According to the findings chitosanglucan complex sorbs lead and copper ions (130–140 mg/g) better than chitin-glucan complex (50–80 ex mg/g). Langmuir theoretical model with R2= 0,996 determination coefficient well describe sorption isotherms. It is shown the chelate complex formation compound character based on ion and coordination bonds by chitin and chitosan biopolymers is more complex. According to test results the production of chitin and chitosan containing biopolymers from citric acid production mycelium by-products has a good future.  The above biopolymers have a functional use. Besides of that they sorbs heavy metals and radionuclide ions.</p></abstract><trans-abstract xml:lang="ru"><p>Цель работы заключается в изучении сорбционной способности хитин и хитозансодержащих ингредиентов, выделенных из мицелия гриба Aspergillus niger. Установлено, что сорбционная емкость хитозанглюканового комплекса по отношению к ионам свинца и меди (130–140 мг/г) значительно выше, чем у хитинглюканового комплекса (50–80 мг/г). Изотермы сорбции хорошо описываются теоретической моделью Лэнгмюра с коэффициентом детерминации R2= 0,996. показано, что механизм сорбции на хитин- и хитозановых биополимерах имеет сложный характер образования хелатных комплексных соединений на основе ионной и координационной связей. Результаты исследований свидетельствуют о перспективности получения из мицелиальных отходов производства лимонной кислоты хитин- и хитозансодержащих биополимеров функционального назначения, сорбционноактивных по отношению к ионам тяжелых металлов и радионуклидам.</p><p> </p></trans-abstract><kwd-group xml:lang="ru"><kwd>мицелий</kwd><kwd>Aspergillus niger</kwd><kwd>хитин  и хитозан</kwd><kwd>изотермы сорбции  меди</kwd><kwd>свинца</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mycelium</kwd><kwd>Aspergillus niger</kwd><kwd>chitin  and chitosan</kwd><kwd>cuprum and lead  sorption isotherms</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Скрябин, К.Г., Вихорева, Г.А.,.
