Overseeded perennial ryegrass (Lolium perenne L.) turf on dormant bermudagrass (Cynodon dactylon Pers. L) in transitional climatic zones (TCZ) experience a severe reduction its growth due to cold stress. Primary plant nutrients play an important role the stress tolerance of plants. To better understand overseeded under TCZ, three-factor and five-level central composite rotatable design (CCRD) with regression model was used study interactive effects nitrogen (N), phosphorus (P), potassium (K)...
This study aims to explore the stability of TiO2 nanoparticles in soil suspensions and their transport behavior through real columns. A classical filtration theory was used describe behaviors nanoparticles. The results illustrated that could remain suspended even after settling for 8 d. At comparatively higher dissolved organic matter (DOM) low ionic strength (IS) containing soils, considerable portion (32–34%) observed sedimentation experiments 24 h. In addition, zeta potential (ZP) as a...
In this study, removal of Ni and Cu ions from aqueous media was assessed by the adsorption Al2O3 nanoparticles (ANPs), with surface modification natural organic matter (NOM). The obtained materials (NOM–ANPs) were characterized Fourier transform infrared spectroscopy. Then, batch methods carried out as a function contact time, adsorbate concentration, pH temperature. Kinetic experiments revealed that pseudo-second-order model exhibited best correlation data, estimated maximum capacity could...
ABSTRACT Increasing temperatures cause the weather to become more severe. Studying how heatwaves (HWs) impact individual heat exposure and susceptibility is vital for building climate change mitigation adaptation measures. So, this study explores of HWs on susceptibility. The assessment was based highly complex topographic region contribution in Republic Armenia (RA) using data from 16 meteorological stations extended warm season (May–September). We developed a regional HW catchment program...
The transport behavior of TiO 2 nanoparticles (TNPs) through different soil columns as well their effects on the mobility Cu was systematically examined.Results showed that a constant concentration plateau (C f /C o %) achieved at experimental breakthrough curves, ranging from 89%, 53%, and 60% for soils Gölbaşı (Gö), Hacettepe (Ha), Batikent (Ba) respectively.While Brownian diffusion predominant mechanism TNPs removal in all three media, gravitational sedimentation also played significant...
The interaction of Zn and Cu with dissolved organic matter (DOM) is a significant physicochemical process affecting their sorption as well mobility in soil. objective this study was to examine the influence DOM from corn straw on by loess through batch adsorption technique. isotherms could be described Freundlich equation, partition distribution coefficient (k) presence reduced 86% for 58% Cu, compared control receiving no DOM, suggesting that had stronger inhibitory effect than Cu. In...
In this work, TiO 2 nanoparticles (TNPs) were used as an absorbent to remove Pb(II) and Ni(II) from aqueous solution.The effect of pH, ionic strength (IS), humic acid (HA), contact time, foreign ions temperature on the adsorption onto TNPs examined by batch technique.The results showed that was dominated outer-sphere surface complexation at pH < 6.0, whereas, inner-sphere main absorption mechanism > 6.0.The maximum capacity calculated a Langmuir model 40.00 26.32 mg g -1 , respectively 303...
Kaonilite‐supported zero‐valent iron (ZVI‐K) was employed with H 2 O to build a Fenton‐like system. Batch tests were conducted explore the characteristics and mechanisms of system for nitrobenzene (NB) degradation. The results showed that ZVI‐K an efficient Fenton catalyst several advantages, including extended pH range 7.02, near‐neutral final treated water, excellent stability reusability. NB degradation affected by initial pH, concentration, dose. For concentration 38.6 mg/L, their...
In this study, removal of Cd from aqueous media by the adsorption TiO 2 nanoparticles (TNPs), with surface modification humic acid (HA) was assessed.Results showed a linear increase coating percentage 100-HA to 250-HA but no significant difference between HA coated TNPs prepared at 250 and 350 mg L -1 due an extremely narrow band gap.The obtained materials (HA-TNPs) were characterized Fourier transform infrared spectroscopy UV-visible spectrophotometer.Then, batch techniques carried out...
The objective of this research was to develop a spectrophotometric technique for estimation concentration dissolved organic matter (DOM) from sediment. results showed that the absorbance 272nm is good surrogate DOM. In addition, absorption DOM confirmed be independent pH values ranging 3.0 11. Compare chemical oxygen demand method and TOC–analyzer, correlation using UV– visible very straightforward, needs much smaller sample volume, shows reproducibility. (272nm) increased with increasing...
