Abstract

Abstract: The adsorption properties of chitin adsorbent from mycelium of fermentation industries for
the removal of heavy metal ions werestudied. The result shows that the chitin adsorbent has
high adsorption capacity for many heavy metal ions and Ni2+ in citric acid. The influenceof
pH was significant: When pH is higher than 4.0, the high adsorption capacity is obtained,
otherwise H+ ion inhibits the adsorption of heavymetal ions. The comparison of the chitin
adsorbent with some other commercial adsorbents was made, in which that the adsorption
behavior ofchitin adsorbent is close to that of commercial cation exchange adsorbents, and
its cost is much lower than those commercial adsorbents.

Key words: mycelium chitin, adsorbents, heavy metal ions
