The waste post-galvanic solutions were applied to obtain valuable products, highly dispersed green pigments. In the studies the post-galvanic nickel wastes were used and, for the comparison, also pure salts of Ni(II), i.e., nickel(II) chloride. A series of nickel(II) silicates and hydrated nickel(II) oxides, which were precipitated from the solutions of sodium metasilicate or sodium hydroxide and the appropriately concentrated waste salts of nickel(II), were obtained. In addition, in the course of such precipitation, non-ionic surfactants, which were supposed to improve the dispersion of the sediments, were introduced to the reaction system. The obtained pigments were subjected to the physicochemical evaluation. The principal parameters were established, including the bulk density, the capacities to absorb water, dibutyl phthalate and paraffin oil. Moreover, the particle size and the particle size distribution were examined in the pigments. For this purpose, the technique of dynamic light scattering was used, taking advantage of the ZetaPlus apparatus.
