Cesium and mercury are two mono-valent elements which can be found in toxic industrial, medical, and nuclear wastes. Their presence in the environment has deleterious effects on the ecosystem, living organisms including humans. Due to the chemical nature of these metals, bioremediation by conventional methods is more difficult to achieve compared to other metals. In this study, we used three biosorbents (oak powder, gall nut, and bacterial exopolymer) for the bioremediation of Hg and Cs. Bio-polymer was produced in the GMS mineral broth. Synthetic wastes of Hg(NO3)2 and isotope Cs-133 as the single-metal solutions were used. The biorefining process was carried out in glass columns, made of Pyrex, with dimensions 20?×?7/2?cm2 with a V-shaped bottom. The samples were analyzed using atomic absorption. The experimental results showed that eliminated metal percent by oak powder, gall nut, and bacterial exopolymer were, respectively, of 94.8%, 96%, and 13.8% for Hg and 7.8%, 4.4%, and 69.4% for Cs. The tests revealed that Ca++, when used as flocculant, played a key role in both biosorption and bio-precipitation rates. Consequently, it was concluded that the investigated biosorbents could be use as an integrated biosorption system for the refinement of mixed wastes. 相似文献

Room temperature synthesis of 2H-1,4-benzoxazine derivatives using a recoverable ionic liquid medium

2H-1,4-Benzoxazines are major heterocyclic compounds with interesting biological and synthetic applications. Therefore, it would be very interesting to develop new efficient methods for their synthesis. Here, we synthesized 2H-1,4-benzoxazines in one pot using K2CO3/H2O in the ionic liquid of choice, [omim][BF4]. After reactions, products are extracted from [omim][BF4] by Et2O and the ionic liquid is recovered and successfully reused over several recycles. Results show that high yields of 3-aryl-2H-1,4-benzoxazine derivatives are obtained chemoselectively at room temperature from their corresponding o-aminophenols and phenacyl bromides. To our knowledge, our method represents the most efficient and straightforward route for the synthesis of 3-aryl-2H-1,4-benzoxazine derivatives in short times and under environmentally benign conditions. 相似文献

Effects of Waste Paper Sludge on the Physico-Mechanical Properties of High Density Polyethylene/Wood Flour Composites 总被引:1,自引:0,他引:1
Yahya Hamzeh Alireza Ashori Babak Mirzaei 《Journal of Polymers and the Environment》2011,19(1):120-124
The objective of this work was to determine some physical and mechanical properties of the high density polyethylene (HDPE)
composites reinforced with various mixtures of the paper sludge and the wood flour, and to evaluate the coupling agent performance.
The waste sludge materials originating from two different sources including paper making waste water treatment sludge (PS)
and ink-eliminated sludge (IES) were characterized in terms of physico-chemical properties. In the experiment, four levels
of paper sludge (20, 30, 40 and 60 wt%), three levels of wood flour (20, 40 and 60 wt%), and two levels of coupling agent
(MAPE) content (2 and 3 wt%) were used. The flexural properties of the composites were positively affected by the addition
of the sludge. Especially, tensile modulus improved with the increase of paper sludge content. With the addition of MAPE,
flexural properties improved considerably compared with control specimens (without any coupling agent). The results showed
that the water absorption (WA) and thickness swelling (TS) values of the samples decreased considerably with increasing sludge
content in the composite, while they increased with increasing wood flour content. It is to be noted that with incorporation
of MAPE in the composite formulation, the compatibility between the wood flour and HDPE was enhanced through esterification,
which reduced the WA and TS and improved the mechanical properties. Composites made with IES exhibited superior physico-mechanical
properties compared with the PS filled composites. Overall results suggest that the waste paper sludge materials were capable
of serving as feasible reinforcing fillers for thermoplastic polymer composites. 相似文献
