This invention belongs to the field of inorganic material preparation and relates to a method for preparing flower-shaped basic
copper nitrate. The method is characterized by: (1) preparing a
copper nitrate solution with a concentration of 0.1-0.6 mol / L; (2) using
triethanolamine as the only amine morphology
regulator and complexing agent at a speed of 200-500 rpm, adding
triethanolamine with an initial concentration of 0.2-0.4 mol / L to the
copper nitrate solution, stirring the reaction at 30-70℃ for 0.5-3.0 h, and controlling the pH of the
mixed solution between 4.0 and 7.0; (3) after the reaction, the precipitate is not aged and allowed to stand, and is directly washed by
centrifugation with deionized water and
ethanol more than three times, and dried to obtain flower-shaped basic
copper nitrate. The beneficial effects of this invention are: a basic
copper nitrate with good dispersibility, regular shape and good stability is prepared by a one-step
precipitation method. It has the advantages of simple synthesis steps, mild
reaction conditions and green
environmental protection, and is suitable for industrial production.
