FIELD: chemistry. ^ SUBSTANCE: invention relates to producing the fibers of the oxide-hydroxide phases with aluminum metahydroxide structure and can be used in producing the adsorbents for purification the drinking water, industrial and waste waters. Production of the nanofibers of the oxide-hydroxide aluminum phases is performed by hydrolysis of the powder obtained in electric exposure of the aluminium wire with diameter 0.3<d<=0.4 mm in the nitrogen atmosphere under pressure P<3 atmospheres and energy 19.8 J/mm3<E<=66 J/mm3, applied to the wire. At that, the following powder hydrolysis is performed at temperature not more than 70°C. The obtained nanofibers of the oxide-hydroxide aluminium phases have the length 0.1-0.2 mcm, diameter 0.001-0.013 mcm and the specific surface up to 500 m2/g. ^ EFFECT: allows to increase production output together with decrease of energy consumption. ^ 5 cl, 2 dwg, 3 ex |
