SORPTION PURIFICATION OF WATER FROM HEAVY METAL IONS USING SULFOUGL

The sorption capacity of modified activated carbon is investigated; the possibility creating a sorbent for iron (II, III) in water bodies with purified yield up to 0.01 mg/l shown. A sulfogroup was used as modifier and complexing agent. To date, thousands sorbents are produced various matrix materials, functional groupings, ways fixing them, containers, mechanical properties, granulation other characteristics. choice optimal depends on task assigned researcher. large extent, determined by nature micro–component - form existence this component solution, size charge an ion or molecule, ability react groups directly surface sorbent. When choosing sorbent, it necessary take into account concentration mode. Thus, after extraction under static conditions, concentrate should be easily separated from mother liquor; when dynamic mode, undesirable use strongly swelling sorbents, well too small fractions sorbents. In combined techniques, where first step concentration, second quality control water, spectroscopic methods such spectrophotometry, atomic absorption spectroscopy (AAS), emission inductively coupled plasma (NPP-ISP), mass spectrometry (MS-ISP) can act, rapid quantitative elution elements. development express simple purification heavy metals, particular, widespread cation natural drinking waters important analytical chemistry. This due high prevalence environmental objects biomedical effect excess its ions human body.
