An analytical procedure is described for determining residues of sodium phenobarbital in animal chow at levels as low as 0.14 ppm. The methanol extract is subjected to a liquid-liquid cleanup at pH 13 and 1, further cleaned up on a silica gel column and assayed by high-pressure liquid chromatography by using an ultraviolet absorption detector at 210 nm. Data concerning extraction efficiency, partition values and stability of the chemical in animal chow are also presented.
描述了一种分析方法，用于测定动物饲料中低至0.14 ppm水平的苯巴比妥钠残留量。甲醇提取物在pH 13和pH 1条件下进行液液净化，进一步在硅胶柱上净化，并使用210 nm紫外吸收检测器通过高压液相色谱法进行测定。还给出了有关动物饲料中化学物质的提取效率、分配值和稳定性的数据。
