Evaluating the effect of iron nanoparticle amount, reaction time and initial dye concentration on the rate of dye removal in the treatment of wastewater containing acid yellow 36


Abstract

Wastewater in dye factories contains toxic compounds and high levels of COD, BOD, and TOC. These substances harm aquatic and animal life and cause food chain contamination. Thus, it is crucial to find a suitable method to remove these materials. The present study aims to investigate the effect of iron nanoparticle amount, reaction time and initial dye concentration on the rate of dye removal in treatment of wastewater containing acid yellow 36. To carry out this study, 30 experiments were designed using the experiment design software, and different laboratory conditions were applied using the information obtained from this design. Accordingly, the synthetic wastewater was prepared with different amounts of initial dye and then the effect of zero-valent iron nanoparticles on the rate of removal of this substance from the water was investigated. The effect of parameters including the number of iron nanoparticles, the contact time of the nano-adsorbent with the dye solution, and the amount of the initial dye concentration on the rate of dye removal was measured. The results revealed that very high initial dye concentrations and low concentrations of the nano-adsorbent also greatly reduced the removal efficiency. Very high and very low contact times also reduced the removal efficiency. In general, it can be concluded from the present study that the use of the appropriate concentration of zero-valent iron nano-adsorbent is a suitable case for removing the acid yellow 36 in appropriate concentrations.
