本文报告了用分光光度计检测柠檬酸液中易碳物的方法及其应用。在浓度较宽的围范内,易碳物的吸光度与浓度呈线性关系。该法具有操作简便,准确度好,精密度高等优点,为柠檬酸生产过程中易碳物的测定提供了一个有效手段。 This article reports the use of spectrophotometers for the detection of readily available carbonates in citric acid solutions. In a wide range of concentrations, the absorbance and concentration of volatile carbon have a linear relationship. The method has the advantages of simple operation, good accuracy and high precision, and provides an effective measure for the determination of the easy carbon in the citric acid production process.
