A method for sorption capacity determination of cellulose
matrices as trace metal sorbents has been studied. An analytical
method is based on infrared absorption band at 1725 cm-• featuring
C=O streching in a polymer molecule. Suitable samples are prepared
to construct a calibration curve. Samples are standardized
by the potentiometric method in terms of ion-exchange capacity.
Some features of the analytical procedure are discussed, particularly
with regard to the lower and upper limit of COOR-content
determination, the influence of sample structure and the precision
of the proposed method
