METHOD OF OBTAINING SULFIDE OF CADMIUM WITH USE OF SULFATE-REDUCING BACTERIA

摘要

A method of preparing crystalline cadmium sulfide by placing the sulfate-reducing bacteria in a synthetic medium containing metals, with the addition of nutrients, including vitamins solutions, salts, cofactors, characterized in that when cultured using sulphate-reducing bacteria Desulfovibrio sp. A2, using a synthetic medium containing a source of the cadmium ions - cadmium chloride solution, the concentration of cadmium ions in synthetic media 150 mg / L, with a container for the cultivation was placed an aluminum foil, the cultivation is carried out at a temperature of 28 ° C for 18 days, and assembled with the foil and the bottom of the vial precipitate containing cadmium sulfide crystals dried.
