METHOD OF PREPARING BIOSORBENTS

摘要

FIELD: biotechnology. SUBSTANCE: biosorbents with polyampholyte properties, which may be used for removing from solutions radionuclides and heavy metal ions both in cathionic and anionic form, are prepared by preliminarily heat treating biomass to 5-30% loss in dry substance weight followed by treatment with 0.1-1.25 N alkali solution until coloring of solution is disappeared. EFFECT: improved process.
