Analysis of Bleach Liquors,y complex mixture of substances varying in chemical structure and molecular weight. The interest has particularly been focused on methods for monitoring the formation and discharge of chlorinated organic matter. Methods for determination of both sum parameters and specific compounds have been developed for this purpose.

Ettore Majorana International Science Series of the wood sample before analysis can lead to unreliable results because of contamination with tissues not typical of the expected normal wood. Guidelines for the selection of wood material are given in the first part of this chapter. The discussion is limited to stem wood.

Dynamical Processes in Disordered Systems, formed of about 100 cellulose chains, are embedded in a matrix of hemicelluloses and lignin. Pores in the matrix are small and enable transfer of water, salts, and small organic molecules only. Although the hemicelluloses are at least partly water soluble, they cannot diffuse out of the cell wall due to their molecular size.
