Advanced adsorbents for ibuprofen removal from aquatic environments: a review
Springer Science and Business Media LLC - - Trang 1-46 - 2023
Ahmed I. Osman, Ali Ayati, Mohamed Farghali, Pavel Krivoshapkin, Bahareh Tanhaei, Hassan Karimi-Maleh, Elena Krivoshapkina, Parsana Taheri, Chantal Tracey, Ahmed Al-Fatesh, Ikko Ihara, David W. Rooney, Mika Sillanpaä
The presence of pharmaceuticals in ecosystems is a major health issue, calling for advanced methods to clean wastewater before effluents reach rivers. Here, we review advanced adsorption methods to remove ibuprofen, with a focus on ibuprofen occurrence and toxicity, adsorbents, kinetics, and adsorption isotherms. Adsorbents include carbon- and silica-based materials, metal–organic frameworks, clay...... hiện toàn bộ
Predicting the transportation tendency and potential reservoirs of dioxins by compartment distribution coefficient
Springer Science and Business Media LLC - Tập 9 - Trang 267-271 - 2010
Yuying Dong, Zening Zheng, Yingli Zhao, Xianliang Qiao, Xuehua Li
We assessed the transportation tendency of dioxins and predict locations at high risk for dioxin pollution. A new parameter, the compartment distribution coefficient DC, was created to account for the tendency of dioxins to preferentially accumulate in particular compartments. It was obtained by a model using levels of polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs) in four countries: Ja...... hiện toàn bộ
Gas-phase degradation of CCl4, CHCl3 and CH2Cl2 over metallic Fe
Springer Science and Business Media LLC - Tập 2 - Trang 9-13 - 2004
Sergei Preis, Juha Kallas
We studied the hydrolysis of gas-phase carbon tetrachloride (CCl4), chloroform (CHCl3), and dichloromethane (CH2Cl2) over a metallic Fe surface for its application in combination with air stripping and soil vapour extraction. The effects of chlorocarbon concentration, type and preparation of the iron-containing material, humidity, and temperature on process performance are reported. The hydrolysis...... hiện toàn bộ
Recent developments on gas–solid heterogeneous oxidation removal of elemental mercury from flue gas
Springer Science and Business Media LLC - Tập 17 - Trang 19-47 - 2018
Wei Yang, Yusuf G. Adewuyi, Arshad Hussain, Yangxian Liu
Mercury is a toxic and persistent environmental pollutant which has been recognized as a global threat to human health and our ecosystem because mercury bio-accumulates in the food chain and can be transformed into the more neurotoxic methylmercury. Among current and emerging abatement technologies for elemental mercury in flue gas, gas–solid heterogeneous oxidation is nowadays gaining increasing ...... hiện toàn bộ
Insecticidal activity of metallic nanopesticides synthesized from natural resources: A review
Springer Science and Business Media LLC - Tập 21 - Trang 1141-1176 - 2022
Chengxi Li, Yapeng Han, Tiantian Gao, Jun Zhang, De-Xiang Xu, Yán Wāng
Insects are a major source of human diseases and agricultural loss, but actual insecticides are highly toxic for humans, thus calling for advanced pesticides. For instance, metallic nanoparticles have recetly attracted research attention as pesticides, because metallic nanoparticles can be synthesized from natural resources by green methods. Here we review metal-based nanoparticles as insecticides...... hiện toàn bộ
Supported single-atom catalysts: synthesis, characterization, properties, and applications
Springer Science and Business Media LLC - Tập 16 - Trang 477-505 - 2017
Jing Liu, Benjamin R. Bunes, Ling Zang, Chuanyi Wang
In recent years, there has been a wide research in supported single-atom catalysts (SACs), which contain only isolated individual metal atoms dispersed on an appropriate support or coordinated with the surface atoms of the support. The SACs exhibit many fascinating characteristics including high activity, selectivity, and maximum atomic utilization. These characteristics arise from the low coordin...... hiện toàn bộ
High immobilization of soil cesium using ball milling with nano-metallic Ca/CaO/NaH2PO4: implications for the remediation of radioactive soils
Springer Science and Business Media LLC - Tập 10 - Trang 201-207 - 2012
Srinivasa Reddy Mallampati, Yoshiharu Mitoma, Tetsuji Okuda, Shogo Sakita, Mitsunori Kakeda
This report shows that cesium can be immobilized in soils with an efficiency of 96.4% by ball milling with nano-metallic Ca/PO4. In Japan, the major concern on 137Cs deposition and soil contamination due to the emission from the Fukushima Daiichi nuclear power plant showed up after a massive quake on March 11, 2011. The accident rated 7, the highest possible on the international nuclear event scal...... hiện toàn bộ
Removal of malachite green from water samples by cloud point extraction using Triton X-100 as non-ionic surfactant
Springer Science and Business Media LLC - Tập 8 - Trang 53-57 - 2008
Nahid Pourreza, Sh. Elhami
A surfactant mediated cloud point extraction (CPE) procedure has been developed to remove color from wastewater containing malachite green using Triton X-100 as non-ionic surfactant. The effects of the concentration of the surfactant, temperature and salt concentration on the different concentrations of dye have been studied and optimum conditions were obtained for the removal of malachite green. ...... hiện toàn bộ
Nanocarriers for drug delivery applications
Springer Science and Business Media LLC - Tập 17 - Trang 849-865 - 2018
Munusamy Chamundeeswari, John Jeslin, Madan Lal Verma
Nanobiotechnology research has recently provided numerous basic and applied advances in the health sector. Nanocarriers have been developed for efficient drug delivery and diagnostic tools. Nanocarrier enables an effective, targeted biomolecular interaction in order to lower side effects caused during the treatment. Here, we review the problems associated with the conventional drug development and...... hiện toàn bộ
