Labdane-type diterpenoids from Juniperus communis needles
(2015-12-15)
Article
Accés obertThe chemical composition of lipophilic extractives from Juniperus communis used for cosmetic, medicinaland food additives was studied. Herein we report the extraction of labdane-type diterpenoids from theneedles of the ... -
Biofiltration of WWTP sludge composting emissions at contact times of 2–10 s by structured/unstructured packing materials
(2015-05-29)
Article
Accés obertThe performance of a biotrickling filter for the abatement of composting emissions was evaluated at short gas contact times of 2–10 s with a structured and an unstructured packing material. The effect of the gas contact ... -
Application of a novel respirometric methodology to characterize mass transfer and activity of H2S-oxidizing biofilms in biotrickling filter beds
(2015-07-15)
Article
Accés obertThe elimination capacity of gaseous H2S biofiltration can be limited either by mass transfer or bioreaction in the biofilm. Assessment of the biological activity of immobilized cells (biofilm) usually implies morphological ... -
Profiling of oxygen in biofilms using individually addressable disk microelectrodes on a microfabricated needle
(2015-04-01)
Article
Accés obertA novel microelectrode array sensor was fabricated using MEMS technology on a needle, and then applied to real-time measurement of dissolved oxygen (DO) inside biofilms. The sensor consists of eleven gold disk microelectrodes ... -
Role of activated carbon properties in atrazine and paracetamol adsorption equilibrium and kinetics
(2015-05-20)
Article
Accés obertAdsorption of two widespread emerging water contaminants (atrazine and paracetamol) onto three different activated carbons was investigated. The carbons were characterized and the influence of their physicochemical properties ... -
Kinetic and stoichiometric characterization of anoxic sulfide oxidation by SO-NR mixed cultures from anoxic biotrickling filters
(2015-01-01)
Article
Accés obertMonitoring the biological activity in biotrickling filters is difficult since it implies estimating biomass concentration and its growth yield, which can hardly be measured in immobilized biomass systems. In this study, ... -
Kinetics of sorption of polyaromatic hydrocarbons onto granular activated carbon and Macronet hyper-cross-linked polymers (MN200)
(2007-06-01)
Article
Accés restringit per política de l'editorialPolymeric supports are presented as an alternative to granular activated carbon (GAC) for organic contaminant removal from groundwater using permeable reactive barriers (PRB). The search for suitable polymeric sorbents for ... -
Resorcinol and m-guaiacol alkylated derivatives and asymmetrical secondary alcohols in the leaves from Tamarix canariensis
(2014-12)
Article
Accés obertIn the study of leaves from the halotolerant saltcedar (Tamarix canariensis Willd.) we have found a new abundant source of resorcinolic as well as guaiacolic compounds. A homologous series of 5-n-alkylresorcinols with long ...
