Gravitational analyses applied to protobind 1000 lignin

Abstract

Lignin derivative (the commercial product -Protobind 1000) offered by the Granit Recherche Developement S.A. company, Lausanne-Schwitzerlandwas synthesized from annual plants. The ligninstands out by a very large range of applications in extremely various domains: agriculture,the pulp and paper industry, constructions or metallurgy.The adsorption-desorption capacity, ion exchange capacity and its catalytic properties are just a few specific characteristics which are emphasizing the importance of harnessing the lignins. Using the gravitational sedimentation, it can be determined in a shorter period of time the particle dimensions comparing with the sieving method, which is a much more complex one.
