Abstract: The textile industry consumes large amounts of water and generates wastewater rich in dyes, toxic chemicals, and organic substances. This coloured effluent poses serious environmental concerns. The present study aimed to evaluate Azolla pinnata as a phytoremediator for decolourizing, detoxifying, and degrading textile effluent and to consider its use for agricultural production. The size and shape of the silver nanoparticles were determined by characterizing their morphology using both a Scanning Electron Microscope (SEM) and a Transmission Electron Microscope (TEM) after they were manufactured using the Sol-gel process. Using Fourier Transform Infrared Spectroscopy (FTIR) in the 4000-400 cm-1 range, the presence of different functional groups on the samples were ascertained. Azolla pinnata-based silver nanoparticles for decolourization, biodegradation of dye in textile industries. Experiments were designed to observe the growth of A. pinnata culture at various dilutions of textile effluent (10, 25, 50, 75, and 100%) and to assess the efficiency of synthesizing nanoparticles that act as adsorbents for pigments in textile effluent. As the incubation time increased the algae achieved greater efficiency in degrading the dyes, reaching 27% after 15 days using 25% filtered effluent wastewater inoculated with 2 g of the algal species Azolla pinnata. At the highest dye concentration (75%), the decolourization efficiency was higher at a 50% dilution of the effluent (84% degradation after 30 days of culture growth). The nanoparticles have been adopted to either remove or reduce less toxic algal biomass, acting as adsorbents due to their increased surface area. Phyco-remediation could prove to be a very effective strategy for tackling pollution of significant environmental concern.
