Methodology of determination of free cyanide (CN-) in industrial wastewaters
Kaplan, Ondřej; Chmátal, Martin; Veselá, Alicja Barbara; Rinágelová, Anna; Martínková, Ludmila
2015 - Czech
This work summarizes the current state in the methodology of CN- determination particularly in industrial wastewaters. It also describes in detail the determination of cyanide ions after their enzymatic conversion into formamide, which is determined by HPLC (including the method of preparation of the enzyme). Práce shrnuje aktuální metodiky stanovení CN- zejména v průmyslových odpadních vodách. Je zde dále podrobně popsán způsob stanovení kyanidových iontů po jejich enzymové konverzi na formamid, který se stanoví pomocí HPLC.

BIOGENIC AND SYNTHETIC AMORPHOUS SILICA - COMPARE AND INTERACTION WITH BACTERIAL SYSTEMS
Fijalkowski, M.; Adach, K.; Marešová, Helena; Kroisová, D.
2015 - English
The aim of the work is to compare the biogenic silica nanoparticles, which have been isolated from rice husks with synthetically produced silica brand Cab-O-Sil LM-150. The comparison is based on an evaluation of the two systems from the point of view of chemical composition, particle size and structure, ability to form clusters of particles and interactions with selected bacterial systems. Methods used for comparison were: SEM, EDX, TEM, FTIR, ICPOES and bacteriological tests. Husks are standardly contaminated by accompanying ions that are important for plant growth, but undesirable for obtaining a quality product. Rice husk used for the silica isolation were purified by boiling in 10% HCl for 2 hours. Rice husks were then washed with distilled water until pH 7. The dried and purified husks were burned in an oven at 650 degrees C of ramping temperature 10 degrees C/min during 2 hours. The obtained product has a chemical composition analogous to the synthetic product. Biogenic particles reach a size of about 20 nm, about 10 nm synthetic. Both materials have an amorphous structure. Interaction with bacterial systems was performed with Gram-negative bacteria Escherichia coli W3110 strain and Gram-positive bacteria Bacillus cereus. In both cases analogous behaviour was observed depending on the concentration of nanoparticles and reducing the growth rate of cultures of 8% for E. coli and 5% for B. cereus resulted nanoparticles at the concentration of 150 mg/litter of medium.
