The fate of phosphorus concerning its distribution in the thermal process and chemical speciation was studied during co-combustion sewage sludge with wheat straw sunflower husks powder combustion conditions. Co-combustion experiments were performed a lab-scale entrained flow reactor (EFR) at 1000 °C 1400 °C. SEM-EDS ICP-OES analyses used for studies deposits collected on probe, bottom ash, part...

B. megatherium phage, like staphylococcus phage, is inactivated by repeated high speed centrifugation (Northrop, 1938; Hotchin, 1954). This method of purification has the additional disadvantage that large volumes of material cannot be handled. B. megatkerium phage is precipitated from peptone solution by 0.4 saturated ammonium sulfate. The precipitate is filtered off, washed, and dissolved in ...

INTRODUCTION The purpose of this in vitro study was to determine whether para-chloroaniline (PCA) is formed through the reaction of mixing sodium hypochlorite (NaOCl) and chlorhexidine (CHX). METHODS Initially, commercially available samples of chlorhexidine acetate (CHXa) and PCA were analyzed with 1H nuclear magnetic resonance (NMR) spectroscopy. Two solutions, NaOCl and CHXa, were warmed t...

The production of a precipitate by Serratia marcescens on Oxoid MacConkey agar has proven useful as a laboratory diagnostic test. This phenomenon is specific for Serratia within the Enterobacteriaceae, although precipitate production is also given by Acinetobacter anitratus and some Pseudomonas, Alcaligenes, and Aeromonas species. Precipitate production seems to be specific for certain batches ...

The separation of inorganic precipitates with similar solubility products is a challenging task in chemical engineering. We present computational fluid dynamics study precipitation reaction flow-driven reactor. For reference study, the cobalt(II)-copper(II)-oxalate system selected, where occurs simultaneously and difference within an order magnitude as shown experimentally. general description ...
