Preparation of ionic liquid modified graphene composites and their adsorption mechanism of arsenic (V) in aqueous solutionSpringer Science and Business Media LLC - - Trang 1-12 - 2024
Yingli Li, Keyi Xiang, Guangfei Qu, Rui Li
Graphene (GR) is a new type of carbon-based material that combines many excellent properties. In order to give full play to the excellent properties of graphene and expand its application scope, this study used ionic liquid SbF6 to modify it and successfully prepared ionic liquid modified graphene composites (H/GR), and studied its adsorption mechanism of arsenic in aqueous solution.

Although bottom ash (BA) [or mixtures of bottom and fly ash (FA)] from clean biomass fuels is currently used as liming agent, additive for compost, and fertilizer on agricultural and forest soils in certain European countries, in several other countries most of the ashes are currently disposed in landfills. This is due to both a lack of a proper classification of the materials and of regulatory ba...... hiện toàn bộ
Hydrochemistry dynamics in remote mountain lakes and its relation to catchment and atmospheric features: the case study of Sabocos Tarn, PyreneesSpringer Science and Business Media LLC - Tập 22 - Trang 231-247 - 2014
Zoe Santolaria, Tomas Arruebo, José Santiago Urieta, Francisco Javier Lanaja, Alfonso Pardo, José Matesanz, Carlos Rodriguez-Casals
Increasing the understanding of high mountain lake dynamics is essential to use these remote aquatic ecosystems as proxies of global environmental changes. With this aim, at Sabocos, a Pyrenean cirque glacial lake or tarn, this study shows the main results of a morphological and catchment characterization, along with statistical analyses of its hydrochemical trends and their concomitant driving fa...... hiện toàn bộ
Effects of multiple antibiotics on greenhouse gas and ammonia emissions during swine manure compostingSpringer Science and Business Media LLC - Tập 27 - Trang 7289-7298 - 2019
Zhiqiang Chen, Yiqi Wu, Qinxue Wen, Hongwei Ni, Chunrong Chai
Antibiotics are commonly used in intensive farming, leading to multiple antibiotic residue in livestock waste. However, the effects of multiple antibiotics on the emissions of greenhouse gas and ammonia remain indistinct. This paper selects sulfamethoxazole and norfloxacin to represent two different types of antibiotics to explore their effects on gaseous emissions. Four treatments including CK (c...... hiện toàn bộ
Facile synthesis of ZnO-SnO2 anchored ZIF-8 nanocomposite: a potential photocatalystSpringer Science and Business Media LLC - Tập 27 - Trang 25103-25118 - 2020
Ramesh Chandra, Mala Nath
For the first time, ZnO-SnO2 nanocomposite has been anchored (ZS@Z) on ZIF-8 (zeolitic imidazolate framework) surface and encapsulated (ZS@Z1, ZS@Z2 and ZS@Z3) within ZIF-8 matrix during the in situ synthesis of ZIF-8. ZnO-SnO2 nanocomposites were synthesized in various molar ratio of Zn and Sn, i.e. 1:1, 2:8, 4:6, 6:4 and 8:2 (abbreviated as ZS-11, ZS-28, ZS-46, ZS-64 and ZS-82) using sol-gel and...... hiện toàn bộ
Monitoring OH-PCBs in PCB transport worker’s urine as a non-invasive exposure assessment toolSpringer Science and Business Media LLC - Tập 25 - Trang 16446-16454 - 2018
Yuki Haga, Motoharu Suzuki, Chisato Matsumura, Toshihiro Okuno, Masahiro Tsurukawa, Kazuo Fujimori, Narayanan Kannan, Roland Weber, Takeshi Nakano
In this study, we analyzed hydroxylated polychlorinated biphenyls (OH-PCBs) in urine of both PCB transport workers and PCB researchers. A method to monitor OH-PCB in urine was developed. Urine was solid-phase extracted with 0.1% ammonia/ methanol (v/v) and glucuronic acid/sulfate conjugates and then decomposed using β-glucuronidase/arylsulfatase. After alkaline digestion/derivatization, the concen...... hiện toàn bộ
