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
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

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
Sorption of lead, copper, and cadmium by calcium alginate. Metal binding stoichiometry and the pH effectSpringer Science and Business Media LLC - Tập 19 - Trang 3516-3524 - 2012
Wojciech Plazinski
Binding of heavy metal ions by calcium alginate has been described in the literature with many different models. In the present study, two most basic models were used to systematically compare their simultaneous description of metal uptake dependence on pH and metal ion concentration in the bulk solution. The experimental datasets corresponding to the binary sorption systems containing protons and...... hiện toàn bộ
Scents in the stack: olfactometric proficiency testing with an emission simulation apparatusSpringer Science and Business Media LLC - Tập 25 - Trang 24787-24797 - 2018
Stephan Stöckel, Jens Cordes, Benno Stoffels, Dominik Wildanger
Olfactometry is globally acknowledged as a technique to determine odor concentrations, which are used to characterize odors for regulatory purposes, e.g., to protect the general public against harmful effects of air pollution. Although the determination procedure for odor concentrations is standardized in some countries, continued research is required to understand uncertainties of odor monitoring...... hiện toàn bộ
