微机动力学光度法测定不同低聚合度硅酸的研究及其在甘蔗中存在量分析的应用
Study on Determination of Different Low Polymerized Silicic Acid by Microcomputer Kinetics Spectrophotometry and Its Application to the Sugarcane Analysis
【摘要】 依据单、双和三硅酸与钼酸形成杂多酸的反应速度的不同,建立了同时测定这三种硅酸的微机动力学光度法.此法应用于甘蔗中低聚合度硅酸的测定,结果满意.
【Abstract】 The simultaneous determination of metasilicic, disilicic and trisilicic acid in the heteropoly compound of silicic acid with molybdate was examined by microcomputer kinetics spectrophotometry based on different reaction rate of the metasilicic, disilicic and trisilicic acid with molybdate to form heteropoly compound. The proposed method can be applied to the simultaneous determination of metasilicic, disilicic and trisilicic acid in sugarcane with satisfactory results.
