In order to investigate the adsorption effects of the activated
carbon four different trials were performed in a three necked
balloon with the dye solution (200 mg/L Reactive Black 5 and
200 mg/L Procion Red MX-5B) and 0.5 g/L activated carbon. The
adsorption effect of the activated carbon was tested under different
pH values (pH = 3 and pH= 7) at 50 ◦C. And in addition
to this, at pH= 3 the reaction temperature was raised to the
value of the optimized conditions (80 ◦C). And all the results of
these trials were compared with the CWPO at the optimized
conditions
