in the removal of the acid blue 113 dye from aqueous solutions. This experimental study was conducted in a photo-reactor with the useful volume of one liter. The effec…
