| Abstract: | In this paper, hue of the aqueous solution of p-aminoazobenzene chloride salt (PABS) is determined from the absorption spectrum so as to find a better method to de-colorize this kind of wastewater. The calculation results accord with what is obtained by means of the standard method for color monitoring very well. So, the colorization phe-nomena can be inferred from the absorption spectrum. In PABS solution there exits an equilibrium: form C form A form I . The equilibrium shifts to left with the in-crease of acidity. Form C predominates in strong acidity condition, while from A and form I is dominant in weaker condition in turn. Hue of the solution is determined by the dominating form and changes with the acidity. |
