1. Introduction
A considerable amount of pine cone can be obtained from forested
areas. Pine cones significantly contain cellulose, hemicellulose and
lignin. Also, it contains little amounts of xylose, arabinose and some
extractable compounds. Due to it has a woody structure, pine cones
are evaluated as fuel or fire initiator on a large scale. There is no
important industrial usage of the pine cone. In some researches, it
has been reported that some extraction products obtained from pine
cones can be used as medicine or fungi toxic agent [1].
In a few last decades, a lot of studies on the production of ion exchange
resin from plant residues have been made. Especially, it can
be said that studies mainly focused on the ion exchanger production
from agricultural wastes. The main goals of these studies are to
obtain cheaper and environment-friendly ion exchanging materials.
In fact, most of the commercial ion exchangers are produced from
petroleum derivatives. Some environmental and health risks can occur
during both production and usage of ion exchangers obtained
from petroleum derivatives. For example, although carcinogenic effects
of some petroleum derivatives are well known, ion exchangers
obtained from these derivatives are widely used for drinking water
treatment. So, it can be said that production from the natural sources
is an important issue.
