Abstract :

The color removal of three reactive dyes in an aquatic system without priortreatment was studied. Selected commercial dyes were treated with NaC102 andUV as oxidation agents. Effects of nature of oxidant, temperature, pH ofsolutions, concentration of C107—, contact time of C102— and UV irradiation wereinvestigated. Optimal C102— concentration for color removal in the absence of UVirradiation was found to be 20 mg I for all dyes studied. Combination of UVirradiation and C102— was found to be more effective. C102— dosage between 20mg I and UV irradiation (15 watts) for color removal than individual oxidantwith contact time of 30 minutes was required. The accuracy of method waschecked by measuring the COD of the samples. For determination of colorremoval of samples, Spectrophotometery method was used for measurement ofabsorbance changes of the samples (AA).
