- Abstract
- Process of modification sunflower seed hull for the purpose of reception of adsorbent for removal of ions of chrome (VI) of modelling solutions of sewage is investigated. It is shown that the yielded process depends on the chemical nature and concentration of modifying material, temperature and duration of carrying out of process of modification. It is considered adsorbent from sunflower seed hull, by the modified 2,5 M solution of sulfuric acid at temperature 60 оС within 30 minutes. It is proved that such adsorbent is preferable for using to removal from water solutions of ions of chrome (VI) as it has higher sorption characteristics, than not modified sunflower seed hull.
