Abstract:A practicable analytical method of detecting the colourity of molasses alcohol wastewater by spectrophotometry is discussed in this paper. The measuring conditions have been discussed. The effect of pH value on the absorbance of the molasses alcohol wastewater has been studied especially. The measuring conditions of absorbance and the calculation equation of decoloring ratio have been given in the article and the decoloring ratio can be satisfactorily detected with this method.
Keywords:spectrophotometry  molasse alcohol wastewater  colourity  absorbance  decoloring ratio
