A simple, fast, and low-cost analytical procedure was developed for trace-level determination of inorganic vanadium species by dispersive liquid–liquid microextraction in combination with spectrophotometry. Vanadium in pentavalent form, V(V), was quantitatively extracted into organic phase as 4-(2-pyridylazo)-recorcinol (PAR) complex in the presence of N-cetyl-N,N,N-trimethyl ammonium bromide (CTAB) as counter-ion. Vanadium (IV) was masked with 1,2-diaminocyclohexanetetraacetic acid to allow speciation analysis. Total vanadium was determined after oxidation of V(IV) to V(V). The main factors affecting preconcentration and spectrophotometric detection of vanadium species such as pH, concentration of PAR and CTAB, the type and volume of the extraction, and disperser solvents were optimized. The limit of detection and enhancement factor obtained under optimum conditions were found to be 0.06 μg L?1 and 98, respectively. Relative standard deviations for V(IV) and V(V) at 3.0 μg L?1 were less than 2.4%. The presented procedure was applied to environmental water samples for selective determination of vanadium species. Moreover, the method was applied to determination of vanadium in edible salt samples, due to its applicability in high-NaCl-containing solutions. The validity of proposed method was proven by spike recovery experiments and also independent analysis by inductively coupled plasma mass spectrometry. 相似文献

Early diagenetic processes control the behavior, and more specifically the dissolved‐solid phase distribution of heavy metals in sediments. The depth distribution of Co, Mn, Cu, Zn, Ni, and Fe in sediment were determined in box cores from the Black Sea. The sequential analyses results of these metals indicate contrasting behavior of Mn and Co during early diagenesis, consistent with their respective chemistries and particle‐associations. The profiles of extractable trace metals in the cores are clearly related to sediment type or depositional environment. Topmost sections of the profiles for these elements are generally similar, i.e. rapid decrease in concentration below the sediment surface. 相似文献

Electrocoagulation of some reactive dyes: a statistical investigation of some electrochemical variables 总被引:8,自引:0,他引:8
In this study, the decolorization of strong colored solutions containing the reactive textile dyes by electrocoagulation was investigated. The experiments were statistically designed and carried out according to a 2(4) full factorial design with two replicate and four center points. This design was extended with eight additional axial points. Then, the non-linear regression was applied on the data by using MINITAB software. The variables chosen for this work are mixing rate, cell voltage, electrolysis time and current density. Results showed that the effective variables on decolorization process are cell voltage, electrolysis time and current density. In addition, to determine the effect of dye and electrode type on decolorization, the additional experiments were carried out. It was determined the dye and electrode type are important on the decolorization process. 相似文献

The effects of solar radiation and temperature on bacterial die-off rates in Black Sea coastal waters using total coliform as the indicator organism were studied. Coliform die-off experiments were carried out in seawater samples collected along the coastline. The experiments were conducted in beakers filled with seawater that were kept at constant temperatures and exposed to solar radiation. The membrane filter technique was used for the coliform analysis. Temperature ranging between 9 and 26 degrees C and solar radiation between 20 and 60 cal/cm(2) h were tested. Experiments in the dark were also conducted to isolate the effect of solar radiation from the other factors and, furthermore, to determine the effect of temperature on bacterial die-off. The solar radiation was found to be the most significant factor affecting the mortality of coliform bacteria. 相似文献

In this study, perceptions, needs, expectations and participation levels in the park management of residents of the K?z?lda? National Park were investigated. It was focused on especially how residents’ livelihood was affected by establishment and management of K?z?lda? National Park. It was examined why residents do not support protection efforts. Research data were obtained with the help of a survey form prepared to determine the perceptions of residents living in the national park. For the analyses of obtained data, statistics package program (SPSS 20) was used and also independent-samples t test and one-way analyses of variance were applied. As a result, the most important negative effects were loss of income and changes in traditional lifestyle. The most affected group from these negative effects was the ones dealing with animal husbandry. For the sustainable management and protection of national park, sense of belonging should be brought to residents so as to increase participation, traditional lifestyle of residents should be conserved and new sources of income should be generated for residents. To improve the participation of residents in national park management, community engagement mechanisms can be used as a tool. 相似文献

One of the most important hydrogeologic problems in and adjacent areas of evaporitic formations is severe quality degradation
of groundwaters. These kinds of groundwaters contain high content of dissolved solids and generally have some limitations
for use. Tatlicay basin (north-central Turkey) is an example to effects of the evaporites on groundwater quality in the adjacent
alluvium aquifer. Gypsum and anhydrites in the two evaporite formations (Bayindir and Bozkir) effect of the groundwater quality
in the alluvium adversely, by dissolution of the evaporites by surface drainage and infiltration into the alluvium aquifer
(widespread effect) and by infiltration of low quality gypsum springs (local effect) into the aquifer. Evaporitic formations
significantly increased EC, TDS, Ca and SO4 parameters in the alluvium aquifer in the central and downstream regions. EC has increased roughly from 500–800 to 1,700–2,000 μS/cm,
Ca has roughly increased from 3–4 to 10 meq/l, SO4 has increased 0.5–1 to 11–12 meq/l. Consequently, three clusters were distinguished in the basin; (1) nonevaporitic waters
in low TDS, Na, Ca, Mg, Cl and SO4, (2) diluted waters in high TDS and relatively high Cl, moderate-relatively high Na, Ca, Mg, SO4, (3) gypsum springs in highest TDS, Ca, SO4, but moderate Mg and low Na, Cl. 相似文献
