Not Accessible

Your library or personal account may give you access

Abstract

At the level of the requirements of refractometric technologies, this paper presents the results of measurements of the refractive index, its concentration and temperature dependences, and also the UV absorption in green liquors formed in the production of sulfate cellulose. The design features and technical–operational parameters of a commercial refractometer for monitoring the overall alkalinity of green liquors are briefly considered.
