| 摘要: |
| 依据强力霉素废水组成,使用紫外吸收光谱法测定强力霉素废水中5-磺基水杨酸。该方法测定5-磺基水杨酸的线性范围为1.0×10-7~7.0×10-5mol·L-1,线性相关系数为0.9995(n=9),检出限为6.18×10-8mol·L-1(n=11),相对标准偏差为0.39%(n=11),加标回收率98.1%~102.1%。该方法具有设备成本低、操作简单、选择性好、灵敏度高和线性范围宽等优点,便于实际应用。 |

| Abstract: |
| Sulfosalicylic acid (SSA) is one of the main toxic pollutants in doxycycline waste water. UV spectrophotometry was empolyed to determine sulfosalicylic acid in doxycycline waste water.A linear relationship was obtained between the absorbance and the concentration of 5-SSA over the range from 1.0×10-7 to 7.0×10-4 mol·L-1 with a correlation coefficient of 0.9995(n=9). The detection limit was 6.18×10-8 mol·L-1 (n=11). The relative standard deviation (RSD) for the determination of 5-SSA (4.0×10-6 mol·L-1) was 0.39%(n=11).The recovery of standard addition was 98.1% to 102.1%.This method was successfully applied to the determination of 5-SSA in doxycycline waste water. |
