Rapid determination of the content of carboxymethyl cellulose sodium in aqueous solution by a color indicator-assisted spectroscopy

This paper reports on a color indicator-assisted spectrophotometric method for the determination of carboxymethyl cellulose sodium (CMC-Na) content in aqueous solution. Methyl blue (MB) was used as the color indicator and its absorbance at 597 nm can be instantly attenuated when the CMC-Na was intro...
