| Abstract: | Investigations of two analytical methods, visible spectropliotometric and ultraviolet spectrophotometrio for determination of tannic acid were reported. Determined condition and precision were discussed in detail. Results were compared with that of hide powder method.
It has been shown that both methods were rapid and simple, UVwas the more precise one, which had less deviation and was more adaptable to the quantitative analysis of tannic acid. |
