Abstract—The structure of hydrolysis lignin oxidized with hydrogen peroxide in acid medium was studied by
NMR spectroscopy and by matrix-assisted laser desorption/ionization and electrospray ionization mass spec-
trometry. The sorption, ion-exchange, and surfactant properties of oxidized hydrolysis lignin were studied, and
possible application areas of this substance were suggested.
Oxidation of hydrolysis lignin (HL) with hydrogen
peroxide in acid medium was studied previously . The
lignin product obtained under these conditions is soluble
in dilute alkali.
In this work, we studied the chemical structure and
physicochemical properties of oxidized hydrolysis lignin.
Experiments were performed with hydrolysis lignin
from Bobruisk Hydrolysis Plant (Belarus), recovered
from softwood. The oxidation procedure and methods
for analysis of hydrolysis lignin and oxidized hydrolysis
lignin (OHL) are described in detail in . The analytical
characteristics of the initial and oxidized hydrolysis lignin
are given in Table 1.
The OHL yield was 75.1%. Thus, the HL oxidation with
hydrogen peroxide in acid medium yields approximately
25% low-molecular-mass compounds soluble in the
The sorption properties of OHL were determined
by the procedure accepted for evaluating the sorption
properties of enterosorbents .
The ion-exchange properties of OHL were determined
as follows. A 250-mL ﬂ ask was charged with 0.1 g of
OHL and 80 mL of Н
О, and the contents were stirred for
5 min on a magnetic stirrer. After that, 20 mL of a 0.01 M
solution was added, the mixture was stirred for
