Al(Ⅲ)溶液的水解─沉淀特性研究─—磷酸根的作用
- HYDROLYSIS-PRECIPITATION CHARACTERISTICS OF ALUMINUM(Ⅲ) SOLUTION AND THE ROLE OF PHOSPHATE RADICAL
- 摘要:采用连续碱滴定方法和X射线衍射及红外光谱分析, 研究了在Al(Ⅲ)-磷酸根溶液体系中, Al(Ⅲ)的水解-沉淀特性, 结果表明, 当P/A1>0.05时, 磷酸根对Al(Ⅲ)的水解-成核-沉淀过程有显着的促进作用, 描述了磷酸根作用的动力学机理。
- Abstract:Hydrolysis-precipitation characteristics of aluminum(Ⅲ)in aluminum(Ⅲ)-phosphate solutions were studied by means of continuous base titration,X-ray diffraction analysis and infrared spectrum analysis.The significanteffect of phosphate radical(P/Al>0.05)on promoting hydrolysis-nucleation-precipitation processes of aluminum(Ⅲ) was observed.The dynamic mecha-nism of phosphate radical in aluminum(Ⅲ)-phosphate solutions was discus-sed.
