Abstract:
The Acid 4092 dye solution toxicity after UV/ZnO mediated nanophotocatalysis process using Daphnia magna bioassay was investigated. Daphnia magna has been evaluated as suitable indicator to test effluent toxicity in dyes wastewater. In this study, the parameters such as ZnO nanoparticles load, pH and contact time were analyzed. This study showed that toxicity increases during the UV/ZnO nano-photocatalysis process. Besides, toxicity increases with time. LC50-24 hr, LC50-72 hr, and LC50-96 hr values were 124.9, 111.6, and 91.55 mg/l, respectively.
