The highHigh amounts of arsenic in groundwater are a threat to the environment. Fortunately, magnetite nanocrystals are capable of purifying contaminated water. However, production methods are expensive and complicated. This study will focus on utilizing common edible kitchen oils as an efficient, cost-effective method to producingproduce magnetite nanocrystals. Through the chemical processes of saponification and acidification, olive oil, soybean oil, and corn oil were used to produce nanocrystals. In this process, oleic acid/1-octadecene was replaced with edible oils, and iron oxohydrate was replaced with rust. If edible oils are used in this process, then olive oil will work the best. First, after curing for one day, saponification resulted in a hard soap. The soap was then boiled with acetic acid, and an organic layer was obtained. The fatty acid mixture was combined with rust, and a black slurry was produced through acidification. The magnetite nanocrystals were then separated from the slurry and dispersed into water.

The results showed that all edible oils were successful in producing magnetite nanocrystals. Olive oil worked the most effectively at producing nanocrystals. Almost fifty grams of black slurry was produced, with twenty grams of magnetite nanocrystals. The data collected supported the initial hypothesis.

Further research on utilizing the kitchen synthesis of magnetite nanocrystals to remove arsenic from water, could be impactful on our environment and prevent conditions from worsening in underdeveloped countries. Future studies will include utilizing oleic, stearic, linoleic, and palmitic acids as controls, as well as other types of edible oils.
