Abstract

Abstract

In response to the issues of lengthy process and high cost associated with traditional ammonium metavanadate preparation methods, this study proposes an innovative approach based on the pH-dependent speciation transformation characteristics of vanadate ions. By precisely controlling the pH of the medium, direct conversion of decavanadate (V₁₀O₂₈⁶⁻) to metavanadate (VO₃⁻) was achieved. During this process, impurity elements (Na, K, Cr, As) were effectively removed through their transformation into ionic forms (Na⁺, K⁺, CrO₄²⁻, HAsO₄²⁻) in the solution phase, enabling simultaneous impurity control in ammonium metavanadate preparation. The effects of transformation temperature, pH, and liquid-to-solid ratio on vanadium recovery and product purity were systematically investigated. Experimental results demonstrated that complete conversion of V₁₀O₂₈⁶⁻ to VO₃⁻ could be achieved at pH monstrated that complete conversiwere found to favor the crystallization of ammonium metavanadate, thereby enhancing vanadium recovery. While increasing the liquid-to-solid ratio improved conversion efficiency, excessive ratios led to reduced vanadium recovery and resource wastage. Through optimization experiments, the optimal process parameters were set: reaction temperature of 30 ℃, pH of 8.5, and liquid-to-solid ratio of 7–10. Under these conditions, industrial-grade ammonium decavanadate with 98% purity was directly converted to crystallized ammonium metavanadate, yielding a product with 99.75% purity and achieving a vanadium recovery rate of 90.67%. This method successfully realized one-step preparation of ammonium metavanadate with purity of 99.5%. This method significantly simplifies the traditional process flow and provides a new technical approach for the efficient preparation of high-purity ammonium metavanadate.
