摘要

ufeffsyntu00e9za nanokompozitu consisting of four steps: first, with the uniform dispersion dispergacu00ed creates ligninsulfonovu00e9 acid in water, followed by the stage of the complex ligninsulfonovu00e9 acid with iron ions fe.sup.3 +.n.a / or fe.sup.2 +.n.in acidified aqueous solution, especially using a mineral acid, precipitation of iron oxide nanokompozitu - lsa method co precipitation using hydrolyzau010dnu00edho reagent such as sodium hydroxide, ammonium hydroxide, potassium hydroxide or tetraetylamonium hydroxide and the formation of particles of carbon iron, a black ink clots,this precipitate is then washed with distilled water until the ph of the filtrate to achieve ~ 7 and dried into a powder.
