The results of studies of interaction in aqueous solutions polihexamethyleneguanidine hydrochloride (PHMG GC) with metallic ions Zn (II), Cu (II), Pb (II), Cd (II). Methods of mercury electrode polarography found that recovery Pb (II), Cd (II) in the presence PHMG is no significant change at half-wave potential , but the diffusion current significantly reducing. This indicates recovery akvakompleksiv Pb (II) and Cd (II) to form insoluble associates with PHMG. Recovery of Zn (II) and Cu (II) happens with a shift in the half-wave potential negative area and with a reduction of the limit diffusion current, indicating the formation of soluble associates for donor-acceptor mechanism. The method of infrared spectroscopy revealed that the formation PHMG-Me (II) is -asotsiativ involving huanydinovoyi group, as evidenced by a shift frequencies in the infrared spectrum. Polihexamethyleneguanidine dosed in aqueous solution at its purification by precipitation as hydroxides 1,5 ? 2 times increases the speed and reduces their fidtruvannya from 92% to 68% vodoyemnist precipitable hydroxides. It was shown that composite materials teploakkumulyuyuchi natural zeolite-MgSO4 schylnist teploakkumulyuvannya increases to 130 kWh / m3. Product Description popup.authors Семікіна О.В.
