抗坏血酸钙水溶液颜色检测方法的改进

Optimization of color test of calcium ascorbate solution

为建立一种新的抗坏血酸钙溶液检测方法,使抗坏血酸钙溶液能够在分光光度计上稳定地检测吸光度,以其检测数据指导工艺参数的优化及对成品质量的控制,在制备抗坏血酸钙溶液时加入一种酸试剂,抑制溶液颜色的变化。结果发现,酸试剂的加入保证了抗坏血酸钙溶液吸光度的稳定性,测定结果反映了成品质量的真实情况。该方法灵敏度高,稳定性和重现性好。

A method was established for the analysis of calcium ascorbate. In the test, the absorbance of the solution of calcium ascorbate can be tested steadily in specrrophotometer. The data were used to optimize production process and control prod- uct quality. A kind of acid solvent was put into the solution to prevent the change of color. The acid solvent assures the stabiliry of ab- sorbstance, and the test result reflects its actual quality. The method has better sensitivity, stability and reproducibility.
