Solid acid catalysts of MgO–Al2O3 mixed oxides containing B4O72−, HPO42−, Mo7O246−, MoO42−, WO42−, and SO42− were synthesized by anion exchange with Cl− located in the space between anionic layers hydrotalcite, followed heat treatment at 773 K. The distance hydroxide was expanded intercalation oxyanions larger than Cl−. interlayer confirmed IR spectroscopy. Acid sites generated on obtained elec...
Aim: Minimal hepatic encephalopathy (MHE) in liver cirrhosis (LC) is a subclinical abnormality which is only detectable by neuropsychiatric and neurophysiological tests. Reliable predictive biomarkers for diagnosing MHE have not been confirmed. This study examined potential biomarkers to detect MHE in LC patients. Methods: We divided 35 outpatients with LC into two groups based on the presence ...
Anaerobic digestion is considered unsuitable for the bioremediation of tannery effluent due to process inhibition, mainly high concentrations sulfur species, and accumulation H2S and/or NH3. This study using standardized biochemical methane potential protocol showed that efficient processing possible with slaughterhouse wastewater, provided sufficient functional biomass present at start SO42? c...
