The invention discloses a method for preparing rod - shaped manganese metavanadate powder. solution, slowly drop this solution into the MnSO solution, continuously magnetically stir during the addition, continue stirring for 8-15 minutes after obtaining the brown precipitate, move it into a polytetrafluoroethylene-lined autoclave for heating and react, and cool it Then, after washing and drying, a rod-shaped Mn(VO 3 ) 2 sample was obtained. The invention can prepare rod-shaped manganese metavanadate with uniform morphology without adding surfactant, and use K 2 (H 2 O) 10 H 2 V 10 O 28 ยท4H 2 O as vanadium source, In addition, the preparation process is simple, the cycle is short, the production process is safe, and the production efficiency is high, and the prepared rod-shaped manganese metavanadate can better degrade organic dyes such as methylene blue and rhodamine B under ultraviolet light. |
