| Abstract | ||
| UV Derivative spectra were used for the direct quantitative determination of sulfacetamide sodium in distilled water. The quantification was accomplished using the integrated area under the peaks. The zero-order spectrum of sulfacetamide sodium shows an absorption band at = 258 nm, with an max = 14900 l. mol-1. cm-1, the determination limit was (0.55-25.4) g/ml with R2 = 0.9999 and RSD =1.25 %. The determination limits were (0.25-50.80) g/ml for both first and second-order derivatives with R2 = 0.9982, 0.9995 and RSD = 1.60 %, 2.40 % respectively. This indicates a more sensitive and accurate results as compared with the zero-order method. These methods were applied to the direct determination of the samacetamide eye drop. | ||
