Progress during this quarter is described on four tasks. The first task involves the recovery of organic matter from bleach effluents and black liquors, separation of carbohydrates and lignin degradation products, analysis of functional groups, and characterization of carbohydrate polymers. Progress in the second task was made in the selection of model compounds. Several subtasks are complete in Task 3, but the paper summarizes progress made in the determination of the residual hemicellulose content in the pulp samples. Finally, results are given for the measurement of metal adsorption isotherms on wood pulp. Goals for the next quarter are listed
