The adsorption of carminic acid (CA) on glass powder (GP) has been studied polarographically. The adsorption is a two-stage process comprising a fast initial phase and a slower second phase. The rate constant for the first phase increased slightly with increasing dye concentration while the rate constant for the second phase remained almost constant. This indicated the presence of two diffusional processes. In the first phase, CA molecules are adsorbed at the outer sites of the glass particles… CONTINUE READING
