Abstract

The market’s desire to find a new method to replace fossil fuels is growing and this, together with climate change on our planet are acting as a reminder to innovative contrivance methods in the future. Microalgae is a leading candidate having attracted the attention of several types of research to be found innovative processes to make the most of this green gold resulting in a commercial application. The process of separating microalgae cells from the medium is an integral part of this process. Although the variety of application methods such as centrifugation, flocculation, filtration, magnetic nanoparticles It has not been possible to reduce the total cost of the process to a point where it can compete with crude oil. This research will report on the use of an inexpensive commercial nanoparticle (Fe3O4), which has pretreatment in an acid environment before using it in the culture. The preparation of Iron Oxide Nanoparticles Under Acid Control (IONPs_UAC) is a promising method with a simple, fast, and low-cost process with a Harvesting Efficiency (HE) to be higher than 90%  at different species of microalgae such as Parachlorella kessleri, Chlorella Vulgaris, Chlamydomonas reinhardtii and potential for reuse of Iron Oxide nanoparticles (IONPs) and medium in the Process. Furthermore, it presents a promising method for immediate extraction products from a disturbed microalgae cell with the benefit of reducing costs.
