4-vinyl pyridine (4-VP) based hydrogels with 2-hydroxyethylmetacrylate (HEMA) and magnetic composites were prepared and tested for use in the removal of UO(2)(2+) and Th(4+) ions from aqueous environments. It was found that the absorption of these metal ions from aqueous environments decreased with an increase in the amount of HEMA contained within p(4-VP-co-HEMA) hydrogels between 0.498?mmol for pure p(4-VP) and 0.027?mmol for pure p(HEMA). The characterization of the hydrogels was determined by swelling experiments, FT-IR and thermal analysis. The effects of initial metal ion concentration, hydrogel amount and the temperature of the medium on absorption of the ions were investigated. Langmuir and Freundlich isotherms were constructed for the absorption of UO(2)(2+) and Th(4+). Both isotherms demonstrated that these metal ions complied with monolayer absorption kinetics. 相似文献

Lignite powered electric generation plants result in increasing environmental problems associated with gaseous emissions and
the disposal of ash residues. Especially, low quality coals with high ash content cause enormous quantities of both gaseous
and solid fly ash emissions. The main problem is related to the disposal of fly ash, which, in many cases, contains heavy
metals. It is known that toxic trace metals may leach when fly ash is in contact with water. In this study, fly ash samples
obtained from the thermal power plant in the town of Can in Turkey were investigated for leachability of metals under different
acidic and temperature conditions. The experimental results show that a decrease in pH of the leachant favors the extraction
of metal ions from fly ash. A significant increase in the extraction of arsenic, cadmium, chromium, zinc, lead, mercury, and
selenium ions from the ash is attributed to the instability of the mineral phases. These heavy metals concentrations increase
with respect to increasing acidic conditions and temperature. Peak concentrations, in general, were found at around 30°C. 相似文献

We report on two cases with partial trisomy 1q syndrome. One case was a mid-trimester fetus with multiple malformations that was prenatally diagnosed with a de novo distal partial trisomy 1q. Prenatal ultrasound at 24th gestational week demonstrated the presence of cleft lip and palate, increased biparietal diameter and decreased abdominal circumference. Cytogenetic analysis (GTG banding) and subsequent fluorescence in situ hybridization (FISH) using whole chromosome paint 1 and multicolor banding (MCB) demonstrated an aberrant karyotype 46,XY,dup(1)(q31q43∼44). The second case was a newborn male infant with multiple congenital malformations. He had a derivative chromosome 18 as a result of a maternal insertion involving chromosomes 1 and 18. Further analyses including MCB showed his karyotype as 46,XY,ins(18;1)(q22;q23q31.1∼32). The present cases and a review of the literature suggest that partial trisomy of the long arm of chromosome 1 is a distinct clinical entity. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

Recovery of gold from various waste materials is mostly achieved through hydrometallurgical methods, which generate a large
amount of secondary chemical waste. Therefore, there is a need to develop an environmentally friendly process for gold recovery.
This paper summarizes research on the recovery of gold ions from chloride solutions using fallen tree leaves. First, leaves
from trees of 16 different species were studied and ranked by the percent of gold that was recovered. Then, several factors—pH,
contact time, shaking rate, and the quantity of ground leaf—affecting the recovery process were studied on leaves from four
selected species. Two kinds of leaves were found to exhibit the efficacy of the most effective sorbents, such as activated
carbon. After recovery, the gold-deposited leaves were heat-treated at 1,200°C to isolate the gold from the leaves. This method
of gold recovery proved to be fast, cheap, and environmentally friendly. 相似文献
