Producing adsorbents from nitrated asphaltites

  • Yu. V. Pokonova
Article

Carbon adsorbents with mechanical strengths of 90-93% and a micropore volume of 0.16-0.3 cm3/cm3 have been obtained from nitrated asphaltites by the existing industrial technology. Compared to industrial carbon with the trademark KAD-iodine, medium-charred specimens are highly selective in extracting gold and silver from multicomponent polymetal solutions and have a high capacity for sorbing arsenic from waste waters.

Key words

finely porous carbon adsorbents adsorbents for selective extraction of noble metals nitrated asphaltites
