Адсорбция органических и неорганических ионов на железоуглеродных композиционных материалах

Abstract

It was ascertained that composite iron-carbon nanoparticles have negative surface charge, zeta-potential value amounts is -71mV. It was shown by the example of doxorubicin and coloring agents(methyl blue, eosin) that nanoparticles sorb efficiently the organic substances being in solutions in cationic form. And in this article also investigate the process of selective extraction of non-organic ions from water solutions by iron-carbon sorbent. Sorption isotherms of Ni{2+}, Cr[2]O[7]{2}- and H[2]AsO[4] --ions were obtained which were well approximately using Langmuir equation. As a result the conclusions were made possibility of application iron-carbon sorbent in process of water treatment and in quality of magnetic carrier of carrying doxorubicin to cancer cells.
