ABSTRACT
The pK spectroscopic method is an advanced method to examine the balance in complex naturalistic systems that lack data on their functional structure and are difficult to be studied with classical methods that sometimes fail to provide sufficient information on their structure. Mathematical justification of the method pK spectroscopy is described in Ryazanov [1]. Previously, this method has been successfully applied to study various homogeneous and heterogeneous systems listed in the work given in Ref. [2]. To examine the suspensions of such composition of biopolymers as lignocellulosic material, the present method was used for the first time. This study by means of the use of the pK spectroscopy method shows the difference between the acid-base properties of the suspensions of unbleached softwood cellulose and the products of its destruction obtained by different methods.
