Comparison between Nanotechnology and Other Mehods for Removal Cypermethrin Pesticide in Contaminated Water

A large variety ofpesticides are used for killing plant pests in the country and cypermethrin is the most common insecticide in the synthetic pyrethroid family. The entrance into drinking water resources by resistant pollutants can have negative impacts on human health and the environment. Currently, the control of pesticides in groundwater, drinking water and surface water is a serious subject. This paper reviews the previous studies concerning removal methods for cypermethrin pesticides. In recent years, scientists have been tried to design and develop new technologies for removing such pesticides. These include nanotechnology, which has many advantages in comparison to previous methods. The advantages of nanotechnology include effective removal of contaminants, lowering of energy, eco-friendliness and cost-effectiveness in the production of healthy and high-quality water. It is found that nanotechnology is highly efficient in eliminating cypermethrin from water as collagen-CuO nanoparticles can eliminate over 90% of cypermethrin in a short period. The study also provides a comparison between nanotechnology and other methods of removing cypermethrin from contaminated water.
