Multi-walled carbon nanotubes (CNTs) can affect plant phenotype and the composition of soil microbiota. Tomato plants grown in supplemented with CNTs produce two times more flowers fruit compared to control soil. The effect on microbial community CNT-treated is determined by denaturing gradient gel electrophoresis pyrosequencing analysis. Phylogenetic analysis indicates that Proteobacteria Bacteroidetes are most dominant groups relative abundances Firmicutes found increase, whereas...
The present study evaluates the groundwater quality for drinking and agricultural purposes determines physicochemical characteristics of in Sistan Baluchistan province Iran. In order to investigate water quality, sampling was done 654 open dug wells, chemical parameters were analyzed, index determined. this regard, Langelier saturation (LSI), Ryznar Stability (RSI), Puckorius scaling (PSI), Larson–Skold (LS), Aggressiveness (AI) considered determine suitability industrial purposes. Finally,...
Developing a water quality index which is used to convert the dataset into single number most important task of monitoring programmes. As setup based on different local obstacles, it not feasible introduce definite reveal level.In this study, an innovative software application, Iranian Water Quality Index Software (IWQIS), presented in order facilitate calculation dynamic weight factors, will help users compute cases where some parameters are missing from datasets.A containing 735 samples...
The present study was conducted to evaluate the groundwater quality and its suitability for irrigation purpose through GIS in villages of Chabahr city, Sistan Baluchistan province Iran. This cross-sectional carried out from 2010 2011 1-year-monitoring period. water samples were collected 40 open dug wells order investigate quality. Chemical parameters including EC, SAR, Na+, Cl-, pH, TDS, HCO3- IWQI analyzed. In calculate index subsequent five (EC, ) utilized. Among total analyzed IWQI, 40%...
The synthesis of compounds with an excellent adsorption capability plays essential role to remove contaminants such as phthalic acid esters (PAEs) potential carcinogenic characteristics from different food products. In this context, for the first time, a novel adsorbent (MWCNT-Fe3O4/Ag) was synthesized by using iron (magnetic agent), and silver (catalytic surface enhancer agent) further approach in magnetic SPE-GC/MS method determining PAEs carbonated soft drink samples. limit detection...
Antibiotics have been increasingly used for veterinary and medical purposes. The overuse of these compounds purposes can pollute the environment, water resources in particular. Tetracycline, among other forms antibiotics, is one most applied antibiotic aquaculture medicine. present study aimed to tack traces tetracycline effluents municipal hospital wastewater treatment plants, surface groundwater finally drinking provided from resources. samples were taken Fasha-Foyeh Dam, wells located at...
The aims of this study were to assess and analysis drinking water quality Chabahar villages in Sistan Baluchistan province by index (WQI) investigate the stability subjected area. results illustrated that average values LSI, RSI, PSI, LS, AI was 0.5 (±0.34), 6.76 (±0.6), 6.50 (±0.99), 2.71 (±1.59), 12.63 respectively. calculation WQI for groundwater samples indicated 25% could be considered as excellent water, 50% classified good category showed poor category.
A central composite design using response surface methodology was applied for the experimental and optimization of fluoride adsorption on an activated carbon derived from calcium chloride-modified Crocus sativus leaves (AC-CMCSL). Fluoride removal efficiency as function independent variables, such initial concentration, pH, adsorbent dose, time has been investigated. The maximum percentage at optimum conditions (initial concentration = 6.5 mg L−1, pH 4.5, dose 15 g L−1 70 min) 85.43%. By...
In this study, a central composite design (CCD) was used for modeling and optimizing the operation parameters such as pH, initial tetracycline persulfate concentration reaction time on degradation using sono-activated process. The effect of temperature, kinetics mineralization, were also investigated. results from CCD indicated that quadratic model appropriate to fit experimental data (p < 0.0001) maximum 95.01 % predicted at pH = 10, 4 mM, 30.05 mg/L, 119.99 min. Analysis response surface...
In this study, at first were prepared novel multi-walled carbon nanotubes modified with catalytic nanoparticles of iron oxide and silver (MWCNTs-Fe3O4/Ag) by mixing the magnetic particles. Due to their excellent absorption desorption capability towards hydrophobic compounds, MWCNTs used as adsorbent solid-phase extraction (MSPE) extract phthalate acid esters (PAEs). Our results showed highest concentration bis(2-ethylhexyl)phthalate (DEHP) which is much higher than standard level in four...
This cross-sectional study was conducted on the drinking water resources of city Jolfa (East Azerbaijan province, Iran) from samples taken 30 wells. Calcium hardness, pH, total alkalinity, TDS, temperature and other chemical parameters were measured using standard methods. The Langelier, Rayzner, Puckhorius aggressive indices calculated. results showed that Reynar, Puckorius, Larson-skold 1.15 (± 0.43), 6.92 0.54), 6.42 0.9), 0.85 0.72) 12.79 0.47), respectively. In terms classification, 30%...
