Abstract:
Objective To study the method and conditions of determination of niclosamide in water. Methods Niclosamide was extracted by mixed extractent, then striped by NaOH. Niclosamide in NaOH solution was determined with dual-wavelength photometry. Results The recovery of niclosamide was 93%. The linear ranger was 0-4. 0 g/m3 and the detectable limit for niclosamide was 0. 042 7 g/m3. The apparent molar absorptivity was 1. 26 ?105 L/(mol?cm). Conclusion Extraction photometry is suitable for determination of niclosamide in water in the field.
