Removal of Crystal Violet From Water by Iron Oxide Nanoparticles Loaded Green Alga

In this present communication, green lamentous alga, Oedogonium capillare has been collected from Badshahithaul, Uttarakhand, India. The green alga has been exploited to fabricate spindle shaped iron oxide nanoparticles (IONPs) against 10 mM ferric chloride solution. The biofabricated IONPs have been characterized by UV-Vis spectroscopy, Scanning electron microscopy (SEM) and EDAX). The changes of pigment content in Energy-dispersive X-ray analysis ( O. capillare specially Chlorophyll a, Chlorophyll b and carotenoids during production of IONPs have been analyzed and it was observed the amount of all studied pigments decreased after 72h of reaction. The crystal violet (CV) removal capacity of metal free and IONPs loaded O. capillare has been checked by spectroscopic method. Control and IONPs loaded laments of O. capillare showed 65% and 83% of CV removal within 20 min of exposure in aqueous CV solution respectively.
