Abstract: Water pollution by visible coloured pollutants, such as dyes is a big concern. In this study, a non-viable cyanobacterium Oscillatoria sp. is used to adsorb the toxic anthraquinone dye Alizarin from synthetic aqueous solutions in pursuit of an inexpensive and conveniently accessible biomaterial. The primary study examines key adsorption parameters, Initial solution pH, dye concentration, adsorbent dosage, contact time, and temperature. Systematically, alizarin dye adsorption was examined at a range of pH values (1-6), initial dye concentrations (50-200 mg/L), adsorbent doses (1-10 g/l), temperatures (298K–318K), and contact periods (5-160 minutes). Adsorption was optimized at pH 1, 200 mg/l dye concentration, 4 g/L cyanobacterial dosage, 318K, and 120 minute’s contact duration. Acid pre-treatment (HCl) enhanced the biomass’s ability to absorb Alizarin dye. SEM and FTIR were employed in addition to the determination of cyanobacterial surface area and elemental composition. FT-IR spectra showed few changes after dye sorption, demonstrating the involvement of biomaterial cell wall surface functional groups.
