Kraft black liquor, analysis

Analysis of small ions has been published for many applications other than pharmaceutical applications, and has a growing impact in industrial, environmental, biomedical, clinical, and forensic laboratories. Sample matrices range from simple tap water to Kraft black liquor, including river and seawater, beer and wine, environmental water, and nuclear plant water, but also body fluids such as serum, urine, plasma, cerebrospinal fluid, and many others. Those topics alone would require a separate book. 

The kraft black liquor, employed in the experiments, originated from a laboratory cook of Scots pine (Pinus sylvestris). An analysis of the liquor is given in Table I.

NMR analysis of black liquor lignins indicated increases in the ratio of substituted to unsubstituted aromatic carbons, suggesting that lignin from these bio-pretreatments may be more condensed than that obtained from a normal kraft pulp.
