and sodium carbonate on decolouration of acid dye effluent by ozone. Studies were conducted at two different alkaline pH on dye effluent, using Acid Black 1 dye with a concentration of 500 µM. It was found from the literature that alkaline pH favours the faster decolouration of dye effluent than acidic and neutral pH on ozonation.
