| Abstract: | It was established in the experiments determining the influence of the mushroom powder on acidity of the HCl solution by means of ionometrical method that in 15 minutes after introduction 3 gram of the powder pH of the solution increases from 1.62 up to 2.64. The stable meaning of the solution pH (without fall) can be (held) the same in the presence of the powder more than 23 hours. The mushroom powder reduces the high content of the ions Pb2+ and Cu2+ in the solution from 8.8 x 10(-6) up to 3.3 x 10(-6) and from 11.8 x 10(-6) up to 8.6 x 10(-6) mole/ml correspondingly. The trustworthy reduction (fall) of the concentration of the ions Zn2+ and Cd2+ in the filtrate was not discovered (found out). To determine the content of metal in the solution the method of flaming atomic adsorption. |
