Fig. 5From: Three developed spectrophotometric methods for determination of a mixture of ofloxacin and ornidazole; application of greenness assessment toolsa: Wavelet application on the ratio spectra of OFL in concentration range (2–15 µg/mL) using (5 µg/mL) ORN as a divisor at 285 nm in methanol; b: Wavelet application on the ratio spectra of ORN in concentration range (3–30 µg/mL) using (4 µg/mL) OFL as a divisor at 306 nm in methanolBack to article page
