METHOD FOR TREATING LIQUID CONTAINING MERCURY IONS AND MERCURY ION ADSORBENT

摘要

Provided is a method for treating a liquid containing mercury ions by means of which mercury ions are inexpensively and selectively adsorbed, and also provided is a mercury ion adsorbent. The method for treating a liquid containing mercury ions and the mercury ion adsorbent according to the present invention use a granular adsorbent which comprises a granular substrate to which has been introduced a graft chain produced by polymerization using a monomer containing (meth)acrylic acid dialkylaminoalkyl. Therefore, mercury ions can be inexpensively and selectively adsorbed.
