Abstract	The influence of AlCl3 (0–10−3 M) and pH (9.5–2.0) on the aggregation of dilute (10 mg/l) aqueous dispersions of kraft lignin is studied by filtration through several track membranes with pore diameters of 50–2500 nm. AlCl3 is shown to have markedly higher coagulating ability than NaCl and CaCl2. In a pH range of 4.1–7.0, which corresponds to the significant hydrolysis of AlCl3, the concentration inversion of AlCl3 coagulating ability is observed when passing from 10−4 to 10−3 M, which is caused by the charge reversal of negatively charged kraft lignin particles under the action of AlCl3 hydrolysis products.
