URBINA, R.; CASANOVA, J.; PEREZ, N.  e  FERNANDEZ, J.. Evaluation of the adsorptive quality for Ni and v of kraft lignin under different conditions. Lat. Am. appl. res. [online]. 2009, vol.39, n.4, pp.361-365. ISSN 0327-0793.

In this study, the impact of the precipitation process over the adsorption capability of Nickel and Vanadium of precipitated lignins of Kraft black liquor was studied. The studied conditions of precipitation were: mixing (shaking and stirring), mixing speed and mixing sequence. To determine the best lay out for the studied conditions, the quantity of produced adsorbent by precipitation and its adsorption capability were correlated. It was determined that the type of mixing in the process of precipitation affects the adsorption capability of lignins and conditions for a higher adsorption capability of each of the studied metals were determined.
