作者根据有关文献[2]用紫外分光光度法测定朵贝氏溶液苯酚的含量，测定波长为269nm，回归方程为c（μg／ml）＝63．23A＋0．2464，r＝0．9999，在15．0μg／ml～50．0μm／ml平均回收率为99．95，n＝9经测定3批样品的结果（见附表）。紫外分光光度法测定朵贝氏溶液中苯酚的含量
According to the relevant literature [2], the content of phenol in Dobless solution was determined by UV spectrophotometry. The determination wavelength was 269nm. The regression equation was c (μg / ml) = 63.23A + 0.2464, r = 0.9999. .0μg / ml ~ 50.0μm / ml The average recovery was 99.95, n = 9 The results of three batches of samples were determined (see attached table).
