中文摘要
为建立用分光光度法测定植物油脂中氯化物含量, 采用灰化超声提取法处理样品, 选择60 ℃, 10 min为反应条件, 该方法在0~5.0 mg/L范围内线性关系良好, 线性方程Y=0.0453X+0.0009, 相关系数R2=0.9998, RSD
英文摘要
To establish a spectrophotometry method for determination of chloride in plant oil. Oil samples were ashed in muffle furnace with calcium oxide, and extracted with deionized water in ultrasonic field, then the various reaction conditions were tested and spectrophotometric measure performed quantitatively. The results showed that the optimal reaction condition is 60 ℃ for 10 min, the range of linearity and the detection limit were 0~5.0 mg/L and 0.2 mg/L, respectively. The regression equation was Y=0.0453X+0.0009, correlation coefficient 0.9998. The relative standard deviations was less than 5.0% and the recovery was from 94.93% to 102.62%.
