Abstrakt: Abstract  Composition and characteristics of lignosulfonic acids recovered from technical-grade ligno-sufonates were studied by IR spectroscopy, viscometry, and elemental and chemical analyses. The dependence of the chemical composition and characteristics of lignosulfonic acids on the procedures of their recovery and purification was examined. [ABSTRACT FROM AUTHOR]
