摘要
使用改进的实验装置研究钒酸铋颜料制备实验中p H对产物的影响。X射线衍射分析结果表明,在选定实验条件下,产物为四方相为主的四方、单斜两相混合物。p H对钒酸铋颜色有重要影响。酸性条件下颜色偏深,为土黄色;碱性条件下为亮黄色,且p H越大,颜色越淡。推荐反应p H为9,此时产物颜色呈色调较好的亮黄色。
The effects of pH on the synthesis experiment of BiVO4 pigment were studied with improved experimental installation.Under the selected experimental conditions,the product was a mixture of a tetragonal phase,which dominated and a monoclinic one.pH of reaction system had significant influence on product color.Under acidic condition,the product was dark khaki.Under basic condition,product presented bright yellow.The pH=9 reaction system was recommended,because the product had a better bright yellow tone.
