| Popis: | We have investigated the possibility of differential determination of Zn2+, Co2+ and Cu2+ in model aqueous media in a system with the cultures of bacteria Pseudomonas sp. B4251, Bacillus cereus B4368, E. coli 1257. We have developed and created a multibiosensor based on capacity structures of the type electrolyte-dielectric-semiconductor and an ion sensitive layer of silicon nitride. The lower boundary of the method sensitivity constituted: for zinc—0.2, for cobalt—0.05, for copper—0.1 mg/dm3, which corresponds to 1–3 M in terms of metal. |
