Inactivation of harmful algal bloom by an environmentally friendly photocatalyst under photo-Fenton-like degradation process

In the present work, photo-Fenton-like process based on use of Fe2.5Co0.3Zn0.2O4/CuCr-LDH composite was applied for removal green algal cells. First, biological activity proved with antibacterial tests against S. aureus; thereafter, it used Scenedesmus quadricauda cells under process. Interestingly, compared individual processes, displayed a synergistic effect in deactivation The various parameters such as initial concentration cells, hydrogen peroxide (HP), and solution pH total algal. maximuml assessed. Maximum efficiency obtained presence cell 3.5 × 109 mL?1, 0.1 g L?1 composite, HP 10 mM. Furthermore, microscopic SEM images before after their appropriate destruction. reduction chlorophyll content 60 120 min observed revealing destruction walls. Finally, disintegration macromolecules walls by GC-MS technique.
